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 with true CMOS low power consumption.
This device is a DECODER/LATCH capable of selecting arbitrarily one of eight outputs by three binary
inputs A, B, and C, in this case, the selected output
is at logic ”low”.
Also, when ENABLE input G1 is set low or ENABLE
input G2 is set high, selection is inhibited regardless
of other input signals and all the outputs are at high.
All inputs are equipped with protection circuits
against static discharge and transient 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
