74ABT273CSC

Flip Flops Overview

The Fairchild Semiconductor 74ABT273CSC is an octal D-type flip-flop belonging to the ABT logic series. It features eight edge-triggered D-type flip-flops with individual inputs and non-inverting outputs, controlled by a common buffered clock and master reset. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 6.8 ns, a high-level output current of -32 mA, and a low-level output current of 64 mA. It is housed in a SOP-20 package and supports a commercial operating temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Contains eight edge-triggered D-type flip-flops with individual data inputs and Q outputs.
• Utilizes a common buffered Clock (CP) input for synchronized data capture.
• Includes a buffered asynchronous Master Reset (MR) input to clear all flip-flops simultaneously.

Flip Flops Applications

• Registering data in microprocessor-based systems
• Memory interface buffering applications
• General-purpose parallel data storage

Flip Flops Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements prior to procurement. Ensure that the SOP-20 package variant matches the design footprint. Request official datasheets and quality certificates to validate performance specifications against project requirements.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with high drive capability is required. The ABT series offers superior speed compared to standard AC/ACT families while maintaining CMOS compatibility. Verify that the 4.5 V to 5.5 V supply voltage aligns with the system power rail. Ensure the SOP-20 package dimensions fit the PCB layout constraints.

Flip Flops Part Context

This part belongs to the 74ABT family of high-speed BiCMOS logic devices. It serves as a digital storage element within larger integrated circuit designs. The 74ABT273CSC specifically provides octal configuration, distinguishing it from single or dual flip-flop variants. It complements other ABT components like bus drivers and latches in complex digital logic architectures.

Flip Flops Replacement Considerations

The SN74ABT273N from Texas Instruments is a confirmed functional substitute offering identical logical operations and pinout compatibility. Both devices share the same ABT series characteristics and electrical specifications. Verify package type differences if transitioning between SOP and PDIP formats.
