MAX3232ECAE+T

Analog Devices Inc Maxim Integrated · RS232 ICs · SSOP-16-208mil

MAX3232ECAE+T from Analog Devices Inc Maxim Integrated, in a SSOP-16-208mil. 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 doubler charge-pump capacitor C1, which uses 0.1µF at a 3.3V supply.
2 V+ power_out Doubler charge-pump output that generates +5.5V across the full +3.0V to +5.5V VCC range.
3 C1- passive Negative terminal of the doubler charge-pump capacitor C1.
4 C2+ passive Positive terminal of the inverting charge-pump capacitor C2.
5 C2- passive Negative terminal of the inverting charge-pump capacitor C2.
6 V- power_out Inverting charge-pump output that generates −5.5V across the full +3.0V to +5.5V VCC range.
7 T2OUT output RS-232 transmitter output that guarantees at least ±5V swing with a 3kΩ load to ground, with ±60mA typical short-circuit current.
8 R2IN input RS-232 receiver input with an input voltage range of −25V to +25V and typical input resistance of 5kΩ.
9 R2OUT output TTL/CMOS receiver output, inverting relative to R2IN, that holds VCC − 0.6V minimum high at −1.0mA.
10 T2IN input TTL/CMOS transmitter input with no pull-up, so unused inputs must be tied to GND or VCC.
11 T1IN input TTL/CMOS transmitter input with no pull-up, so unused inputs must be tied to GND or VCC.
12 R1OUT output TTL/CMOS receiver output, inverting relative to R1IN, that holds VCC − 0.6V minimum high at −1.0mA.
13 R1IN input RS-232 receiver input with an input voltage range of −25V to +25V and typical input resistance of 5kΩ.
14 T1OUT output RS-232 transmitter output that guarantees at least ±5V swing with a 3kΩ load to ground, with ±60mA typical short-circuit current.
15 GND power_in Ground reference for the device.
16 VCC power_in Supply input, +3.0V to +5.5V.
