General Description

The MM74HCT273 utilizes advanced silicon-gate CMOS technology. It has an input threshold and output drive similar 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 outputs 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.
