SN74HCT273DWR

Flip Flops Overview

The SN74HCT273DWR is an octal D-type flip-flop from the Texas Instruments 74HCT logic family, housed in a 20-pin TSSOP package. It features eight non-inverting outputs and a master clear input triggered on the positive edge of the clock signal. The device operates within a supply voltage range of 4.5 V to 5.5 V, ensuring compatibility with standard TTL-driven systems. Key electrical specifications include a maximum propagation delay of 29 ns at 5.5 V with a 50 pF load, static current consumption of 8 µA, and output drive capabilities of 4 mA for both high and low states.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit
• TTL-compatible inputs allowing direct interfacing with standard logic families
• Master clear function enables synchronous data storage controlled by positive-edge clocking

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• General-purpose register storage applications
• Shift register implementations requiring TTL-level interface compatibility

Flip Flops Procurement Notes

Verify the specific suffix 'DWR' corresponds to the TSSOP-20 package and reel packaging format when sourcing. Confirm RoHS compliance status and ensure the operating temperature range meets system requirements. Cross-reference manufacturer part numbers against distributor listings to avoid obsolete or discontinued variants.

Flip Flops Selection Notes

Select this component when designing systems that require multiple flip-flops with TTL-compatible input thresholds. The HCT series is appropriate for interfaces between older TTL logic and modern CMOS outputs. Consider the TSSOP package dimensions for PCB layout constraints and thermal management requirements during operation.

Flip Flops Part Context

This component belongs to the SN74HCT273 series of octal D-type flip-flops manufactured by Texas Instruments. It is part of the broader 74HCT logic family, which bridges the gap between HC (High-speed CMOS) performance and HCT (High-speed CMOS TTL-compatible) input levels. The device serves as a fundamental building block for sequential logic design in digital electronics.

Flip Flops Replacement Considerations

SN74HCT273PW: Same logical function but utilizes a TSSOP-20 tube package instead of tape-and-reel. SN74HCT273PWR: Identical electrical characteristics and pinout, packaged in TSSOP-20 tape-and-reel format.
