M74HC238 General Description
The M54/74HC238 is a high speed CMOS3 to 8 line decoder fabricated insilicon gate C2MOStechnology. It has the same high speed performance of LSTTL combined with true CMOSlowpower consumption. If the device is enabled, 3 binary select inputs (A, Band C)determine whichoneof outputs willgo high. Enable input G1 is held "Low" or either G2A or G2B is held "High" decoding function is inhibited and all the 8 outputs go low. Three enable inputs are provided to ease cascade connection and application of this address decoder in memory systems.
All inputs are equipped with protection circuits against static discharge and transient excess voltage.
