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 M54HC540
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.
