SN74HC273ANS

Flip Flops Overview

The SN74HC273ANS is an octal D-type flip-flop from the Texas Instruments HC logic family, housed in a 20-pin SOIC package. It features eight independent D-type storage elements with positive-edge triggering and a master reset input. The device operates within a supply voltage range of 2.0 V to 6.0 V, supporting clock frequencies up to 32 MHz. Key electrical characteristics include a maximum propagation delay of 25 ns at 6 V with 50 pF load, and output drive currents of ±5.2 mA. It is designed for applications requiring non-inverting outputs and shared clock/reset signals.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single package
• Positive-edge triggered data storage with synchronous operation
• Master reset functionality for initializing all storage elements simultaneously
• Non-inverting output polarity compatible with standard CMOS logic levels

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• General-purpose register banks in digital systems
• State machine implementation requiring multiple synchronized storage bits
• Buffering applications for data latching between logic stages

Flip Flops Procurement Notes

Verify the specific suffix 'ANS' against the manufacturer's current product status, as some sources indicate this variant may be obsolete or superseded by newer revisions. Confirm package compatibility and lead times with authorized distributors, as availability varies significantly across regions. Ensure the selected component matches the required operating temperature range and voltage specifications for your design.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with a master reset is required in a surface-mount SOIC-20 package. It is suitable for designs operating between 2 V and 6 V where propagation delays around 25 ns are acceptable. Consider alternative packages like PW (TSSOP) or DW (SOIC) if pin-out compatibility differs, but verify functional equivalence before substitution.

Flip Flops Part Context

The SN74HC273ANS belongs to the Texas Instruments SN74HC series of high-speed CMOS logic devices. This series is known for low power consumption and wide voltage operation. The 'ANS' suffix typically denotes a specific package type and temperature rating, often associated with industrial or extended ranges depending on the manufacturing revision. It is part of a broader family of octal flip-flops used in complex digital logic applications.

Flip Flops Replacement Considerations

Check for direct replacements such as SN74HC273DW or SN74HC273PWR, which share identical logical functions but differ in package style (SOIC vs TSSOP). Verify that any substitute maintains the same pinout and electrical characteristics, particularly the 25 ns propagation delay and ±5.2 mA drive current, to ensure circuit compatibility.
