UM488 Slew-Rate-Limited RS-422 Transceivers

UM488 Description

UM488/UM491 ±15kV ESD-Protected, Fail-Safe, Slew-Rate-Limited RS-422 Transceivers in SOP8/DIP8/SOP14/DIP14 General .
The UM488/UM491 is ±15kV electrostatic discharge (ESD)-protected, high-speed transceivers for RS-422 communication that contain one driver and one re.

UM488 Features

* fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted. This means that the receiver output will be a logic high if all transmitters on a terminated bus are disabled (high impedance). The UM488/UM491 offers higher driver output slew-rate limit
