SN74AHC273DW

Flip Flops Overview

The SN74AHC273DW is an octal D-type flip-flop from the Texas Instruments AHC logic series, housed in a 20-pin SOIC package. It features eight non-inverting outputs with a master clear function. The device operates within a supply voltage range of 2 V to 5.5 V and supports a maximum clock frequency of 208 MHz. Key electrical parameters include a propagation delay of 17.1 ns, high-level output current of -8 mA, and low-level output current of 8 mA. It functions reliably across an operating 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
• Master clear input for synchronous resetting of all eight flip-flops simultaneously
• CMOS-compatible inputs and push-pull outputs ensuring robust signal integrity
• Wide operating voltage range supporting both 2V and 5V system architectures

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register storage elements in digital logic systems
• Timing and synchronization applications requiring multiple bit storage
• General-purpose memory buffer implementations

Flip Flops Procurement Notes

Verify component authenticity through authorized channels due to widespread availability of counterfeit logic ICs. Confirm package marking matches the specific SN74AHC273DW designation. Check datasheet revisions for any updates to electrical characteristics or recommended soldering profiles. Ensure environmental compliance documentation aligns with project requirements before finalizing procurement decisions.

Flip Flops Selection Notes

Select this component when designing systems requiring multiple synchronized storage elements with fast switching speeds. The AHC series offers superior performance compared to standard HC logic while maintaining CMOS compatibility. Consider the 20-pin SOIC package constraints for PCB layout and thermal management. Evaluate power consumption requirements as the device draws minimal static current but exhibits dynamic power usage proportional to clock frequency and load capacitance.
