DESCRIPTION
The M54/74HC153 and M54/74HC253 are high
speedCMOSDUAL4-CHANNEL MULTIPLEXERS
fabricated with silicon gate C2MOS technology.
Bothachieve highspeed operation, similar to equivalent LSTTL, while maintaining the CMOS low
powerdissipation.
The designer has a choiceof complementary output
(HC153) and3-stateoutput (HC253).
Eachofthesedata(1C0-1C3, 2C0-2C3) isselected
by the two address inputs A and B.
Separate strobe inputs (1G, 2G) are provided for
eachof the two four-line sections. The strobeinput
(G)canbe usedto inhibit thedataoutput ;theoutput
of HC 153 is fixed at a low level and the output of
HC253 is a high impedance, while the strobeinput
is heldlow.
All inputs are equipped with protection circuits
against static discharge and transient excess voltage.
