DS36954VX/NOPB

Overview

The DS36954VX/NOPB is a quad line transceiver manufactured by Texas Instruments, formerly National Semiconductor. It supports RS-422 and RS-485 communication standards with a data rate of up to 10 Mb/s. The device integrates one driver and four receivers in a single package. It operates at a fixed supply voltage of 5 V with a typical operating current of 500 uA. The component is housed in a PDSO20 (SOIC-20) package and functions in half-duplex mode. It features an active shutdown mode for power reduction and includes individual driver enables.

Feature Summary

• Integrates four receivers and one driver for multi-drop bus applications
• Supports high-speed data transmission up to 10 Mb/s
• Includes active shutdown mode to minimize power consumption
• Features individually enabled drivers for flexible bus control

Applications

• RS-485 multi-drop communication networks
• RS-422 point-to-point or multi-point links
• Industrial automation bus systems
• Building automation control networks

Procurement Notes

Verify the manufacturer designation carefully, as the part originates from National Semiconductor but is now distributed under the Texas Instruments brand. Confirm the specific suffix 'VX' against official datasheets to ensure correct packaging and temperature range specifications. Check for RoHS compliance status and moisture sensitivity levels before integration into production workflows.

Selection Notes

Select this component when designing systems requiring four independent receiver inputs alongside a single transmitter output on a shared bus. Ensure the application environment stays within the specified commercial temperature range. Verify that the 5 V supply voltage aligns with the system's power architecture and that the 10 Mb/s speed meets the network latency requirements.

Part Context

This device belongs to the DS3695 series of interface ICs designed for robust differential signaling. It serves as a bridge between microprocessor-based systems and industrial communication buses. The transition from National Semiconductor to Texas Instruments means documentation may reference either entity, but the electrical characteristics remain consistent across the product lineage.

Replacement Considerations

The DS36954MX/NOPB is a documented alternative within the same family, offering similar quad receiver functionality. Verify pin compatibility and package dimensions before substitution. Other variants in the DS3695 series may offer different driver counts or temperature ranges.
