The M54/74HC273 is a high speed CMOS OCTAL

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-

ferred to the Q outputs on the positive-going edge

of the clock pulse.

When the CLEAR input is held low, the Q output are

in the low logic level independent of the other inputs.

All inputs are equipped with protection circuits

against static discharge and transient excess volt-

age.
