FIGURE 17. TYPICAL -5 VOLT CIRCUITS
TYPICAL-5 VOLT CIRCUITS
Since the 40-pin DDIP RDC-19220 does not have a pinout for
the -5 V inverter, it may be necessary to create a -5 V from other
supplies on the board. FIGURE 17 illustrates several possibili-
ties.

NOTES:
1. When -5 V is applied to pin 1 (EL), Converter Busy (CB) becomes
Zero index (ZI).
2. 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 (positive terminal). Connect a 47 F/10 Vdc capacitor from -5
V to GND. The current drain from the +5 V supply doubles. No exter-
nal -5 V supply is needed.
TABLE 9. RDC-19222 PINOUTS (44-PIN, +5 V ONLY)
PINOUT FUNCTION TABLES BY MODEL NUMBER
The TABLES 8 and 9 detail pinout functions by the DDC model
number.
The RDC-19220 has differential inputs but requires both ±5 V
power supplies.
The RDC-19222 has differential inputs and can be used with the
+5 V only option.
