Transmitter Inputs. When the corresponding transmitter is enabled, a low on DI_ forces
the noninverting output low and inverting output high. Similarly, a high on DI_ forces
noninverting output high and inverting output low.

EN
Transmitter Enable Input: Active HIGH. Drive EN HIGH to enable all transmitters. When
EN is HIGH, drive EN LOW to disable (three-state) all the transmitters. The transmitter
outputs are high impedance when disabled. EN is hot-swap protected (see the Hot
Swap section).

GND
Ground

EN
Transmitter Enable Input: Active LOW. Drive EN LOW to enable all transmitters. When
EN is LOW, drive EN HIGH to disable all the transmitters. The transmitter outputs are
high impedance when disabled. EN is hot-swap protected (see the Hot Swap section).
4
EN1&2
Transmitter Enable Input for Channels 1 and 2. Drive EN1&2 HIGH to enable the
corresponding transmitters. Drive EN1&2 LOW to disable the corresponding
transmitters. The transmitter outputs are high impedance when disabled. EN1&2 is hot-
swap protected (see the Hot Swap section).
12
EN3&4
Transmitter Enable Input for Channels 3 and 4. Drive EN3&4 HIGH to enable the
corresponding transmitters. Drive EN3&4 LOW to disable the corresponding
transmitters. The transmitter outputs are high impedance when disabled. EN3&4 is hot-
swap protected (see the Hot Swap section).
