Product Description
STMicroelectronics ST485ECDR is an industry-grade line transceiver IC designed to meet RS-422 and RS-485 communication standards. It supports 3-state output and is mounted on a compact 8-Pin Small Outline IC (SOIC) package suitable for surface mounting. The device operates reliably over a wide supply voltage range of 5V to 7V, making it versatile for industrial and commercial electronic interface applications.
This transceiver features a single channel with differential input types and a 3-state output to ensure efficient line communication and signal isolation. Its low supply current of approximately 300 microamps contributes to low power consumption, which is critical in embedded and portable systems.
The operational temperature range spans from -55°C to 125°C, allowing the transceiver to function reliably in harsh environments and demanding industrial settings. With a maximum propagation delay of 130 nanoseconds at capacitive load, the device maintains fast and stable data transmission.
The compact dimensions of 5mm length, 4mm width, and 1.75mm height in SOIC format facilitate high-density PCB layouts. Compliance with RS-422, RS-485, and IEC-1000-4-2 standards ensures electromagnetic compatibility and resilience against electrostatic discharge.
This line transceiver is ideal for applications requiring robust serial communication lines such as industrial automation, control systems, instrumentation, and networking equipment. It provides dependable performance for differential signal transmission over longer distances.
Operates on 5V to 7V power supply. Provides single differential channel with 3-state output. Surface mount 8-pin SOIC package for compact PCB design. Low power consumption with 300μA supply current. Wide temperature tolerance from -55°C to 125°C.
Fast propagation delay time of 130ns ensures swift communication. Standards compliant: RS-422, RS-485, IEC-1000-4-2. Maximum output current is 4mA for high and low states. Suitable for industrial, manufacturing, and telecommunications applications.
