3V Low Power，±15kV ESD-Protected, Fail-Safe, RS-422 Transceivers UM3488EESA SOP8 UM3488EEPA DIP8 UM3491EESE SOP14 UM3491EEPE DIP14 General Description The UM3488/UM3491 is ±15kV electrostatic discharge (ESD)-protected, high-speed transceivers for RS-422 communication that contain one driver and one receiver.
The UM3491 contains an additional receiver and driver enable control.
The device 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 UM3488/UM3491 allows transmit speed...
