ST26C32ABTR

Product Overview

The ST26C32ABTR from STMicroelectronics is a surface-mount receiver intended for RS422 and RS423 serial data interfaces. The device is specified for a 4.5V to 5.5V supply range and supports a data rate up to 20Mbps. It is supplied in a 16-TSSOP package with a 4.40mm width, and its operating temperature range is -40°C to 85°C. The receiver includes 60mV of hysteresis and is configured as a 0/4 receiver, meaning it provides receive channels without transmit drivers. The device is intended for receive-side interface functions rather than full transceiver operation.

Key Features

• Receiver-only device with 0/4 driver/receiver configuration
• Supports RS422 and RS423 protocols
• Rated data rate of 20Mbps
• Operates from a 4.5V to 5.5V supply
• 16-TSSOP surface-mount package with 4.40mm body width
• Operating temperature range of -40°C to 85°C
• 60mV receiver hysteresis
• Supplied lifecycle status: Active

Applications

• Receiving RS422 or RS423 serial data in equipment interconnects where a receive-only channel is required
• Receiving serial data in control or instrumentation interface links

Design & Procurement Notes

Designers should confirm that the application requires a receiver-only 0/4 configuration, since the part does not provide transmit drivers according to the supplied data. Board layout and reflow profiles should account for the 16-TSSOP surface-mount package and 4.40mm body width. The 16-TSSOP designation should be checked against the available package drawing for pin numbering. The 4.5V to 5.5V supply range and -40°C to 85°C operating temperature range should be checked against system power and environmental requirements. The 20Mbps data rate and 60mV hysteresis may help with timing and noise margin evaluation, but protocol compatibility with RS422 and RS423 remains the primary selection factor. The supplied lifecycle status is Active.
