Pin Descriptions

MODE

FUNCTION

GND

BOTH

Ground connection.

LB

BOTH

Enables loopback mode when low. Internally pulled-high.

NC

BOTH

No Connection.

ON/OFF

BOTH

If either port is in RS-232 mode, a low on ON/OFF disables the charge pumps. In either mode, a low disables all the outputs,

and places the device in low power shutdown. Internally pulled-high. ON = 1 for normal operation.

RXEN1

RXEN2

BOTH

Active low receiver output enable. Rx is enabled when RXEN is low; Rx is high impedance when RXEN is high. Internally

pulled low. (QFN only)

SEL

BOTH

Interface Mode Select input. High puts corresponding port in RS-485 Mode, while a low puts it in RS-232 Mode.

VCC

BOTH

System power supply input (5V).

VL

BOTH

Logic-Level Supply. All TTL/CMOS inputs and outputs are powered by this supply. QFN logic input pins that are externally

tied high in the application should use the VL supply for the high voltage level. (QFN only)

A

RS-232 Receiver input with ±15kV ESD protection. A low on A forces RA high; a high on A forces RA low.

RS-485 Inverting receiver input with ±15kV ESD protection.

B

RS-232 Receiver input with ±15kV ESD protection. A low on B forces RB high; a high on B forces RB low.

RS-485 Noninverting receiver input with ±15kV ESD protection.

DY

RS-232 Driver input. A low on DY forces output Y high. Similarly, a high on DY forces output Y low.

RS-485 Driver input. A low on DY forces output Y high and output Z low. Similarly, a high on DY forces output Y low and output Z high.

DZ

RS-232 Driver input. A low on DZ forces output Z high. Similarly, a high on DZ forces output Z low.

DE

RS-485 Driver output enable. The driver outputs, Y and Z, are enabled by bringing DE high. They are high impedance when DE is

low. Internally pulled high when port selected for RS-485 mode.

RA

RS-232 Receiver output.

RS-485 Receiver output: If B > A by at least -40mV, RA is high; If B < A by -200mV or more, RA is low; RA = High if A and B are

unconnected (floating) or shorted together (i.e., full fail-safe).

RB

RS-232 Receiver output.

RS-485 Not used. Internally pulled-high, and unaffected by RXEN.

Y

RS-232 Driver output with ±15kV ESD protection.

RS-485 Inverting driver output with ±15kV ESD protection.

Z

RS-232 Driver output with ±15kV ESD protection.

RS-485 Noninverting driver output with ±15kV ESD protection.

SP

RS-485 Speed control. Internally pulled-high. (QFN only)

C1+

RS-232 External capacitor (voltage doubler) is connected to this lead. Not needed if both ports in RS-485 Mode.

C1-

RS-232 External capacitor (voltage doubler) is connected to this lead. Not needed if both ports in RS-485 Mode.

C2+

RS-232 External capacitor (voltage inverter) is connected to this lead. Not needed if both ports in RS-485 Mode.

C2-

RS-232 External capacitor (voltage inverter) is connected to this lead. Not needed if both ports in RS-485 Mode.

V+

RS-232 Internally generated positive RS-232 transmitter supply (+5.5V). C3 not needed if both ports in RS-485 Mode.

V-

RS-232 Internally generated negative RS-232 transmitter supply (-5.5V). C4 not needed if both ports in RS-485 Mode.
