74HC7541; 74HCT7541 Octal Schmitt trigger buffer/line driver; 3-state Rev. 6 — 16 December 2013 Product data sheet 1. General description The 74HC7541; 74HCT7541 is an 8-bit buffer/line driver with Schmitt-trigger inputs and 3-state outputs. The device features two output enables (OE1 and OE2). A HIGH on OEn causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of V . Schmitt trigger inputs transform slowly changing input signals into sharply defined CC jitter-free output signals. 2. Features and benefits  Non-inverting outputs  Low-power dissipation  Input levels: For 74HC7541: CMOS level For 74HCT7541: TTL level  Complies with JEDEC standard no. 7A  ESD protection: HBM JESD22-A114F exceeds 2000V MM JESD22-A115-A exceeds 200V  Multiple package options  Specified from 40C to +85C and from 40C to +125C 3.
