DESCRIPTION
The M54/74HC153 and M54/74HC253 are high
speed CMOS DUAL 4-CHANNEL MULTIPLEXERS
fabricated with silicon gate C²MOS technology.
Both achieve high speed operation, similar to equi-
valent LSTTL, while maintaining the CMOS low
power dissipation.
The designer has a choice of complementary output
(HC153) and 3-state output (HC253).
Each of these data (1C0-1C3, 2C0-2C3) is selected
by the two address inputs A and B.
Separate strobe inputs (1G, 2G) are provided for
each of the two four-line sections. The strobe input
(G) can be used to inhibit the data output ; the output
of HC 153 is fixed at a low level and the output of
HC253 is a high impedance, while the strobe input
is held low.
All inputs are equipped with protection circuits
against static discharge and transient excess volt-
age.
