SD317+

Drivers, Receivers, Transceivers Overview

The SD317+ is a single full-duplex transceiver manufactured by Analog Devices Inc./Maxim Integrated. It supports EIA/TIA-232-F (RS-232) communication standards and operates with a single +5V power supply. The device integrates two drivers and two receivers, providing signal conversion between RS-232 levels and TTL/CMOS logic levels. It features low supply current consumption and includes protection against input voltages exceeding ±30V. The component is housed in a standard small outline package suitable for surface mount applications.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual drivers and dual receivers for full-duplex data transmission
• Operates directly from a single +5V power supply without requiring negative voltage generation
• Provides robust input protection against excessive voltages up to ±30V
• Ensures compatibility with standard RS-232 communication protocols

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring serial communication interfaces
• Modem interfacing and data transmission equipment
• Point-of-sale terminals and barcode scanners
• Medical instrumentation with serial data ports

Drivers, Receivers, Transceivers Procurement Notes

Verify the exact suffix designation (+ or -) to confirm RoHS compliance status, as the base part number may have variations. Confirm the package type matches the target PCB footprint, typically SOIC or DIP variants. Check for obsolescence notices from Analog Devices, as older interface components may be subject to discontinuation. Ensure the operating temperature range meets the specific environmental requirements of the end application.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a simple, low-cost solution for bidirectional RS-232 communication is required. It is suitable for designs where space is limited but high-speed data rates are not critical. Consider the pin count and package size relative to available board real estate. Verify that the ±30V input protection is sufficient for the expected line conditions in the specific deployment environment.

Drivers, Receivers, Transceivers Part Context

The SD317+ belongs to the broader family of Maxim Integrated RS-232 transceivers designed for reliable serial communication. These devices are widely used in legacy and industrial systems where standard voltage level shifting is necessary. The product line emphasizes ease of use and minimal external component requirements, making it a common choice for embedded serial port implementations.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include the MAX3232 series for enhanced performance or the MAX3237 for lower voltage operation. Other compatible alternatives within the same family include the MAX3243 or MAX3248 depending on the required driver/receiver count. Verify pin-to-pin compatibility before substitution to ensure seamless integration into existing hardware designs.
