SN74AHC273DBR

Flip Flops Overview

The SN74AHC273DBR is an octal D-type flip-flop from the Texas Instruments AHC logic family, housed in a 20-pin SSOP package. It operates within a supply voltage range of 2 V to 5.5 V and supports a maximum clock frequency of 130 MHz. The device features a propagation delay of 14.8 ns and provides push-pull outputs with drive capabilities of -8 mA (high) and 8 mA (low). It functions across an extended industrial temperature range of -40°C to +125°C.

Flip Flops Feature Summary

• Integrates eight independent D-type flip-flops into a single unit for high-density data storage applications.
• Utilizes advanced CMOS technology to achieve low power consumption while maintaining high-speed performance.
• Provides non-inverting outputs that directly reflect the state of the input data upon clock triggering.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register file implementations in embedded systems
• Data buffering and latching in digital communication interfaces

Flip Flops Procurement Notes

Verify the specific suffix 'DBR' corresponds to the SSOP-20 package and tape-and-reel shipping configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments, as these parameters are subject to change based on manufacturing availability and regional supply chain conditions.

Flip Flops Selection Notes

Select this component when an octal register is required with a 20-pin surface-mount footprint. Ensure the system voltage aligns with the 2 V to 5.5 V operating range. Consider the 14.8 ns propagation delay and 130 MHz maximum frequency against system timing requirements to ensure signal integrity at the intended operating speed.

Flip Flops Part Context

This part belongs to the SN74AHC273-Q1 series of automotive-grade octal D-type flip-flops. It shares functional compatibility with other members of the AHC family but is distinguished by its specific SSOP-20 packaging and reel-based distribution format designed for automated surface-mount assembly processes.

Flip Flops Replacement Considerations

SN74AHC273DWR: Offers identical electrical characteristics and functionality but utilizes a TSSOP-20 package instead of SSOP-20. Verify pinout compatibility and physical dimensions before substituting to ensure board layout alignment.
