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.
