DESCRIPTION
The M74HC298 is an high speed CMOS QUAD 2
CHANNEL MULTIPLEXER/REGISTER fabricated
with silicon gate C2MOS technology.
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 negative edge of the clock pulse.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
