Transmitter 1 Input
Noninverting Transmitter 1 Output
Inverting Transmitter 1 Output
Transmitter Enable High Input. Drive EN high to enable all four
transmitters. When EN is low and EN is high, all transmitters are
disabled and the part enters a low-power shutdown state. The
transmitter outputs are high impedance when disabled.
Transmitter Enable Input to Control Transmitters 1 and 2. Drive EN12
high to enable transmitters 1 and 2. Drive EN12 low to disable
transmitters 1 and 2. The transmitter outputs are high impedance
when disabled. The part enters a low-power shutdown state when
both EN12 and EN34 are low.

disabled and the part enters a low-power shutdown state. The
transmitter outputs are high impedance when disabled.
Transmitter Enable Input to Control Transmitters 3 and 4. Drive EN34
high to enable transmitters 3 and 4. Drive EN34 low to disable
transmitters 3 and 4. The transmitter outputs are high impedance
when disabled. The part enters a low-power shutdown state when
both EN12 and EN34 are low.
