DESCRIPTION

The M54/74HC540 and HC541 are high speed

CMOS OCTAL BUS BUFFERS (3-STATE)

fabricated in silicon gate C2MOS technology. They

have the same high speed performance of LSTTL

combined with true CMOS low power consumption.

The HC540 is an inverting buffer and HC541 is a non

inverting buffer.

The 3 STATE control gate operates as a two input

AND such that if either G1 and G2 are high, all eight

output are in the high impedance state. In order to

enhance PC board layout, the HC540 and HC541

offers a pinout having inputs and outputs on

opposite sides of the package.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
