MM74HCT273WMX Description

Short technical summary and product information.

The MM74HCT273WMX from ON Semiconductor is an octal D-type flip-flop with a clear function. This device utilizes advanced silicon-gate CMOS technology, offering input thresholds and output drive similar to LS-TTL while maintaining low CMOS standby power. It is designed for positive edge-triggered operation, with independent Q outputs for each flip-flop.

 

Key electrical characteristics include a supply voltage range of 4.5V to 5.5V, a maximum clock frequency of 68 MHz, and a typical propagation delay of 18 ns. The device also features a low quiescent current of 160 µA maximum and an input capacitance of 6 pF. The asynchronous clear input forces all outputs LOW when it is LOW.

 

Packaged in a 20-SOIC surface-mount case, the MM74HCT273WMX is suitable for various digital logic applications. Its design allows it to interface with TTL and NMOS components to CMOS components, making it a potential plug-in replacement to reduce system power consumption in existing designs.
