SN74F622DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F622DW is an octal bus transceiver manufactured by Texas Instruments, designed for high-speed data transfer applications. It features eight D-type flip-flops with tri-state outputs and bus-hold circuitry to maintain stable logic levels during idle states. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input types. Packaged in a 20-pin SOIC (DWR) format suitable for surface mount technology, it ensures reliable performance across industrial temperature ranges.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-20 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management aligns with the specified operating temperature range for the target application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring robust bus isolation and defined idle states via bus-hold features. Compare propagation delay specifications against system timing requirements. Evaluate pin compatibility with existing PCB footprints if replacing legacy components from other logic families.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74F series of fast logic devices, optimized for speed-critical digital circuits. It complements other octal transceivers like the SN74F624 but distinguishes itself through specific bus-hold implementation. The DW package variant offers a standard footprint compatible with automated assembly processes widely used in modern electronics manufacturing.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the SN74F624DW for similar functionality with potential pinout variations. Cross-reference with SN74AS622DW for enhanced speed performance in compatible packages. Verify electrical characteristics match before swapping to ensure signal integrity.
