The M54/74HC174 is a high speed CMOS HEX D-

TYPE FLIP-FLOP WITH CLEAR fabricated in sili-

con gate C

speed performance of LSTTL combined with true

CMOS low power consumption.

Information signals applied to D inputs are trans-

fered to the Q output on the positive going edge of

the clock pulse. When the CLEAR input is held low,

the Q outputs are held low independently of the

other inputs. All inputs are equipped with protection

circuits against static discharge and transient ex-

cess voltage.
