74ABT273CMSAX

Flip Flops Overview

The onsemi 74ABT273CMSAX is an octal D-type flip-flop belonging to the ABT logic series, designed for high-speed digital applications. It features a single element with eight bits per element and utilizes a 20-SSOP surface-mount package. The device operates within a supply voltage range of 4.5V to 5.5V and supports a maximum clock frequency of 200 MHz. Key electrical parameters include a propagation delay of 5ns at 5V with 50pF load, output currents of 32mA (high) and 64mA (low), and a static current of 50 µA. It functions as a positive-edge triggered, non-inverting register with standard functionality.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture providing eight-bit data storage capability in a single integrated circuit element.
• High-speed performance enabled by the ABT logic series, supporting clock frequencies up to 200 MHz.
• Positive-edge triggering mechanism ensures precise data capture synchronized with the rising clock edge.
• Non-inverting output polarity maintains signal integrity without logical inversion during data transfer.

Flip Flops Applications

• High-speed parallel data buffering and latching in digital communication systems.
• Register stages in microprocessor-based memory interfaces and bus architectures.
• Data acquisition systems requiring fast sampling and storage of multiple input lines.
• Industrial control logic where rapid state retention and high-frequency operation are required.

Flip Flops Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm that the specific suffix 'CMSAX' corresponds to the tape-and-reel packaging format intended for automated assembly processes. Ensure compliance with RoHS directives and check for any recent product change notifications affecting pinout or electrical characteristics before finalizing procurement plans.

Flip Flops Selection Notes

Select this component when design requirements demand high-speed octal registration with strong drive capabilities. The ABT series offers superior speed compared to standard CMOS alternatives while maintaining low power consumption. Consider the 20-SSOP package dimensions for PCB layout constraints. Evaluate the 5ns propagation delay against system timing budgets to ensure signal integrity at operating frequencies near the 200 MHz limit.

Flip Flops Part Context

This part belongs to the broader 74ABT family of advanced bipolar-transistor technology logic devices, known for balancing speed and power efficiency. It serves as a functional equivalent to other octal D-flip-flops but distinguishes itself through its specific switching characteristics and package configuration. The 74ABT273 variant is widely recognized in legacy and modern mixed-signal designs for reliable high-performance data handling.

Flip Flops Replacement Considerations

Public confirmed substitute part numbers include SN74ABT374ADBR, SN74ABT374APW, and SN74ABT374APWR from Texas Instruments. These alternatives offer comparable octal D-type flip-flop functionality within the same logic family specifications.
