SN74ALS273DWR

Flip Flops Overview

The SN74ALS273DWR is an octal D-type flip-flop from the Texas Instruments ALS logic family, housed in a 20-pin SOIC package. It features positive-edge triggering and includes a master reset input. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a propagation delay of 15 ns at 5 V with 50 pF load, a maximum clock frequency of 35 MHz, and static current consumption of 20 mA. Output drive capabilities are specified as -2.6 mA for high level and 24 mA for low level.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type storage elements within a single integrated circuit.
• Positive-edge triggering mechanism ensures data capture occurs specifically on the rising edge of the clock signal.
• Integrated master reset function allows synchronous clearing of all outputs to a low state.
• Non-inverting output polarity maintains logical consistency between input data states and resulting output levels.

Flip Flops Applications

• Parallel-to-serial data conversion circuits requiring stable latching
• General-purpose digital storage registers in microprocessor systems
• Timing synchronization stages for clock domain crossing

Flip Flops Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging format, as indicated by the 'W' designation. Ensure compatibility with standard surface-mount assembly processes for the SOIC-20 footprint. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated assemblies.

Flip Flops Selection Notes

Select this component when an octal register with fast switching speeds is required within the ALS logic family constraints. Consider the 15 ns propagation delay and 35 MHz clock limit against system timing requirements. Evaluate the 20 mA static current draw against power budget limitations compared to lower-power alternatives like the LVC series.

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 over standard TTL while maintaining lower power consumption than earlier LS families. The device is designed for general-purpose digital applications requiring reliable data storage.

Flip Flops Replacement Considerations

SN74ALS273DW is the non-reel equivalent version. SN74ALS273DR serves as a direct substitute from other manufacturers utilizing compatible pinouts and electrical characteristics within the same logic family specifications.
