SP232ECN-L

MaxLinear · Pre-ordered Chips · SOIC-16

SP232ECN-L from MaxLinear, 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 charge pump capacitor C1, a 0.1µF to 10µF capacitor.
2 V+ power_out Positive charge pump output (about +6V for driver swing), decoupled with a storage capacitor; absolute maximum 11.0V.
3 C1- passive Negative terminal of charge pump capacitor C1.
4 C2+ passive Positive terminal of charge pump capacitor C2.
5 C2- passive Negative terminal of charge pump capacitor C2.
6 V- power_out Negative charge pump output (about -6V for driver swing), decoupled with a storage capacitor; absolute maximum -11.0V.
7 T2OUT output RS-232 transmitter 2 output with typical ±6V swing, ±5.0V minimum into 3kΩ, short-circuit protected, ±15kV HBM ESD.
8 R2IN input RS-232 receiver 2 input with voltage range ±15V, internal 5kΩ pull-down, ±15kV HBM ESD.
9 R2OUT output TTL/CMOS receiver 2 output, inverted relative to R2IN, low 0.4V max at 3.2mA.
10 T2IN input TTL/CMOS transmitter 2 input with logic thresholds 0.8V low and 2.0V high and internal pull-up.
11 T1IN input TTL/CMOS transmitter 1 input with logic thresholds 0.8V low and 2.0V high and internal pull-up.
12 R1OUT output TTL/CMOS receiver 1 output, inverted relative to R1IN, low 0.4V max at 3.2mA.
13 R1IN input RS-232 receiver 1 input with voltage range ±15V, internal 5kΩ pull-down, ±15kV HBM ESD.
14 T1OUT output RS-232 transmitter 1 output with typical ±6V swing, ±5.0V minimum into 3kΩ, short-circuit protected, ±15kV HBM ESD.
15 GND power_in Ground.
16 VCC power_in Single +5V ±10% supply input; absolute maximum 6.0V.
