IC M74HC155

DESCRIPTION
The M74HC155 is an high speed CMOS QUAD
2-INPUT NAND GATE fabricated with silicon gate
C2MOS 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
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.

HIGH SPEED:
tPD = 13ns (TYP.) at VCC = 6V
LOW POWER DISSIPATION:
ICC = 4mA(MAX.) at TA=25
