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.
