SN74AS823ADW

Flip Flops Overview

The SN74AS823ADW is a single D-type flip-flop containing nine bits, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and features positive-edge triggering with a master reset function. The device provides non-inverting tri-state outputs capable of sourcing 24mA and sinking 48mA. Maximum propagation delay is 13ns at 5V with 50pF load. Static current consumption is 80mA. It is housed in a 24-SOIC package and supports an operating temperature range of 0°C to 70°C.

Flip Flops Feature Summary

• Contains nine independent D-type flip-flops with positive-edge clock triggering
• Provides non-inverting tri-state outputs for bus-oriented applications
• Includes a master reset input to initialize all flip-flops simultaneously

Flip Flops Applications

• High-speed data storage registers
• Bus interface circuits
• Parallel-to-serial conversion modules

Flip Flops Procurement Notes

Verify the specific suffix 'ADW' against official Texas Instruments documentation to confirm the SOIC package type and commercial temperature grade. Ensure compatibility with existing 5V logic levels and check for end-of-life status or alternative sourcing options due to potential discontinuation of this AS series component.

Flip Flops Selection Notes

Select this component when requiring high-speed 9-bit storage with tri-state output control. Compare against SN74ALS823 variants for lower power requirements or SN74LVC823 for lower voltage operation. Verify that the 80mA static current draw fits within the system's thermal and power budget constraints.

Flip Flops Part Context

This part belongs to the Texas Instruments 74AS (Advanced Schottky) logic family, known for high speed but higher power consumption compared to ALS or LVC families. It serves as a specialized storage element within digital systems requiring fast data latching and high drive capability on shared buses.

Flip Flops Replacement Considerations

SN74AS823AN: Identical functionality in a PDIP package. SN74ALS823: Lower power alternative with similar performance. SN74LVC823: Lower voltage compatible option.
