TR IN: EIA/TIA562 Driver Input Pins. Inputs are TTL/
CMOS compatible. The inputs of unused drivers can be left
unconnected since 300k input pull-up resistors to V
included on chip.
TR OUT: Driver Outputs at EIA/TIA562 Voltage Levels.
The driver outputs are protected against ESD to ±10kV for
human body model discharges.
RX IN: Receiver Inputs. These pins can be forced to ±25V
without damage. The receiver inputs are protected against
ESD to ±10kV for human body model discharges. Each
receiver provides 0.4V of hysteresis for noise immunity.
RX OUT: Receiver Outputs with TTL/CMOS Voltage
Levels.
