DRIVER IN:
RS232 Driver Input Pins. Inputs are TTL/
CMOS compatible. Inputs should not be allowed to float.
Tie unused inputs to V
CC
.
DRIVER OUT:
Driver Outputs at RS232 Voltage Levels.
Outputs are in a high impedance state when in SHUT-
DOWN mode or V
CC
= 0V. The driver outputs are protected
against ESD to
±
10kV for human body model discharges.
U
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 Lev-
els. Receiver 1, 2 and 3 outputs are in a high impedance
state when in SHUTDOWN mode to allow data line sharing.
Receivers 4 and 5 are kept alive in SHUTDOWN.
