The M54/74HC354 is a high speed CMOS 8-CHAN-

NEL MULTIPLEXER/REGISTER (3-state) fabri-

cated in silicon gate C

same high speed performance of LSTTL combined

with true CMOS low consumption.

This device contains an 8 channel digital multiplexer

with an 8-bit input data register and a 3-bit address

input register with 3-state outputs. The one of eight

input data will be provided on the Y output pin (non-

inverted output) and W output pin (inverted output)

determined by the address data.

The information at the data inputs (D0 to D7) is

stored in the 8-bit latch at the negative pulse on DC

input. The information at the address inputs (S0 to

S2) is stored in the 3-bit latch at the negative pulse

on SC input. These outputs are disabled to be high-

impedance when input G1 is held high, input G2 is

held high or input G3 is held low. This device is suit-

able for interfacing with bus lines in a bus organized

system.

The M54/74HC354 is similar in function to the

M54/74HC356, which has an 8-bit flip-flop as the

data register instead of an 8-bit latch. All inputs are

equipped with protection circuits against static dis-

charge and transient excess voltage.
