ST26C31BDR

Product Overview

STMicroelectronics ST26C31BDR is a surface-mount driver device described as a 4/0 transceiver in a 16-SO package. The device supports RS422 and RS485 protocols and provides four driver channels with no receiver channels. It operates from a supply voltage range of 4.5 V to 5.5 V and is specified for an operating temperature range of -40°C to 85°C. The package is a 16-SOIC with a 0.154 in (3.90 mm) width.

Key Features

• Four driver channels and no receiver channels, as indicated by the 4/0 driver/receiver count.
• Supports RS422 and RS485 protocols.
• Supply voltage range of 4.5 V to 5.5 V.
• Operating temperature range of -40°C to 85°C.
• Surface-mount 16-SOIC package, 0.154 in (3.90 mm) width; supplier device package 16-SO.

Applications

• RS422 or RS485 serial data links requiring driver outputs.
• Embedded systems that operate from 4.5 V to 5.5 V and need multiple driver channels.

Design & Procurement Notes

When selecting this part, confirm that the board requires four driver channels rather than a receiver or combined driver/receiver function, because the supplied 4/0 count indicates drivers only. Verify that the system supply is within 4.5 V to 5.5 V and that the specified operating temperature range of -40°C to 85°C is adequate for the intended use. The surface-mount 16-SOIC package affects footprint, land pattern, and thermal behavior, so check the 0.154 in (3.90 mm) width against the available PCB area and assembly process. The supplied series field is '-', so selection should rely on the listed protocol, driver count, voltage, temperature, and package. The Active status is stated as supplied and should be confirmed against current procurement documentation.
