MM74HCT273
Octal D-Type Flip-Flop with Clear
General Description
The MM74HCT273 utilizes advanced silicon-gate CMOS
technology. It has an input threshold and output drive simi-
lar to LS-TTL with the low standby power of CMOS.
These positive edge-triggered flip-flops have a common
clock and clear-independent Q outputs. Data on a D input,
having the specified set-up and hold time, is transferred to
the corresponding Q output on the positive-going transition
of the clock pulse. The asynchronous clear forces all out-
puts LOW when it is LOW.
All inputs to this device are protected from damage due to
electrostatic discharge by diodes to VCC and ground.
MM74HCT devices are intended to interface TTL and
NMOS components to CMOS components. These parts
can be used as plug-in replacements to reduce system
power consumption in existing designs.
