SN74HCT273PWT

Flip Flops Overview

The SN74HCT273PWT is an octal D-type flip-flop from the Texas Instruments SN74HCT273 series, housed in a 20-TSSOP package. It features positive-edge triggering and includes a master reset function. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a maximum propagation delay of 29 ns at 5.5 V with a 50 pF load, a maximum clock frequency of 37 MHz, and static current consumption of 8 µA. Output drive capability is specified at 4 mA for both high and low states.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type storage elements within a single integrated circuit.
• Positive-edge triggered operation synchronized with the clock signal input.
• Integrated master reset functionality to initialize all outputs simultaneously.
• CMOS output structure designed for standard TTL logic compatibility.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• General-purpose register implementations
• Shift register configurations

Flip Flops Procurement Notes

Verify the specific suffix 'PWT' against official manufacturer documentation to confirm tape-and-reel packaging details and exact pinout alignment. Ensure the selected component matches the required operating temperature range and voltage specifications for the target application environment before finalizing procurement.

Flip Flops Selection Notes

Select this component when an octal storage solution with TTL-compatible inputs is required. The HCT series ensures compatibility with standard 5 V logic systems. Consider the 20-TSSOP package constraints regarding board space and thermal management during the design phase.

Flip Flops Part Context

This part belongs to the SN74HCT273 family of octal D-type flip-flops manufactured by Texas Instruments. The HCT designation indicates High-speed CMOS technology optimized for 5 V operation while maintaining compatibility with TTL logic levels. The PWT suffix typically denotes surface-mount packaging in a reel format.

Flip Flops Replacement Considerations

SN74HCT273PWG4 is a documented equivalent variant within the same product line offering identical logical functionality and pinout compatibility.
