The M54/74HC298 is a high speed CMOS QUAD 2-

CHANNEL MULTIPLEXER/REGISTER fabricated

in silicon gate C2MOS technology.

PIN CONNECTIONS (top view)

It has the same high speed performance of LSTTL

combined with true CMOS low power consumption.

These circuits are controlled by the signals WORD

SELECT and CLOCK. When the WORD SELECT

input is taken low Word 1 (A1, B1, C1 and D1) is

presented to the input of the flip-flops, and when

WORD SELECT is high Word 2 (A2, B2, C2 and D2)

is presented to the inputs of the flip-flops. The select

word is clocked to the output terminals on the nega-

tive edge of the clock pulse. All inputs are equipped

with protection circuits against static discharge and

transient excess voltage.
