provides for the removal of the
transmitter output from the line. A
logic “1” applied to the “INHIBIT”
takes priority over the condition of
the data inputs and disables the
transmitter. (See Transmitter Logic
Waveform, Figure 1.)
The transceiver utilizes an active
filter to suppress harmonics above

1.150 Volts P-P and reject signals
less than 0.6 volts P-P when used
with a 1:1 turns ratio transformer.

and typical connection.)
