Description

The M54/74HC155 is a high speedCMOS DUAL 2- TO-4 LINE DECODER fabricated in silicon gate C2MOS technology.

M54/74HC155 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).

Whenboth decoders are enabled by thestrobes, 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 M54/74HC155 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.

M54/74HC155 All inputs are equipped with protection circuits against static discharge and transient excess voltage.
