SP232ECN-TD

TDSEMIC · RS232 ICs · SOP-16

SP232ECN-TD from TDSEMIC, in a SOP-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 Terminal for the positive side of the charge-pump C1 capacitor (1.0µF).
2 V+ power_out Positive voltage generated by the charge-pump; absolute maximum 9.8V, with a 1.0µF capacitor in the application circuit.
3 C1- passive Terminal for the negative side of the charge-pump C1 capacitor (1.0µF).
4 C2+ passive Terminal for the positive side of the charge-pump C2 capacitor (1.0µF).
5 C2- passive Terminal for the negative side of the charge-pump C2 capacitor (1.0µF).
6 V- power_out Negative voltage generated by the charge-pump; absolute maximum -9.0V, with a 1.0µF capacitor to ground in the application circuit.
7 T2OUT output RS-232 driver 2 output (RS-232 levels).
8 R2IN input RS-232 receiver 2 input (RS-232 levels, ±20V input range) with an internal 5K pulldown.
9 R2OUT output RS-232 receiver 2 output (TTL/CMOS levels).
10 T2IN input RS-232 driver 2 input (TTL/CMOS levels).
11 T1IN input RS-232 driver 1 input (TTL/CMOS levels).
12 R1OUT output RS-232 receiver 1 output (TTL/CMOS levels).
13 R1IN input RS-232 receiver 1 input (RS-232 levels, ±20V input range) with an internal 5K pulldown.
14 T1OUT output RS-232 driver 1 output (RS-232 levels).
15 GND power_in Ground.
16 VCC power_in Supply voltage input, 4.5V to 5.5V recommended, 6.0V absolute maximum.
