ADM202JNZ from Analog Devices, in a PDIP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | C1+ | passive | External positive terminal connection for charge pump capacitor C1 used to double VCC to the internal V+ supply. |
| 2 | V+ | power_out | Internally generated positive supply of +10 V nominal, which may power external circuitry only for small current requirements. |
| 3 | C1− | passive | External negative terminal connection for charge pump capacitor C1. |
| 4 | C2+ | passive | External positive terminal connection for charge pump capacitor C2 used in the voltage inverter. |
| 5 | C2− | passive | External negative terminal connection for charge pump capacitor C2 used in the voltage inverter. |
| 6 | V− | power_out | Internally generated negative supply of −10 V nominal, which may power external circuitry only for small current requirements. |
| 7 | T2OUT | output | RS-232 transmitter 2 output at RS-232 levels, typically ±10 V. |
| 8 | R2IN | input | RS-232 receiver 2 input accepting RS-232 signal levels, with an internal 5 kΩ pull-down resistor to GND and overvoltage protection up to ±30 V. |
| 9 | R2OUT | output | RS-232 receiver 2 output at TTL/CMOS levels. |
| 10 | T2IN | input | TTL/CMOS transmitter 2 input with an internal 400 kΩ pull-up resistor to VCC, so an unused input pulls the output low. |
| 11 | T1IN | input | TTL/CMOS transmitter 1 input with an internal 400 kΩ pull-up resistor to VCC, so an unused input pulls the output low. |
| 12 | R1OUT | output | RS-232 receiver 1 output at TTL/CMOS levels. |
| 13 | R1IN | input | RS-232 receiver 1 input accepting RS-232 signal levels, with an internal 5 kΩ pull-down resistor to GND and overvoltage protection up to ±30 V. |
| 14 | T1OUT | output | RS-232 transmitter 1 output at RS-232 levels, typically ±10 V. |
| 15 | GND | power_in | Ground pin that must be connected to 0 V. |
| 16 | VCC | power_in | Power supply input of 5 V ± 10%. |
