SN74ALS273N

Flip Flops Overview

The SN74ALS273N is an octal D-type flip-flop from the Texas Instruments ALS logic series. It features eight positive-edge-triggered D-type flip-flops with a common clear input, housed in a 20-pin PDIP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports through-hole mounting. Key electrical parameters include a propagation delay of 15 ns, a high-level output current of -2.6 mA, and a low-level output current of 24 mA. It functions as a non-inverting TTL logic component suitable for standard digital applications.

Flip Flops Feature Summary

• Contains eight independent positive-edge-triggered D-type flip-flops
• Includes a dedicated master clear input for synchronous reset operations
• Provides non-inverting TTL-compatible outputs for direct interfacing

Flip Flops Applications

• Octal data storage registers
• Parallel-to-serial conversion circuits
• Digital state machine implementation

Flip Flops Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape-and-reel configuration. Ensure the procurement channel provides official datasheets matching the SN74ALS273N designation. Confirm RoHS compliance status and manufacturing origin details prior to finalizing acquisition orders for quality assurance.

Flip Flops Selection Notes

Select this component when requiring octal storage with ALS speed characteristics and TTL interface compatibility. Consider the 20-pin PDIP form factor for prototyping or through-hole assembly requirements. Evaluate power consumption and drive strength specifications against system load requirements before integration into the design.

Flip Flops Part Context

This part belongs to the SN74ALS273 family of octal D-type flip-flops manufactured by Texas Instruments. It represents the Advanced Low-power Schottky (ALS) technology variant, offering improved speed and power efficiency compared to earlier LS series counterparts while maintaining pin-out compatibility.

Flip Flops Replacement Considerations

SN74ALS273NSR serves as a surface-mount alternative in the same logic family.
