The output enables of the device control whether the information from the A inputs go to the Y outputs. These enable pins cause the device to go into high Z if either OE1 or OE2 are high. The OEs should be tied to V through a pull CC up resistor to ensure the high impedance state during power up or power down; the minimum value of the resistorisdeterminedbythecurrentsinkingcapabilityofthedriver. 8.2 Functional Block Diagram 1 OE1 19 OE2 2 18 A1 Y1 ToSevenOtherChannels Copyright © 2016,Texas Instruments Incorporated Figure4.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 9.1 Application Information SN74HC541 is a wide range CMOS device that can be used over large voltage ranges. The device can be used anywhere from 2 to 6 Volts. The device can drive up to 6 mA of current at 5 Volts. This makes it perfect for driving bus lines directly or up to 15 LSTTL Loads. It can be used to drive anything from micro controllers and systemlogicdevicestoLEDs. 9.2 Typical Application OE1 VCC OE2 A1 Y1 Microcontroller System Logic LEDs Microcontroller or A8 Y8 System Logic GND Copyright © 2016,Texas Instruments Incorporated Figure5. TypicalApplicationDiagram 9.2.1 DesignRequirements This device uses CMOS technology and has a wide voltage range. Take care to avoid pulling too much current from the outputs as to not exceed 6 mA. Also, take care to not go over V voltage to avoid damage to the CC device. 9.2.2 DetailedDesignProcedure 1.

SN54HC541,SN74HC541 www.ti.com SCLS305D–JANUARY1996–REVISEDSEPTEMBER2016 10 Power Supply Recommendations The power supply can be any voltage between the MIN and MAX supply voltage rating located in the RecommendedOperatingConditionstable. Each V pin should have a good bypass capacitor to prevent power disturbance. For devices with a single CC supply, 0.1-μF is recommended; if there are multiple V pins, then 0.01-μF or 0.022-μF is recommended for CC each power pin. It is acceptable to parallel multiple bypass caps to reject different frequencies of noise. A 0.1-μF and a 1-μF are commonly used in parallel. The bypass capacitor should be installed as close to the power pin as possibleforbestresults. 11 Layout 11.1 Layout Guidelines Whenusingmultiplebitlogicdevicesinputsshouldneverfloat. In many cases, functions or parts of functions of digital logic devices are unused, for example, when only two inputs of a triple-input AND gate are used or only 3 of the 4 buffer gates are used. Such input pins should not be left unconnected because the undefined voltages at the outside connections result in undefined operational states. The Recommended Operating Conditions section specifies the rules that must be observed under all circumstances. All unused inputs of digital logic devices must be connected to a high or low bias to prevent them from floating. The logic level that should be applied to any particular unused input depends on the function of the device. Generally they will be tied to GND or V whichever makes more sense or is more convenient. It is CC generally acceptable to float outputs, unless the part is a transceiver. If the transceiver has an output enable pin, it disables the output section of the part when asserted. This does not disable the input section of the I/Os, so theycannotfloatwhendisabled. 11.2 Layout Example V cc Input Unused Input Output Unused Input Output Input Figure7.

PACKAGE OPTION ADDENDUM www.ti.com 24-Aug-2018 (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs. LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
