GENERAL DESCRIPTION
The 74HC/HCT7541 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/HCT7541 are octal Schmitt trigger
non-inverting buffer/line drivers with 3-state outputs. The
3-state outputs are controlled by the output enable inputs
OE
1
and OE
2
.
A HIGH on OE
n
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 “7541” is identical to the “541” but has hysteresis on
the data inputs.
