SN74AHCT273PWR-P

Flip Flops Overview

The SN74AHCT273PWR-P is an octal D-type flip-flop from the Texas Instruments 74AHCT logic family, housed in a 20-pin TSSOP package. It features eight positive-edge-triggered D-type flip-flops with single rail outputs and a direct clear input. The device operates within a supply voltage range of 4.5 V to 5.5 V. It supports a maximum clock frequency of 45 MHz at nominal supply conditions. The component exhibits a propagation delay of 7.4 ns and provides output drive currents of -8 mA (high) and 8 mA (low). It functions reliably across an operating temperature range of -40°C to +125°C.

Flip Flops Feature Summary

• Integrates eight independent D-type flip-flops with positive-edge triggering for parallel data storage.
• Includes a dedicated direct clear input to asynchronously reset all flip-flops to a low state.
• Ensures robust latch performance exceeding 250 mA, compliant with JESD 17 standards.
• Maintains TTL-compatible input voltage levels while utilizing CMOS output structures.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations
• General-purpose memory storage elements
• Timing and control signal latching

Flip Flops Procurement Notes

Verify the specific suffix 'PWR-P' against the manufacturer's official documentation to confirm pinout and electrical characteristics match standard SN74AHCT273PWR specifications. Ensure the component meets RoHS compliance requirements and check for moisture sensitivity level ratings appropriate for surface-mount assembly processes. Confirm availability through authorized distributors to avoid counterfeit parts.

Flip Flops Selection Notes

Select this component when designing systems requiring high-density octal storage with TTL-compatible inputs. It is suitable for applications needing fast switching speeds up to 45 MHz and wide operating temperature ranges. Consider the TSSOP-20 package constraints for PCB layout. Compare against SN74HCS273 or SN74HC273 variants if different voltage levels or Schmitt trigger inputs are required instead of standard CMOS inputs.

Flip Flops Part Context

This part belongs to the Texas Instruments 74AHCT series, which bridges high-speed CMOS technology with TTL compatibility. The SN74AHCT273 variant specifically provides octal D-type flip-flops with clear functionality. The '-PWR' suffix indicates the TSSOP-20 tape-and-reel packaging format, while '-P' may denote a specific manufacturing lot or regional variant requiring datasheet verification.

Flip Flops FAQ

Does the SN74AHCT273PWR-P have inverted outputs?

No, the device provides non-inverting single rail outputs for each of the eight flip-flops.

What is the function of the clear input?

The clear input is active-low and directly resets all eight flip-flops to a low state asynchronously, regardless of the clock signal.
