SN74AHC273PW

Flip Flops Overview

The SN74AHC273PWR is an octal D-type flip-flop from Texas Instruments' AHC logic family, housed in a 20-TSSOP package. It features positive-edge triggering and a master reset function with non-inverting outputs. The device operates within a supply voltage range of 2 V to 5.5 V, supporting a maximum clock frequency of 110 MHz. Key electrical parameters include a propagation delay of 11 ns at 5 V with 50 pF load, output currents of ±8 mA, and static current of 4 µA. It functions reliably across an industrial temperature range of -40°C to +125°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops on a single chip
• Positive-edge clock triggering mechanism for precise data synchronization
• Master reset functionality to initialize all outputs simultaneously
• CMOS compatible input and output structures ensuring low power consumption

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations in digital systems
• General-purpose storage elements in microprocessor interfaces
• Timing control and state machine design applications

Flip Flops Procurement Notes

Verify the specific ordering suffix to confirm the tape-and-reel packaging format required for automated assembly processes. Ensure the selected variant matches the intended operating voltage and temperature range specifications. Confirm RoHS compliance status if environmental regulations apply to the final product assembly. Cross-reference the manufacturer part number with distributor catalogs to ensure accurate component sourcing and availability.

Flip Flops Selection Notes

Select this component when an octal storage solution with moderate speed and wide voltage flexibility is required. The AHC series offers a balance between performance and power efficiency suitable for general digital logic. Consider the TSSOP-20 package dimensions for PCB layout constraints. Evaluate the 110 MHz clock limit against system timing requirements to ensure adequate signal integrity margins during operation.

Flip Flops Part Context

This device belongs to the SN74AHC273 series of octal D-type flip-flops manufactured by Texas Instruments. It is part of the broader 74AHC logic family, designed to provide high-speed operation with CMOS compatibility. The PWR suffix indicates the specific surface-mount TSSOP-20 package variant, distinguishing it from through-hole or other package options within the same logical family.
