MAX232CSE+T

Analog Devices Inc Maxim Integrated · RS232 ICs · SOIC-16

MAX232CSE+T from Analog Devices Inc Maxim Integrated, 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, which is 1.0µF for the MAX232 in the datasheet capacitor table.
2 V+ power_out Doubler charge-pump output at nominally +10V unloaded; it is not regulated and must not be loaded so far that the RS-232 driver output falls below the ±5V EIA/TIA-232E minimum.
3 C1- passive Negative terminal of charge-pump capacitor C1, which is 1.0µF for the MAX232 in the datasheet capacitor table.
4 C2+ passive Positive terminal of charge-pump capacitor C2, which is 1.0µF for the MAX232 in the datasheet capacitor table.
5 C2- passive Negative terminal of charge-pump capacitor C2, which is 1.0µF for the MAX232 in the datasheet capacitor table.
6 V- power_out Inverter charge-pump output at nominally -10V unloaded; it is not regulated and must not be loaded so far that the RS-232 driver output falls below the ±5V EIA/TIA-232E minimum.
7 T2OUT output RS-232 driver 2 output, typically ±8V with a 5kΩ load and VCC = +5V, guaranteed to ±5V minimum with a 3kΩ load, and can be driven to ±15V.
8 R2IN input RS-232 receiver 2 input with an internal nominal 5kΩ terminating resistor, withstanding input voltages up to ±30V on devices other than the MAX220.
9 R2OUT output TTL/CMOS receiver 2 output; the receiver inverts, and the output is limited to -0.3V to (VCC + 0.3V).
10 T2IN input TTL/CMOS-compatible driver 2 input with a built-in 400kΩ pullup to VCC; leave unused driver inputs unconnected or tie them high, since the pullup forces the unused driver output low.
11 T1IN input TTL/CMOS-compatible driver 1 input with a built-in 400kΩ pullup to VCC; leave unused driver inputs unconnected or tie them high, since the pullup forces the unused driver output low.
12 R1OUT output TTL/CMOS receiver 1 output; the receiver inverts, and the output is limited to -0.3V to (VCC + 0.3V).
13 R1IN input RS-232 receiver 1 input with an internal nominal 5kΩ terminating resistor, withstanding input voltages up to ±30V on devices other than the MAX220.
14 T1OUT output RS-232 driver 1 output, typically ±8V with a 5kΩ load and VCC = +5V, guaranteed to ±5V minimum with a 3kΩ load, and can be driven to ±15V.
15 GND power_in Ground reference (0V) for all device voltages.
16 VCC power_in Supply input at +5V ±10% per the electrical characteristics, with absolute maximum rating of -0.3V to +6V.
