The M74HC541 is an opposite sides of the package. inverting buffer. All inputs are equipped with protection circuits The 3-STATE control gate operates as a two input against static discharge and transient excess AND such that if either G1 and G2 are high, all voltage. eight output are in the high impedance state. In PIN CONNECTION AND IEC LOGIC SYMBOLS August 2001 1/10 M74HC540 INPUT AND OUTPUT EQUIVALENT CIRCUIT PIN DESCRIPTION
