DESCRIPTION
The M54/74HC298 isa high speed CMOSQUAD2-
CHANNEL MULTIPLEXER/REGISTER fabricated
in silicon gate C
2
MOS technology.
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
WORDSELECT ishighWord 2(A2, B2,C2 andD2)
is presented totheinputs of theflip-flops.The select
word is clocked tothe output terminals on the nega-
tive edge of theclock pulse. All inputs are equipped
with protection circuits against static discharge and
transient excess voltage.
