PIN OUT FUNCTION TABLES BY
MODEL NUMBER
The following tables detail pin out functions by the DDC model
number.
The RDC-19220S has differential inputs but requires both ±5 V
power supplies.
The RDC-19222S has differential inputs and can be used with
±5 V or +5 V only.

DESCRIPTION
TABLE 8. RDC-19222S (44-PIN) PIN OUTS
TABLE 7. RDC-19220S (40 PIN) PIN OUTS
Note: When using the built-in -5 V inverter: connect pin 2 to 26, pin 17 to 22, and
a 10 F/10 VDC capacitor from pin 23 (negative terminal) to pin 25 (posi-
tive terminal). Connect a 47 F/10 VDC capacitor from -5 V to GND. The
current drain from the +5 V supply doubles. No external -5 V supply is
needed.
