74HC7540; 74HCT7540

Octal Schmitt trigger buffer/line driver; 3-state; inverting

Rev. 4 — 31 December 2012

Product data sheet

1. General description

The 74HC7540; 74HCT7540 is a high-speed Si-gate CMOS device and is pin compatible

with Low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard

No. 7A.

The 74HC7540; 74HCT7540 provides eight inverting buffer/line drivers with 3-state

outputs and Schmitt-trigger action. The 3-state outputs are controlled by the output enable

inputs OE1 and OE2. A HIGH on OEn causes the outputs to assume a high-impedance

OFF-state. Schmitt trigger action on the data inputs transforms slowly changing input

signals into sharply defined, jitter-free output signals.

The 74HC7540; 74HCT7540 is identical to the 74HC540; 74HCT540 but has hysteresis

on the data inputs.

2. Features and benefits

 Inverting outputs

 Low-power dissipation

 ESD protection:

 HBM JESD22-A114F exceeds 2000 V

 MM JESD22-A115-A exceeds 200 V

 Multiple package options

 Specified from 40 C to +85 C and from 40 C to +125 C
