DS36954M/NOPB

Overview

The DS36954M/NOPB is a quad differential bus transceiver manufactured by Texas Instruments, operating within the DS36954 series. It supports RS-422 and RS-485 communication standards with a data rate of up to 10 Mb/s. The device features one driver and four receivers in a 20-SOIC package. It operates on a single 5 V supply with a maximum operating current of 500 uA. The component supports half-duplex communication and includes a shutdown mode for power reduction. It functions reliably within an ambient temperature range of 0°C to +70°C.

Feature Summary

• Supports multipoint communication via RS-485 and point-to-point links via RS-422
• Integrates four receivers and one driver for efficient bus interfacing
• Includes individual driver enables and active-under-shutdown receiver functionality

Applications

• Industrial automation control systems
• Building automation networks
• Multipoint data transmission buses

Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Confirm the specific suffix 'NOPB' indicates lead-free compliance and RoHS status. Ensure the SOIC-20 package matches the target PCB footprint. Check for moisture sensitivity level requirements during storage and handling procedures before assembly.

Selection Notes

Select this component when a quad receiver configuration is required alongside a single driver for RS-485 or RS-422 applications. Consider the 10 Mb/s speed limit and 5 V operating voltage constraints. Evaluate the thermal performance within the 0°C to +70°C commercial temperature range against system environmental conditions.

Part Context

This part belongs to the DS3695x family of high-speed differential transceivers. It shares functional similarities with other members like the DS3695AM but differs in pin count and channel configuration. The transition from National Semiconductor to Texas Instruments means datasheets may reference either entity depending on the publication date.
