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.

(*) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load.
(Refer to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD VCC fIN + ICC
