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 V
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.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
