SN74HCT273PW

Flip Flops Overview

The SN74HCT273PW is an octal D-type flip-flop from the Texas Instruments 74HCT logic family, housed in a 20-TSSOP package. It features positive-edge triggering and a master reset function with non-inverting outputs. The device operates within a supply voltage range of 4.5V to 5.5V. Key electrical parameters include a maximum propagation delay of 29ns at 5.5V with 50pF load, output currents of 4mA for both high and low states, and a static current of 8µA. It supports a clock frequency up to 37MHz and functions across a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Integrates eight independent D-type flip-flops into a single unit for efficient data storage.
• Provides a global master reset input to clear all stored data simultaneously.
• Ensures compatibility with standard TTL logic inputs through HCT series design.
• Delivers non-inverting outputs for direct signal interfacing.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
