MM74HC540 MM74HC541
Inverting Octal 3-STATE Buffer Octal 3-STATE Buffer
General Description
The MM74HC540 and MM74HC541 3-STATE buffers uti-
lize advanced silicon-gate CMOS technology. They pos-
sess high drive current outputs which enable high speed
operation even when driving large bus capacitances.
These circuits achieve speeds comparable to low power
Schottky devices, while retaining the advantage of CMOS
circuitry, i.e., high noise immunity, and low power consump-
tion. Both devices have a fanout of 15 LS-TTL equivalent
inputs.
The MM74HC540 is an inverting buffer and the
MM74HC541 is a non-inverting buffer. The 3-STATE con-
trol gate operates as a two-input NOR such that if either G1
or G2 are HIGH, all eight outputs are in the high-imped-
ance state.
In order to enhance PC board layout, the MM74HC540 and
MM74HC541 offers a pinout having inputs and outputs on
opposite sides of the package. All inputs are protected from
damage due to static discharge by diodes to V
CC
and
ground.
