SN74HC273APW

Flip Flops Overview

The SN74HC273APWR is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the HC logic family. It features eight independent data inputs and non-inverting outputs with a common clock and master reset. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a propagation delay of 160 ns, high-level output current of -5.2 mA, and low-level output current of 5.2 mA. It is housed in a TSSOP-20 surface-mount package.

Flip Flops Feature Summary

• Contains eight edge-triggered D-type flip-flops with independent data inputs and non-inverting outputs
• Features a common clock input for synchronized data latching across all channels
• Includes a master reset function that forces all outputs to a low state independently of clock or data inputs

Flip Flops Applications

• Register applications requiring parallel data storage
• Shift register configurations for serial-to-parallel conversion
• State machine implementations in digital control systems

Flip Flops Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for the intended manufacturing process. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Flip Flops Selection Notes

Select this component when designing circuits requiring multiple synchronized storage elements with a shared control interface. The HC series offers compatibility with standard CMOS logic levels and provides sufficient drive current for moderate loads. Consider the TSSOP-20 package constraints regarding thermal management and PCB space availability during layout planning.

Flip Flops Part Context

This device is part of the SN74HC273 family of octal D-type flip-flops. Variants such as SN74HC273DWR utilize SOIC packaging, while automotive-grade versions like SN74HC273QDWRQ1 offer extended temperature ranges and AEC-Q100 qualification. All variants share the core logical functionality but differ in physical packaging and environmental ratings.

Flip Flops Replacement Considerations

Direct substitutes include SN74HC273DWR for alternative SOIC-20 packaging and MC74HC273ADWR2G from onsemi. Verify pinout compatibility and electrical characteristics match the original design requirements before substitution.
