SN74ALS29863DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS29863DW is a 9-bit 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 from 0°C to 70°C. The device features four output-enable inputs (OEAB1, OEAB2, OEBA1, OEBA2) that control data flow direction or isolation. Propagation delay ranges from 8 ns to 15 ns depending on load capacitance. Output drive capabilities include a maximum low-level output current of 48 mA and a high-level output current of -24 mA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports asynchronous bidirectional data transmission between A and B buses
• Provides flexible timing control through multiple independent output-enable inputs
• Ensures power-up high-impedance state for safe initialization

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous two-way communication between data buses
• Bus-oriented memory architectures requiring bidirectional data transfer
• Control-function implementations demanding flexible timing management

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DW' corresponds to the plastic small-outline package with 24 pins. Confirm RoHS compliance status and lead finish details via the latest packaging information addendum. Ensure the procurement matches the active production status and verify the tube quantity per carrier if applicable.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 9-bit wide bidirectional interface is required. The ALS logic family offers higher speed than standard TTL while maintaining compatible voltage levels. Verify that the application requires the specific four-input enable configuration for precise bus arbitration and isolation control.
