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.
