DESCRIPTION

The M54/74HCT174 is a high speed CMOS HEX D-

TYPE FLIP-FLOP WITH CLEAR fabricated in silicon

gate C2MOS technology. It has the same high speed

performance of LSTTL combined with true CMOS

low power consumption.

Information signals applied to D inputs are transfered

to the Q output on thepositive going edge of the clock

pulse. When the CLEAR input is held low, the Q out-

puts are held low independently of the other inputs.

This integrated circuit has input and output charac-

teristics that are fully compatible with 54/74 LSTTL

logic families. M54/74HCT devices are designed to

directly interface HSC2MOS systems with TTL and

NMOS components. They are also plug in replace-

ments for LSTTL devices giving a reduction of power

consumption. All inputs are equipped with protection

circuits against static discharge and transient excess

voltage.
