DS3691M/NOPB

Overview

The DS3691M/NOPB is a low-power Schottky TTL line driver manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range of 0°C to +70°C. The device provides dual RS-422 differential line drivers or quad RS-423 single-ended line drivers, selectable via a mode control pin. It features TRI-STATE outputs with high source and sink current capability, short circuit protection for both source and sink outputs, and 100Ω transmission line drive capability. Input currents are low at 40 μA typical, while supply current reaches 30 mA maximum in RS-422 mode.

Feature Summary

• Configurable operation as dual RS-422 differential drivers or quad RS-423 single-ended drivers via a dedicated mode select pin
• TRI-STATE output capability allowing bus sharing and system flexibility
• Internal short circuit protection safeguards the device against output faults
• External capacitor connection allows rise time control to suppress near-end crosstalk

Applications

• RS-422 point-to-point communication interfaces
• Fully loaded RS-422 multipoint networks
• RS-423 single-ended data transmission systems

Procurement Notes

Verify component authenticity through authorized channels. Confirm package integrity upon receipt. Check datasheet specifications against design requirements. Ensure proper ESD handling during storage and assembly. Review revision history for any parameter updates.

Selection Notes

Select this component for applications requiring RS-422 or RS-423 compliance. Verify that the 0°C to +70°C temperature range meets environmental needs. Consider the SOIC-16 package dimensions for PCB layout. Evaluate power consumption limits against available supply rails.

Part Context

This device belongs to the DS3691 family of line drivers from Texas Instruments. It serves as a robust interface solution for serial communication standards. The NOPB suffix indicates lead-free construction compliant with RoHS directives. It offers a pin-compatible alternative to older generation drivers.
