Generated Positive Supply Voltage for RS-232 Driver (7V). Connect a 1F capacitor between
VDD and GND.
VEE

9
Generated Negative Supply Voltage for RS-232 Driver (–6.3V). Connect a 1F capacitor
between VEE and GND.
SW

Ground.
CAP

Charge Pump Capacitor for Generated Negative Supply Voltage. Connect a 220nF capacitor
between CAP and SW.
VL
10
12
Logic Supply (1.8V-5.5V) for the receiver outputs, driver inputs, and control inputs. This pin
should be bypassed to GND with a 220nF capacitor if it’s not tied to VCC.
TIN (T1IN, T2IN)

14, 13 Driver Input(s), referenced to VL.
TOUT (T1OUT, T2OUT)

3, 4
RS-232 Driver Output(s).
RIN (R1IN, R2IN)
1
1, 2
RS-232 Receiver Input(s). Includes internal 5kΩ termination resistor(s).
ROUT (R1OUT, R2OUT)
12
16, 15
16, 15 Receiver Output(s), referenced to VL. Output is short-circuit protected to GND/VCC/VL, and is
high impedance in Shutdown mode, allowing data line sharing.
PS

10
—
Power Supply control pin, referenced to VL. Enables the integrated DC-DC converter.
MODE
9
11
—
Mode control pin, referenced to VL. See Table 1 for functionality.
ON/OFF
—
11
Transceiver enable pin, referenced to VL. A logic low puts the device in Shutdown mode and
places both driver and receiver outputs in a high impedance state.
