DESCRIPTION

The M74HC155 is an high speed CMOS QUAD

2-INPUT NAND GATE fabricated with silicon gate

MOS technology.

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

PIN CONNECTION AND IEC LOGIC SYMBOLS

-O

output pins of each sections. A 1 to 8 line

demultiplexer can also 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.
