ADM202EARNZ-REEL

Analog Devices · RS232 ICs · SOIC-16

ADM202EARNZ-REEL from Analog Devices, in a SOIC-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 Positive terminal of external charge-pump capacitor C1; a 0.1 µF capacitor is recommended, and values up to 47 µF can be used.
2 V+ power_out Internally generated positive supply, +9 V nominal, which needs the external reservoir capacitor C3 to be connected as shown in the datasheet.
3 C1− passive Negative terminal of external charge-pump capacitor C1; a 0.1 µF capacitor is recommended, and values up to 47 µF can be used.
4 C2+ passive Positive terminal of external charge-pump capacitor C2; a 0.1 µF capacitor is recommended, and values up to 47 µF can be used.
5 C2− passive Negative terminal of external charge-pump capacitor C2; a 0.1 µF capacitor is recommended, and values up to 47 µF can be used.
6 V− power_out Internally generated negative supply, −9 V nominal.
7 T2OUT output RS-232 transmitter 2 output at RS-232 signal levels, typically ±9 V.
8 R2IN input RS-232 receiver 2 input that accepts RS-232 levels, with an internal 5 kΩ pull-down to GND and protection to ±30 V.
9 R2OUT output Receiver 2 CMOS logic-level output.
10 T2IN input Transmitter 2 input that accepts TTL/CMOS logic levels (VIL max 0.8 V, VIH min 2.4 V).
11 T1IN input Transmitter 1 input that accepts TTL/CMOS logic levels (VIL max 0.8 V, VIH min 2.4 V).
12 R1OUT output Receiver 1 CMOS logic-level output.
13 R1IN input RS-232 receiver 1 input that accepts RS-232 levels, with an internal 5 kΩ pull-down to GND and protection to ±30 V.
14 T1OUT output RS-232 transmitter 1 output at RS-232 signal levels, typically ±9 V.
15 GND power_in Ground pin, which must be connected to 0 V.
16 VCC power_in Power supply input, 5 V ±10% (4.5 V to 5.5 V).
