DESCRIPTION
The M54/74HC155 is a high speed CMOS DUAL 2TO-4 LINE DECODER fabricated in silicon gate
C2MOS technology.
It has the same high speed performance of LSTTL
combined with true CMOS low power consumption.
It features dual 1-TO-4 line demultiplexers with individual strobe inputs (1G and 2G), individual data inputs (1C and 2C) and common binary address
inputs (A and B).
When both decoders are enabled by the strobes, the
inverted output of 1C data and non-inverted output
of 2C data will be brought to the select output pins
of each sections. A 1-TO-8 line demultiplexer can
also be easily built up by providing a data signal to
both 1C and 2C inputs ; the output order from the
msb is 1Y3, 1Y2, 1Y1, 1Y0, 2Y3, 2Y2, 2Y1, 2Y0.
This device can be used as a 2-to-4 line decoder or
a 3-to-8 line decoder when 1C is held high and 2C
is held low.
All inputs are equipped with protection circuits
against static discharge and transient excess voltage.
