DESCRIPTION

The M54/74HC131 is a high speed CMOS 3 TO 8
LINE DECODER/LATCH fabricated in silicon gate
C2MOS technology.

It has the same high speed performance of LSTTL
combined withtrue CMOSlowpower consumption.
This deviceis a DECODER/LATCHcapable of se­lectingarbitrarilyoneof eight outputsbythreebinary
inputs A,B, and C, in thiscase, the selected output
is at logic”low”.

Also, whenENABLE input G1is setlowor ENABLE
inputG2is sethigh,selection isinhibited regardless
of otherinputsignals and all theoutputsare athigh.
All inputs are equipped with protection circuits
against static discharge and transient excess volt­age.
