SN74ALS29863DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS29863DWR is a 9-bit bus transceiver designed for asynchronous two-way communication between data buses. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range of 0°C to 70°C. The device features three-state outputs with high-level output current of -24 mA and low-level output current of 48 mA. Propagation delay is typically 15 ns at 300 pF load and 8 ns at 50 pF load. Enable/disable times are characterized up to 23 ns. It is housed in a 24-pin Small-Outline (DW) package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DWR' against the manufacturer's latest documentation to confirm the SOIC package type and tube packaging quantity. Confirm RoHS compliance status and lead finish details directly from the official datasheet or package addendum before procurement, as these specifications define the physical and environmental characteristics of the component.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 9-bit wide bus interface is required rather than standard 8-bit configurations. Ensure the design accommodates the four separate output-enable inputs for precise timing control. Verify that the system voltage remains within the 4.75 V to 5.25 V range and that the thermal environment stays within the specified 0°C to 70°C operational limits.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments SN74ALS series of logic components. It is functionally equivalent to AMD’s AM29863. The ALS series offers advanced low-power Schottky performance, providing faster switching speeds compared to standard LS logic while maintaining lower power consumption. This specific part number represents the plastic small-outline variant of the 9-bit transceiver.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74ALS29863 is functionally equivalent to AMD’s AM29863. When substituting, verify pin compatibility and electrical characteristics such as propagation delay and output drive strength to ensure seamless integration into existing designs.
