DESCRIPTION

The 74HC540 is an advanced high-speed CMOS

OCTAL BUS BUFFER (3-STATE) fabricated with

silicon C2MOS technology. The M74HC541 is an

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 M74HC540

offer 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.
