SN75ALS161DW

Drivers, Receivers, Transceivers Overview

The SN75ALS161DW is an octal bus transceiver from Texas Instruments, designed for high-speed data transmission on single-ended buses. It operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input and output logic levels. The device features three-state outputs and provides a low-level output current of 48 mA with a high-level output current of -5.2 mA. It exhibits a propagation delay of 20 ns and draws a working power supply current of 75 mA. Designed for surface-mount installation, it is housed in a 20-SOIC package and functions reliably across an operating temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Octal configuration providing eight independent bidirectional data channels for efficient bus interfacing.
• Three-state output capability allows direct connection to bus lines without additional interface hardware.
• High drive strength ensures signal integrity over long bus distances with significant capacitive loading.

Drivers, Receivers, Transceivers Applications

• General-purpose bus systems requiring multiple parallel data paths.
• Industrial control networks utilizing RS-422 compatible signaling standards.
• Memory buffer interfaces in computing architectures.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the exact packaging format, as the base part number may correspond to tube or reel configurations depending on the final character. Confirm RoHS compliance status through the manufacturer's official documentation prior to integration. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal transceiver with ALS speed characteristics and TTL compatibility is required. Compare against standard LS series parts if lower power consumption is critical, noting the trade-off in switching speed. Verify that the 20-SOIC footprint aligns with the PCB layout constraints and that the 48 mA drive current meets the bus termination requirements.

Drivers, Receivers, Transceivers Part Context

This device belongs to the SN75ALS161 series of octal bus transceivers. It serves as a high-performance alternative to older LS-series counterparts, offering faster propagation delays while maintaining pin-to-pin compatibility with standard logic families. The DW suffix indicates a plastic small-outline package suitable for automated surface-mount assembly processes.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the SN75160BDWR. Verify functional equivalence and package compatibility before substitution.
