74ABT273CMSA

Flip Flops Overview

The Fairchild Semiconductor 74ABT273CMSA is an octal D-type flip-flop belonging to the ABT logic series. It features eight positive edge-triggered inputs and single-ended outputs housed in a 20-lead SSOP package. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a typical propagation delay of 6.8 ns. It provides high drive capability with a low-level output current of 64 mA and a high-level output current of -32 mA. The component supports surface mount installation and functions reliably across an operating temperature range from -40 °C to +85 °C.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with separate inputs for each stage
• Positive edge-triggered clocking mechanism for data capture
• High-current output drivers supporting bus-oriented applications
• Glitch-free operation during power-up and power-down cycles

Flip Flops Applications

Flip Flops Procurement Notes

Verify that the specific suffix CMSA corresponds to the SSOP-20 package variant when sourcing replacements. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors, as environmental regulations vary by region and production batch. Ensure the procurement channel provides traceable manufacturing records to guarantee component authenticity and quality standards.

Flip Flops Selection Notes

Select this component for designs requiring high-speed data latching with strong output drive capabilities. The ABT series offers superior performance compared to standard TTL or AC families. Consider the SSOP-20 package constraints regarding thermal dissipation and PCB space. Verify that the system voltage aligns strictly with the 4.5 V to 5.5 V operational window to ensure reliable switching characteristics.

Flip Flops Part Context

This part belongs to the widely adopted 74ABT family of high-speed CMOS logic devices. It serves as a direct functional equivalent to other octal D-type flip-flops like the 74ABT374, though pinout configurations may differ. The ABT series bridges the performance gap between older bipolar technologies and modern CMOS solutions, offering speed comparable to ALS while maintaining low power consumption.

Flip Flops Replacement Considerations

The 74ABT374CMSA is a confirmed substitute part number within the same product line.
