MC74LCX16373 Low-Voltage CMOS 16-Bit Transparent Latch With 5 V−Tolerant Inputs and Outputs (3−State, Non−Inverting) http://onsemi.com The MC74LCX16373 is a high performance, non−inverting 16−bit transparent latch operating from a 2.3 V to 3.6 V supply. The device is byte controlled. Each byte has separate Output Enable and Latch Enable inputs. These control pins can be tied together for full 16−bit operation. 48 High impedance TTL compatible inputs significantly reduce current 1 loading to input drivers while TTL compatible outputs offer improved TSSOP−48 switching noise performance. A V specification of 5.5 V allows I DT SUFFIX MC74LCX16373 inputs to be safely driven from 5.0 V devices. CASE 1201 The MC74LCX16373 contains 16 D−type latches with 3−state 5.0 V−tolerant outputs. When the Latch Enable (LEn) inputs are HIGH, MARKING DIAGRAM data on the Dn inputs enters the latches. In this condition, the latches are transparent, i.e., a latch output will change state each time its D input 48 changes. When LE is LOW, the latches store the information that was present on the D inputs a setup time preceding the HIGH−to−LOW transition of LE. The 3−state outputs are controlled by the Output LCX16373G AWLYYWW Enable (OEn) inputs. When OE is LOW, the outputs are enabled. When OE is HIGH, the standard outputs are in the high impedance state, but this does not interfere with new data entering into the latches. 1 Features A = Assembly Location • Designed for 2.3 to 3.6 V V Operation WL = Wafer Lot CC • YY = Year 5.4 ns Maximum t pd WW = Work Week • 5.0 V Tolerant − Interface Capability With 5.0 V TTL Logic G = Pb−Free Package • Supports Live Insertion and Withdrawal • I Specification Guarantees High Impedance When V = 0 V ORDERING INFORMATION OFF CC • See detailed ordering and shipping information in the package LVTTL Compatible dimensions section on page 3 of this data sheet. • LVCMOS Compatible • 24 mA Balanced Output Sink and Source Capability • Near Zero Static Supply Current in All Three Logic States (20 (cid:2)A) Substantially Reduces System Power Requirements • Latchup Performance Exceeds 500 mA • ESD Performance: ♦ Human Body Model >2000 V ♦ Machine Model >200 V • These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant © Semiconductor Components Industries, LLC, 2012 1 Publication Order Number: October, 2012 − Rev. 11 MC74LCX16373/D
