DESCRIPTION

The M54/74HC137 is a high speed CMOS 3 TO 8LINE

DECODER/LATCH (INVERTING) fabricated in silicon

gate C²MOS technology. It has the same high speed

performance of LSTTL combined with true CMOS low

power consumption. This device is a 3 to 8line decoder

withlatches on thethree address inputs. When GL goes

from low tohigh, theaddress present at theselect inputs

(A, B and C) is stored in the latches. As long as GL re-

mains high no address changes will be recognized. Out-

put enable pins G1 and G2, control the state of the

outputs independently of the select or latch-enable in-

puts. All the outputs are high unless G1 is high and G2

is low. The HC137 is ideally suited for the implementa-

tion of glitch-free decoders in stored-address applica-

tions in bus oriented systems. All inputs are equipped

withprotection circuits against staticdischarge and tran-

sient excess voltage.
