SN74AHCT273NSR

Flip Flops Overview

The SN74AHCT273NSR is an octal D-type flip-flop from Texas Instruments, featuring a clear function and non-inverting outputs. It operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes a 20-SOIC package for surface-mount installation. It supports a maximum clock frequency of 130 MHz with a propagation delay of 9.2 ns at 5 V and 50 pF load. Output drive capability is specified at 8 mA for both high and low states. The component functions reliably across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Integrates eight independent D-type flip-flops with positive-edge triggering into a single unit.
• Includes a dedicated clear input that asynchronously resets all flip-flops to a low state.
• Features CMOS-compatible inputs allowing direct interfacing with TTL logic systems.
• Provides standard non-inverting outputs suitable for general-purpose data storage applications.

Flip Flops Applications

Flip Flops Procurement Notes

Verify the specific suffix 'NSR' corresponds to the SOIC-20 package and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations. Ensure the procurement channel provides valid traceability for automotive or industrial grade requirements if applicable. Cross-reference the datasheet revision date to confirm current electrical specifications match design requirements.

Flip Flops Selection Notes

Select this component when an octal storage solution with TTL-compatible inputs is required. The AHCT series ensures compatibility with standard 5V logic families while offering improved switching speeds compared to older HCT variants. Consider the 20-SOIC package dimensions for PCB layout constraints. Evaluate the 130 MHz clock limit against system timing requirements to ensure signal integrity during high-speed data transitions.

Flip Flops FAQ

What is the function of the clear input?

The clear input asynchronously resets all eight flip-flops to a low state, regardless of the clock or data inputs.

Is the output inverting or non-inverting?

The SN74AHCT273NSR features non-inverting outputs, meaning the Q output follows the D input state upon clocking.
