PIN FUNCTION DESCRIPTIONS

Mnemonic

Function

VCC

Power Supply Input +2.7 V to +3.6 V. Requires capacitor of 1

µF or greater to GND.

V+

Internally generated positive supply (+7.25 V nominal) Capacitor C4 is connected between VCC and V+.

V–

Internally generated negative supply (–7.25 V nominal) Capacitor C5 is connected between V– and GND.

GND

Ground Pin. Must be connected to 0 V.

C1+, C1–

External capacitor 1 is connected between these pins. A 0.1

µF capacitor is recommended, but larger capacitors

up to 1

µF may be used.

C2+, C2–

External capacitor 2 is connected between these pins. A 0.1

µF capacitor is recommended, but larger capacitors

up to 1

µF may be used.

C3+, C3–

External capacitor 3 is connected between these pins. A 0.1

µF capacitor is recommended, but larger capacitors

up to 1

µF may be used.

TIN

Transmitter (Driver) Inputs. These inputs accept TTL/CMOS levels. An internal 400 k

Ω pull-up resistor to V

CC

is connected on each input.

TOUT

Transmitter (Driver) Outputs, (typically

±6.4 V).

RIN

Receiver Inputs. These inputs accept RS-232 signal levels. An internal 5 k

Ω pull-down resistor to GND is

connected on each of these inputs.

ROUT

Receiver Outputs. These are TTL/CMOS levels.

EN

Receiver Enable. A high level three-states all the receiver outputs.

SD

Shutdown Control. A high level will disable the charge pump and reduce the quiescent current to 20 nA.

All transmitters and receivers R1–R4 are disabled. Receiver R5 remains active in shutdown.
