MAX3232EEAE+T

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

MAX3232EEAE+T from Analog Devices Inc Maxim Integrated, in a SSOP-16-208mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 C1+ passive Positive terminal of the voltage-doubler flying capacitor; connect a 0.1µF capacitor between C1+ and C1− for +3.3V operation (see Table 2 for other supply voltages).
2 V+ power_out Internal charge-pump positive supply output, nominally +5.5V; connect 0.1µF reservoir capacitor C3 from V+ to GND.
3 C1- passive Negative terminal of the voltage-doubler flying capacitor; connect a 0.1µF capacitor between C1+ and C1−.
4 C2+ passive Positive terminal of the inverting charge-pump flying capacitor; connect a 0.1µF capacitor between C2+ and C2−.
5 C2- passive Negative terminal of the inverting charge-pump flying capacitor; connect a 0.1µF capacitor between C2+ and C2−.
6 V- power_out Internal charge-pump negative supply output, nominally −5.5V; connect 0.1µF reservoir capacitor C4 from V− to GND.
7 T2OUT output RS-232 transmitter output 2 (inverting); ±5V minimum swing into 3kΩ load (typ ±5.4V), 250kbps guaranteed, ±15kV ESD-protected (HBM), short-circuit current ±60mA continuous.
8 R2IN input RS-232 receiver input 2; accepts ±25V input range, 3kΩ-7kΩ input resistance, input threshold low 0.6-1.5V / high 1.5-2.4V (VCC = +3.3V), ±15kV ESD-protected (HBM, IEC 1000-4-2).
9 R2OUT output TTL/CMOS receiver output 2 (inverting); VOL ≤ 0.4V at IOUT = 1.6mA, VOH ≥ VCC−0.6V at IOUT = −1.0mA.
10 T2IN input TTL/CMOS transmitter input 2; VIL ≤ 0.8V, VIH ≥ 2.0V at VCC = +3.3V (2.4V at +5V), 0.5V hysteresis; connect to GND or VCC if unused.
11 T1IN input TTL/CMOS transmitter input 1; VIL ≤ 0.8V, VIH ≥ 2.0V at VCC = +3.3V (2.4V at +5V), 0.5V hysteresis; connect to GND or VCC if unused.
12 R1OUT output TTL/CMOS receiver output 1 (inverting); VOL ≤ 0.4V at IOUT = 1.6mA, VOH ≥ VCC−0.6V at IOUT = −1.0mA.
13 R1IN input RS-232 receiver input 1; accepts ±25V input range, 3kΩ-7kΩ input resistance, 0.5V input hysteresis, ±15kV ESD-protected (HBM, IEC 1000-4-2).
14 T1OUT output RS-232 transmitter output 1 (inverting); ±5V minimum swing into 3kΩ load (typ ±5.4V), 250kbps guaranteed, ±15kV ESD-protected (HBM), output resistance ≥300Ω when VCC = 0V.
15 GND power_in Ground (0V) reference for all internal circuitry and charge-pump returns.
16 VCC power_in +3.0V to +5.5V supply voltage; typical quiescent current 1mA (max), bypass with 0.1µF capacitor placed close to the IC.
