SN74AHCT273DW

Flip Flops Overview

The SN74AHCT273DW is an octal D-type flip-flop from the Texas Instruments AHCT logic family, designed for high-speed digital applications. It features a single master reset input and non-inverting outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a maximum propagation delay of 9.2 ns at 5 V with a 50 pF load, a maximum clock frequency of 130 MHz, and output drive capabilities of -8 mA (high) and 8 mA (low). It is housed in a 20-pin SOIC package.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops on a single chip.
• High-speed CMOS technology ensuring low power consumption and fast switching speeds.
• CMOS-compatible inputs allowing direct interfacing with standard CMOS logic devices.
• Single master reset function to initialize all flip-flops simultaneously.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register storage for temporary data holding
• Shift register configurations
• Buffering and latching operations in digital systems

Flip Flops Procurement Notes

Verify component authenticity through authorized channels. Confirm that the specific ordering suffix matches the required package type and temperature rating. Check for RoHS compliance status relevant to your region. Ensure the datasheet version aligns with current design specifications. Validate pinout compatibility during integration planning.

Flip Flops Selection Notes

Select this component when an octal latch with fast propagation delay is required. The AHCT series ensures compatibility with CMOS inputs while maintaining TTL-like performance. Consider the SOIC-20 package for surface-mount assembly. Evaluate the 4.5 V to 5.5 V operating range against system power constraints. Compare propagation delays against other logic families for timing accuracy.

Flip Flops Part Context

This part belongs to the SN74AHCT273 series, which includes variants like SN74AHCT273PWR and SN74AHCT273QDGSRQ1. These components share similar logical functionality but differ in packaging, automotive qualification, or speed grades. The DW suffix specifically denotes the SOIC-20 surface-mount package format used in this variant.

Flip Flops Replacement Considerations

SN74AHCT273PWR offers identical logical functionality in a TSSOP-20 package. SN74AHC273DWR provides similar performance in the AHC series with a wider voltage range. SN74ALS273DW is a legacy ALS variant with different electrical characteristics. Verify pinout and voltage compatibility before substitution.
