详细描述

 74HC7540 - Octal Schmitt trigger buffer/line driver; 3-state; inverting

 
 
FEATURES
 Inverting outputs
 Schmitt trigger action on all data inputs
 Output capability: bus driver
 ICC category: MSI
GENERAL DESCRIPTION
The 74HC/HCT7540 are high-speed Si-gate CMOS
devices and are pin compatible with low power Schottky
TTL (LSTTL). They are specified in compliance with
JEDEC standard no. 7A.
 
The 74HC/HCT7540 are octal Schmitt trigger inverting
buffer/line drivers with 3-state outputs. 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.
The Schmitt trigger action in the data inputs transforms
slowly changing input signals into sharply defined
jitter-free output signals.
The “7540” is identical to the “540” but has hysteresis on
the data inputs.
