MAX3232EEUE+T

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

MAX3232EEUE+T from Analog Devices Inc Maxim Integrated, in a TSSOP-16. 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 charge-pump flying capacitor; requires 0.1μF capacitor for 3.3V operation (see Table 2 for other VCC values).
2 V+ power_out Internal doubling charge-pump positive output, nominally +5.5V over VCC = +3.0V to +5.5V; connect reservoir capacitor C3 (≥0.1μF at 3.3V) between this pin and GND.
3 C1- passive Negative terminal of the voltage-doubler charge-pump flying capacitor; requires 0.1μF capacitor for 3.3V operation (see Table 2 for other VCC values).
4 C2+ passive Positive terminal of the inverting charge-pump flying capacitor; requires 0.1μF capacitor for 3.3V operation (see Table 2 for other VCC values).
5 C2- passive Negative terminal of the inverting charge-pump flying capacitor; requires 0.1μF capacitor for 3.3V operation (see Table 2 for other VCC values).
6 V- power_out Internal inverting charge-pump negative output, nominally −5.5V over VCC = +3.0V to +5.5V; connect reservoir capacitor C4 (≥0.1μF at 3.3V) between this pin and GND.
7 T2OUT output RS-232 transmitter 2 output; ±5V minimum swing into 3kΩ ‖ 1000pF at ≤250kbps, short-circuit current ±60mA; ESD-protected to ±15kV HBM and ±8kV IEC 1000-4-2 contact discharge.
8 R2IN input RS-232 receiver 2 input; accepts ±25V input range, input resistance 3kΩ-7kΩ, input threshold low 0.6V-1.1V and high 1.5V-2.4V (VCC = 3.3V, TA = +25°C); ESD-protected to ±15kV HBM and ±8kV IEC 1000-4-2 contact discharge.
9 R2OUT output TTL/CMOS receiver 2 output; VOL ≤ 0.4V at IOUT = 1.6mA, VOH ≥ VCC − 0.6V at IOUT = −1.0mA; output leakage ±10μA max when disabled.
10 T2IN input TTL/CMOS transmitter 2 input; VIL ≤ 0.8V, VIH ≥ 2.0V (VCC = 3.3V), 0.5V hysteresis, input leakage ±1μA max; connect unused inputs to GND or VCC.
11 T1IN input TTL/CMOS transmitter 1 input; VIL ≤ 0.8V, VIH ≥ 2.0V (VCC = 3.3V), 0.5V hysteresis, input leakage ±1μA max; connect unused inputs to GND or VCC.
12 R1OUT output TTL/CMOS receiver 1 output; VOL ≤ 0.4V at IOUT = 1.6mA, VOH ≥ VCC − 0.6V at IOUT = −1.0mA; output leakage ±10μA max when disabled.
13 R1IN input RS-232 receiver 1 input; accepts ±25V input range, input resistance 3kΩ-7kΩ, input threshold low 0.6V-1.1V and high 1.5V-2.4V (VCC = 3.3V, TA = +25°C); ESD-protected to ±15kV HBM and ±8kV IEC 1000-4-2 contact discharge.
14 T1OUT output RS-232 transmitter 1 output; ±5V minimum swing into 3kΩ ‖ 1000pF at ≤250kbps, short-circuit current ±60mA; ESD-protected to ±15kV HBM and ±8kV IEC 1000-4-2 contact discharge.
15 GND power_in Ground reference for all internal circuitry and charge pumps.
16 VCC power_in +3.0V to +5.5V supply voltage; supply current 0.3mA typical / 1mA maximum with no load, continuous power dissipation 754.7mW (derate 9.4mW/°C above +70°C).
