The M54HC541 is a non inverting buffer. PIN CONNECTION 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 M54HC541 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.
