CD74ACT273SM96

Overview

The CD74ACT273SM96 is an octal D-type flip-flop from the Texas Instruments ACT logic series. It features a positive-edge trigger mechanism and non-inverting outputs. The device operates within a supply voltage range of 1.5 V to 5.5 V. Key electrical parameters include a propagation delay of 13.5 ns, with high-level output current of -24 mA and low-level output current of 24 mA. It supports TTL input levels and CMOS output types. The component is housed in an SSOP-20 surface-mount package and functions across an industrial temperature range of -55°C to +125°C.

Feature Summary

• Integrates eight independent D-type flip-flops with positive-edge triggering for synchronous data storage.
• Features a master reset input that asynchronously clears all flip-flop outputs to a low state.
• Provides high-drive capability with symmetric output currents suitable for direct interface to TTL loads.

Applications

• Parallel-to-serial data conversion circuits
• Register files in microprocessor-based systems
• Shift register configurations for data buffering

Procurement Notes

Verify the specific suffix 'M96' against the manufacturer's latest datasheet to confirm packaging details and RoHS compliance status. Ensure the design accommodates the specified operating temperature range and supply voltage requirements. Confirm pinout compatibility if replacing legacy components. Check for any recent product change notifications regarding material composition or manufacturing site changes.

Selection Notes

Select this component when high-speed operation with moderate drive strength is required in a compact surface-mount form factor. The ACT series offers a balance between speed and power consumption compared to standard HC or HCT logic. Consider the 13.5 ns propagation delay for timing constraints. The wide supply voltage range allows flexibility in system power design, while the SSOP-20 package aids in space-constrained PCB layouts.

Part Context

This part belongs to the CD74ACT273 family of octal D-type flip-flops manufactured by Texas Instruments. It is part of the broader 74ACT logic line, which bridges the performance gap between AC and ALST logic families. The device is designed for high-speed digital applications requiring reliable data latching and transfer capabilities in complex integrated circuits.

Replacement Considerations

Compatible substitutes include CD74ACT273E (PDIP) and CD74ACT273M96 (SOIC). Verify pinout and electrical specifications match before substitution.
