- CMOS Input Compatibility, Il 1µA at VOL, VOH
The ’HC273 and ’HCT273 high speed octal D-Type flip-flops
with a direct clear input are manufactured with silicon-gate
CMOS technology. They possess the low power consumption
of standard CMOS integrated circuits.
Information at the D inputis transferred to the Q outputs on
the positive-going edge of the clock pulse. All eight flip-flops
are controlled by a common clock (CP) and a common reset
(MR). Resetting is accomplished by a low voltage level
independent of the clock. All eight Q outputs are reset to a
logic 0.
