SN74BCT29864BNT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74BCT29864BNT is a 9-bit bidirectional transceiver designed for asynchronous communication between data buses. It utilizes BiCMOS technology to reduce standby current and features power-up high-impedance states. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from 0°C to 70°C. It provides high-level output currents up to -24 mA and low-level output currents up to 48 mA, with propagation delays ranging from 1 ns to 6.1 ns depending on the specific transition.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the active status and lead time directly with Texas Instruments or authorized distributors before finalizing procurement plans. Confirm that the PDIP NT package meets your board layout requirements. Ensure compliance with RoHS standards if applicable to your manufacturing process. Review the latest datasheet revision for any updates to electrical characteristics or recommended operating conditions prior to integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 9-bit bidirectional buffer is required for asynchronous bus interfacing. It is suitable for applications needing functional equivalence to legacy ALS29864 or AMD Am29864A parts. Consider the 0°C to 70°C operating temperature range and the 4.5 V to 5.5 V supply voltage constraints. The high-impedance power-up state makes it appropriate for systems requiring safe initialization without external reset logic.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74BCT series of logic integrated circuits manufactured by Texas Instruments. The BCT family combines BiCMOS technology with standard TTL-compatible logic levels, offering improved speed and lower power consumption compared to older bipolar families. The 29864 variant specifically addresses bidirectional data transfer needs in digital systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The datasheet explicitly states functional equivalence to the SN74ALS29864 and the AMD Am29864A. These parts can be considered direct replacements where pinout and logical functionality must remain identical. Verify that the replacement part meets the same voltage and temperature specifications.
