XL232Z

XINLUDA · RS232 ICs · SOP-16

XL232Z from XINLUDA, in a SOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 C1+ passive Positive lead of the C1 flying capacitor for the +5V-to-+10V charge-pump voltage doubler. Connect a 1µF/16V capacitor between C1+ and C1-.
2 V+ power_out Positive charge-pump output (~+10V) for the storage capacitor only. Bypass to GND with a 1µF/16V capacitor (C3). Do not use to power external circuitry beyond mA-level loads.
3 C1- passive Negative lead of the C1 flying capacitor for the +5V-to-+10V charge-pump voltage doubler.
4 C2+ passive Positive lead of the C2 flying capacitor for the +10V-to-−10V charge-pump voltage inverter. Connect a 1µF/16V capacitor between C2+ and C2-.
5 C2- passive Negative lead of the C2 flying capacitor for the +10V-to-−10V charge-pump voltage inverter.
6 V- power_out Negative charge-pump output (~−10V) for the storage capacitor only. Bypass to GND with a 1µF/16V capacitor (C4). Not regulated; do not load beyond mA-level.
7 T2OUT output RS-232 line data output of driver 2, sent to the remote RS-232 system. Typical swing ±8V into a 5kΩ receiver, guaranteed ±5V minimum into 3kΩ at VCC=+4.5V.
8 R2IN input RS-232 line data input of receiver 2, driven by the remote RS-232 system. Withstands ±25V input; internal 5kΩ (typ) input termination resistor to GND.
9 R2OUT output TTL/CMOS logic data output of receiver 2, driven to the local UART. VOH ≥ 3.5V at IOUT=−1mA; VOL ≤ 0.4V at IOUT=1.6mA.
10 T2IN input TTL/CMOS logic data input of driver 2 from the local UART. Internal 400kΩ pull-up to VCC; may be left unconnected on unused drivers.
11 T1IN input TTL/CMOS logic data input of driver 1 from the local UART. Internal 400kΩ pull-up to VCC; may be left unconnected on unused drivers.
12 R1OUT output TTL/CMOS logic data output of receiver 1, driven to the local UART. VOH ≥ 3.5V at IOUT=−1mA; VOL ≤ 0.4V at IOUT=1.6mA.
13 R1IN input RS-232 line data input of receiver 1, driven by the remote RS-232 system. Withstands ±25V input; internal 5kΩ (typ) input termination resistor to GND.
14 T1OUT output RS-232 line data output of driver 1, sent to the remote RS-232 system. Typical swing ±8V into a 5kΩ receiver, guaranteed ±5V minimum into 3kΩ at VCC=+4.5V.
15 GND power_in Device ground / 0V reference.
16 VCC power_in Supply voltage input; connect to external +5V (+5V ±5% operating; absolute maximum +6V). Decouple to GND with a capacitor equal to C1/C2 (1µF) placed as close to the device as possible.
