Product specification
Octal buffer/line driver; 3-state
74HC/HCT541
FEATURES
Non-inverting outputs
Output capability: bus driver

CC
category: MSI
GENERAL DESCRIPTION
The 74HC/HCT541 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/HCT541 are octal 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 “541” is identical to the “540” but has non-inverting
outputs.
