SN74AS763DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AS763DWR is an octal buffer and line driver manufactured by Texas Instruments, belonging to the 74AS logic series. It features open-collector outputs and is housed in a 20-SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a working temperature range of 0°C to 70°C. Propagation delay is specified at 9 ns, with low-level output current capability of 15 mA and high-level output current of -24 mA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal configuration providing eight independent buffer channels
• Open-collector output structure suitable for wired-OR applications
• High-speed AS logic family performance characteristics

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented systems requiring signal buffering
• Line driving for high-capacitance loads
• Wired-OR logic implementation in digital circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape-and-reel packaging format intended for surface-mount assembly. Confirm RoHS compliance status through the official datasheet or manufacturer documentation prior to procurement. Ensure the open-collector output type aligns with the pull-up resistor requirements of the target circuit design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed buffering with open-collector outputs is required within a 5V logic environment. Compare propagation delay and drive strength against other 74AS variants if tighter timing constraints exist. Verify that the SOIC-20 package dimensions fit the available PCB footprint and thermal management strategy.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74AS (Advanced Schottky) logic family, known for improved speed over standard TTL. The SN74AS763 serves as an octal buffer variant, distinct from flip-flops or latches in the same package lineup. It complements other bus interface components like the SN74AS373 latch.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74AS763DR is a direct equivalent with identical electrical specifications and pinout. SN74AS763N offers the same functionality in a DIP package. Cross-reference with SN54AS763 for military-grade temperature ranges if applicable.
