DESCRIPTION

The M54/74HC238 is a high speed CMOS 3 to 8 line

decoder fabricated insilicongate C²MOStechnology.

It has the same high speed performance of LSTTL

combined with true CMOSlow power consumption. If

the device is enabled, 3 binary select inputs (A, B and

C)determine whichoneof outputs willgohigh. Enable

input G1 is held ”Low” or either G2A or G2B is held

”High” decoding function is inhibited and all the 8 out-

putsgo low. Three enable inputs are provided to ease

cascade connection and application of this address

decoder in memory systems.

Allinputs are equipped with protection circuits against

static discharge and transient excess voltage.
