ST485CDR Description

Short technical summary and product information.

The STMicroelectronics ST485CDR is an integrated circuit transceiver designed for reliable serial communication. It supports both RS422 and RS485 protocols, operating in a half-duplex mode. This device is capable of handling data rates up to 2.5Mbps, making it suitable for various industrial and commercial applications.

 

With an operating voltage range of 4.75V to 5.25V and an operating temperature range of 0°C to 70°C, the ST485CDR is built for standard operating conditions. It features receiver hysteresis of 70mV, aiding in signal integrity. The transceiver is packaged in an 8-SOIC (Small Outline Integrated Circuit) surface-mount package, measuring 0.154 inches in width.

 

This component is ideal for systems requiring robust serial data transmission over longer distances or in noisy environments. Its half-duplex capability allows for bidirectional communication over a single differential pair, optimizing wiring. The surface-mount design facilitates automated assembly processes.
