SN74AHCT273PWR

Flip Flops Overview

The SN74AHCT273PWR is an octal D-type flip-flop from the Texas Instruments 74AHCT series, housed in a 20-pin TSSOP package. It features a master reset function and positive-edge triggering with non-inverting outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a maximum clock frequency of 45 MHz, a propagation delay of 9.2 ns at 5 V with 50 pF load capacitance, and output drive currents of ±8 mA. It supports a wide operating temperature range from -40 °C to +85 °C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single package
• CMOS-compatible inputs allowing direct interfacing with CMOS logic systems
• Master reset functionality for synchronous clearing of all flip-flop states
• Positive-edge triggering mechanism ensuring precise data capture on clock transitions

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations for data storage and transfer
• General-purpose memory elements in digital control systems
• Timing and synchronization logic in microprocessor-based designs

Flip Flops Procurement Notes

Verify that the component matches the exact SN74AHCT273PWR designation to ensure compatibility with AHCT logic levels. Confirm the TSSOP-20 package type and lead-free RoHS compliance status prior to integration. Cross-reference the manufacturer datasheet for specific handling requirements regarding moisture sensitivity level 1 classification during surface mount assembly processes.

Flip Flops Selection Notes

Select this component when designing systems requiring high-density octal storage with CMOS input compatibility. It is suitable for applications needing moderate speed performance up to 45 MHz with standard 5 V logic interfaces. Consider alternative packages like SOIC if board space constraints differ, or verify thermal requirements against the specified -40 °C to +85 °C operating range for industrial environments.

Flip Flops Part Context

This part belongs to the Texas Instruments 74AHCT family, which bridges high-speed CMOS technology with TTL-compatible input thresholds. The SN74AHCT273 variant specifically provides octal storage capabilities. It serves as a standard solution for parallel data latching in mixed-voltage digital systems where interface compatibility between CMOS and legacy TTL standards is required.
