UM3090
Description
The UM3090EESA is ±15kV ESD-protected, high-speed transceiver for RS-485 munication that contains one internal low-dropout regulator, one driver and one receiver.
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
