All of the outputs are low LINE DECODER fabricated with silicon gate unless G1 is high and G2 is low. The M74HC237 C2MOS technology. is ideally suited for the implementation of When GL goes from low to high, the address glitch-free decoders in stored-address present at the select inputs (A, B, C) is stored in applications in bus oriented systems. the latches. As long as GL remains high no All inputs are equipped with protection circuits address changes will be recognized. Output against static discharge and transient excess enable controls, G1 and G2 control the state of the voltage. outputs independently of the select or PIN CONNECTION AND IEC LOGIC SYMBOLS July 2001 1/11
