ST485BN Description

Short technical summary and product information.

The ST485BN from ST is a low power transceiver suitable for RS-485 and RS-422 communication interfaces. This device integrates one driver and one receiver, operating from a single 5V supply.

 

Key electrical characteristics include a low quiescent current of 300μA (typical) when unloaded or fully loaded with disabled drivers. It offers propagation delays of 30ns and a typical input hysteresis of 70mV. The common-mode input voltage range is -7V to 12V.

 

The ST485BN is designed for bi-directional data communications on multipoint bus transmission lines, supporting half-duplex applications. It allows up to 64 transceivers on the bus. The driver includes current limiting and thermal shutdown protection for overload conditions.

 

This transceiver is available in a DIP-8 package, making it suitable for through-hole mounting. The operating temperature range is -40°C to 85°C.
