Product Description

STMicroelectronics ST485ABDR is a single-channel, 3-state line transceiver IC designed for robust RS 485 and similar interface applications. Operating from a low voltage range between 4.5 V and 7 V, it features a differential input and 3-state output capable of high data rates exceeding 30 Mbps. The device offers advanced protective features, including current limiting and thermal shutdown to safeguard against driver overload conditions.

The ST485ABDR ensures reliable performance across a wide industrial temperature range from -40°C to +85°C making it suitable for demanding industrial, manufacturing, and communication systems. It provides ±4 kV electrostatic discharge protection, enhancing its ruggedness in harsh environments.

Designed for surface mounting in a compact 8-pin Small Outline (SO) package with dimensions 9.8 mm (L) x 8.8 mm (W) x 1.75 mm (H), this transceiver is ideal for space-constrained electronic designs. It maintains high impedance output during 3-state operation or when power is off, preventing signal interference.

The device includes a typical input hysteresis of 70 mV to minimize noise sensitivity and sustain signal integrity on the communication lines. Its compliance with JEDEC JESD97 standard reflects stringent industry quality and reliability benchmarks.

Operates from single 5 V supply with low maximum supply current of 5 mA. Provides current limiting and thermal shutdown protection against driver overload. Supports data rates above 30 Mbps supporting high-speed communication.

Features robust ±4 kV ESD protection. Compact 8-pin SO package for efficient board layout. Wide operating temperature range from -40°C to 85°C. Complies with JEDEC JESD97 standard for semiconductor ICs. Maintains high impedance state at power off or during 3-state output.

This line transceiver from STMicroelectronics is suitable for industrial automation, data communication, instrumentation, and networking applications requiring reliable differential signaling and noise immunity.
