MAX232ESE+T

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

MAX232ESE+T from Analog Devices Inc Maxim Integrated, in a SOIC-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 +5V-to-+10V voltage-doubler flying capacitor C1. Connect C1 (1.0µF for MAX232, 0.1µF for MAX232A) between C1+ and C1-.
2 V+ power_out Regulated +10V output from the internal charge-pump voltage doubler. Bypass to GND with a 1.0µF capacitor (0.1µF for MAX232A). Only small external loads (a few mA) may be drawn.
3 C1- passive Negative terminal of the +5V-to-+10V voltage-doubler flying capacitor C1.
4 C2+ passive Positive terminal of the +10V-to-−10V inverting flying capacitor C2 (1.0µF for MAX232, 0.1µF for MAX232A).
5 C2- passive Negative terminal of the +10V-to-−10V inverting flying capacitor C2.
6 V- power_out Regulated −10V output from the internal charge-pump voltage inverter. Bypass to GND with a 1.0µF capacitor (0.1µF for MAX232A).
7 T2OUT output RS-232 driver #2 output. Swings nominally ±8V into a 5kΩ load, guaranteed ≥±5V per EIA/TIA-232E; slew rate limited to <30V/µs; short-circuit current typically ±10mA.
8 R2IN input RS-232 receiver #2 input. Accepts ±30V input, ~5kΩ input resistance, thresholds ~0.8V (low) / ~2.4V (high) with ~0.5V typical hysteresis. Withstands overvoltage to ±25V.
9 R2OUT output TTL/CMOS receiver #2 output. Inverted logic level from R2IN. VOL ≤0.4V at IOUT=3.2mA; VOH ≥3.5V at IOUT=−1.0mA.
10 T2IN input TTL/CMOS driver #2 input. Internal ~400kΩ pull-up to VCC forces unused-driver output low. Logic thresholds 0.8V (low) / 2.0V (high).
11 T1IN input TTL/CMOS driver #1 input. Internal ~400kΩ pull-up to VCC. Logic thresholds 0.8V (low) / 2.0V (high).
12 R1OUT output TTL/CMOS receiver #1 output. Inverted logic level from R1IN.
13 R1IN input RS-232 receiver #1 input. Accepts ±30V input, ~5kΩ input resistance, thresholds ~0.8V (low) / ~2.4V (high) with hysteresis.
14 T1OUT output RS-232 driver #1 output. Swings nominally ±8V into a 5kΩ load; slew rate <30V/µs.
15 GND power_in Device ground reference for the logic side and RS-232 signal common.
16 VCC power_in +5V supply input (4.5V to 5.5V range). Typical ICC is 5mA (MAX232) / 8mA typical no-load. Decouple to GND with a capacitor equal to C1 (1.0µF for MAX232, 0.1µF for MAX232A) placed close to the device.
