SN74HCT273APWR

Flip Flops Overview

The SN74HCT273APWR is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the HCT logic series. It features eight positive-edge-triggered D-flip-flops with a master reset function and non-inverting outputs. The device operates within a supply voltage range of 4.5V to 5.5V and utilizes a 20-TSSOP surface-mount package. Key electrical parameters include a maximum propagation delay of 29ns at 5.5V with 50pF load, a clock frequency of 37 MHz, and static current of 8 µA.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single integrated circuit
• Master reset functionality allows simultaneous clearing of all flip-flop states
• Positive-edge triggering ensures data capture occurs on the rising edge of the clock signal
• Non-inverting output structure maintains logical consistency between input and output states

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations for data storage and transfer
• Register banks for temporary data holding in digital systems
• Timing synchronization and state retention in microcontroller interfaces

Flip Flops Procurement Notes

Verify the specific suffix 'A' against the official manufacturer datasheet to confirm it denotes a valid production variant or specific qualification level distinct from standard SN74HCT273PWR. Ensure the component matches the required RoHS compliance status and moisture sensitivity level (MSL) specifications for your assembly process. Confirm availability through authorized distributors to avoid counterfeit risks.

Flip Flops Selection Notes

Select this component when designing 5V logic systems requiring high-density octal storage with fast switching capabilities. The HCT series ensures compatibility with standard TTL inputs while offering CMOS low power consumption. Consider the 20-TSSOP package dimensions for PCB layout constraints and verify that the 37 MHz clock limit meets the system's timing requirements.

Flip Flops Part Context

This part belongs to the widely adopted 74HCT family of logic ICs, designed for operation in 5V environments with TTL-compatible input thresholds. The SN74HCT273 serves as a fundamental building block for sequential logic design, providing reliable data latching capabilities. Its integration into the TSSOP package facilitates automated surface-mount assembly processes.
