PIN DESCRIPTIONS

VSS

Most Negative Device Pin

VCC

Digital Power Supply

The most negative power supply pin, which is typically – 5 to – 12V.

The digital supply pin, which is connected to the logic power Rx1 – Rxn

supply (+ 5.5 V maximum).

Receive Data Input Pins

GND

These are the EIA–232–E receive signal inputs. A voltage

between + 3 and + 25 V is decoded as a space, and causes the

corresponding DO pin to swing to ground (0 V). A voltage

between – 3 and – 25 V is decoded as a mark, and causes the

Ground

Ground return pin is typically connected to the signal ground

pin of the EIA–232–E connector (Pin 7) as well as to the logic

power supply ground.

Data Output Pins

VDD

Most Positive Device Pin

These are the receiver digital output pins which swing

fromV to GND. Each output pin is capable of driving one

The most positive power supply pin, which is typically + 5 to
