DESCRIPTION
The M54/74HC540 and HC541 are high speed
CMOS
OCTAL
BUS
fabricated in silicon gate C
2
MOS technology. They
have the same high speed performance of LSTTL
combined withtrue CMOS lowpower consumption.
TheHC540isaninvertingbufferandHC541isa non
inverting buffer.
The 3 STATE control gate operates as a two input
AND such that ifeither G1 and G2 are high,all eight
output are in the high impedance state. In order to
BUFFERS
(3-STATE)
enhance PC board layout, the HC540 and HC541
offers a pinout having inputs and outputs on
opposite sides of thepackage.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
