(Pins 1, 9):
Driver Supply Pins. Supply current
drops to zero in shutdown mode. Driver outputs are in a
high impedance state when V
+
and V
–
= 0V.
BIAS (Pin 2):
Keeps receiver 1 on while the LT1309A is in
the shutdown mode. Leave BIAS pin open when not in use.
See Applications Information for proper use.
REC IN (Pins 3, 5, 7):
Receiver Input Pins. Accepts RS232
voltage levels (
±
30V) and has 0.4V of hysteresis to pro-
vide noise immunity. Input impedance is nominally 30k
.
Receiver input pins are internally protected from ESD
transients. In order to insure proper functioning of the ESD
protection devices, the V
CC
and V
–
supply pins must be
bypassed with low ESR capacitors located close to the
pins. A 0.1
μ
F ceramic capacitor works well.
TR OUT (Pins 4, 6, 8):
Driver Outputs with RS232 Voltage
Levels. Outputs are in a high impedance state when in the
shutdown mode or when power is off (V
+
and V
–
= 0V) to
allow data line sharing. Outputs are fully short-circuit
protected from V
–
+ 30V to V
+
– 30V with power on, off or
in the shutdown mode. Typical output breakdowns are
greater than
±
45V and higher applied voltages will not
damage the device if moderately current limited. Driver
(Pin numbers listed are for 18-pin device)
output pins are internally protected from ESD transients.
In order to insure proper functioning of the ESD protec-
tion devices, the V
+
and V
–
supply pins must be
bypassed with low ESR capacitors located close to the
pins. 0.1
μ
F ceramic capacitors work well.
GND (Pin 10):
Ground Pin.
TR IN (Pins 11, 13, 15):
RS232 Driver Input Pins. Inputs
are TTL/CMOS compatible. Inputs should not be allowed
to float. Tie unused inputs to V
CC
.
REC OUT (Pins 12, 14, 16):
Receiver Outputs with TTL/
CMOS Voltage Levels. Outputs are in a high impedance
state when in the shutdown mode to allow data line
sharing. Outputs are fully short-circuit protected to ground
or V
CC
with power on, off or in the shutdown mode.
ON/OFF (Pin 17):
Controls the operation mode of the
LT1039A and is TTL/CMOS compatible. A logic low puts
the device in the shutdown mode which reduces input
supply current to zero and places both driver and receiver
outputs in a high impedance state.
