DESCRIPTION

The M54/74HC352 and M54/74HC353 are high

speed CMOS DUAL 4 CHANNEL MULTIPLEXERS

INVERTING fabricated with silicon gate C

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 (HC352) and 3 state output

(HC353). 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. Taking the strobe

input (1G, 2G) high inhibits the outputs. The output

of HC352 is fixed at logic low level and the output of

HC353 has a high impedance, unconditionally.

All inputs are equipped with protection circuits

against static discharge and transient excess volt-

age.
