ST202EBDR

STMicroelectronics · RS232 ICs · SO-16

ST202EBDR from STMicroelectronics, in a SO-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 for first charge pump capacitor.
2 V+ power_out Doubled voltage terminal from internal charge pump.
3 C1- passive Negative terminal for first charge pump capacitor.
4 C2+ passive Positive terminal for second charge pump capacitor.
5 C2- passive Negative terminal for second charge pump capacitor.
6 V- power_out Inverted voltage terminal from internal charge pump.
7 T2OUT output Second transmitter RS-232 output; ±5 to ±9 V swing with 3 kΩ load to GND.
8 R2IN input Second receiver RS-232 input; ±30 V operating range.
9 R2OUT output Second receiver TTL/CMOS output; 0.4 V low, 3.5 to VCC-0.4 V high.
10 T2IN input Second transmitter TTL/CMOS input; 0.8 V low and 2 V high logic thresholds.
11 T1IN input First transmitter TTL/CMOS input; 0.8 V low and 2 V high logic thresholds.
12 R1OUT output First receiver TTL/CMOS output; 0.4 V low, 3.5 to VCC-0.4 V high.
13 R1IN input First receiver RS-232 input; ±30 V operating range.
14 T1OUT output First transmitter RS-232 output; ±5 to ±9 V swing with 3 kΩ load to GND.
15 GND power_in Ground reference potential.
16 VCC power_in Positive supply voltage; 5 V ± 10%, absolute maximum -0.3 to 6 V.
