General Description

The UM3090EESA is ±15kV ESD-protected, high-speed transceiver for RS-485 communication that contains one internal low-dropout regulator, one driver and one receiver.

The internal LDO allows the device to operate from an unregulated power supply of up to 30V.

The internal LDO generates a 5V±5% power supply that is used to power its internal circuitry.

Overview

UM3090 ±15kV ESD-Protected, Slew-Rate-Limited, Fail-Safe, True RS-485 Transceivers with Integrated Low-Dropout Regulator UM3090EESA SOP8-EP.

Key Features

fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open, shorted or idle. This means that the receiver output will be logic high if all transmitters on a terminated bus are disabled (high impedance). The UM3090EESA features reduced slew-rate driver that.
