MAX202CSE+T

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

MAX202CSE+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 the 0.1µF flying capacitor C1 that the voltage doubler uses to generate V+ from VCC.
2 V+ power_out Doubler output that stores approximately +10V on the V+ output filter capacitor (C3) and supplies the RS-232 driver positive swing.
3 C1- passive Negative terminal of the 0.1µF flying capacitor C1 used by the voltage doubler.
4 C2+ passive Positive terminal of the 0.1µF flying capacitor C2 used by the voltage inverter that generates V- from V+.
5 C2- passive Negative terminal of the 0.1µF flying capacitor C2 used by the voltage inverter.
6 V- power_out Inverter output that stores approximately -10V on the V- output filter capacitor (C4) and supplies the RS-232 driver negative swing.
7 T2OUT output RS-232 driver 2 output that gives at least ±5V into a 3kΩ load under worst-case conditions (typical ±8V with a 5kΩ receiver and VCC = +5V).
8 R2IN input RS-232 receiver 2 input rated for ±30V, with +0.8V/+2.4V thresholds, about 0.5V hysteresis, and about 5kΩ input resistance to ground.
9 R2OUT output TTL/CMOS receiver 2 output (inverting), specified at 0.4V maximum low at 3.2mA and 3.5V minimum high at 1.0mA.
10 T2IN input TTL/CMOS driver 2 input with 0.8V maximum low and 2.0V minimum high thresholds and an internal 400kΩ pullup to VCC, so an open input drives the output low.
11 T1IN input TTL/CMOS driver 1 input with 0.8V maximum low and 2.0V minimum high thresholds and an internal 400kΩ pullup to VCC, so an open input drives the output low.
12 R1OUT output TTL/CMOS receiver 1 output (inverting), specified at 0.4V maximum low at 3.2mA and 3.5V minimum high at 1.0mA.
13 R1IN input RS-232 receiver 1 input rated for ±30V, with +0.8V/+2.4V thresholds, about 0.5V hysteresis, and about 5kΩ input resistance to ground.
14 T1OUT output RS-232 driver 1 output that gives at least ±5V into a 3kΩ load under worst-case conditions (typical ±8V with a 5kΩ receiver and VCC = +5V).
15 GND power_in Ground reference for the device, the charge pump, and the RS-232 signals.
16 VCC power_in Single +5V supply input (VCC = +5V ±10% for MAX202), drawing a typical 8mA and a maximum 15mA with no load.
