MAX3232IPWRG4

Texas Instruments · RS232 ICs · TSSOP-16

MAX3232IPWRG4 from Texas Instruments, in a TSSOP-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 lead of the C1 charge-pump capacitor; its value is selected by VCC per Table 9-1 (0.1 µF at 3.3 V, 0.047 µF at 5 V).
2 V+ power_out Positive charge-pump output used only for its storage capacitor; the absolute maximum on V+ is -0.3 V to 7 V.
3 C1- passive Negative lead of the C1 charge-pump capacitor.
4 C2+ passive Positive lead of the C2 charge-pump capacitor; C2 to C4 are 0.1 µF at 3.3 V, 0.33 µF at 5 V (Table 9-1).
5 C2- passive Negative lead of the C2 charge-pump capacitor.
6 V- power_out Negative charge-pump output used only for its storage capacitor; the absolute range on V- is -7 V to 0.3 V.
7 DOUT2 output RS-232 line driver output to the remote RS-232 system, specified at VOH of at least 5 V and VOL of at most -5 V with a 3 kΩ load to GND.
8 RIN2 input RS-232 line receiver input from the remote RS-232 system, with an input voltage range of -25 V to 25 V and an internal 3 kΩ to 7 kΩ input resistance.
9 ROUT2 output Logic data output to the UART, with VOH of at least VCC - 0.6 V at IOH = -1 mA.
10 DIN2 input Logic data input from the UART, which must be held at a valid high or low level; VIH is 2 V at 3.3 V VCC or 2.4 V at 5 V VCC and VIL is at most 0.8 V.
11 DIN1 input Logic data input from the UART, which must be held at a valid high or low level; VIH is 2 V at 3.3 V VCC or 2.4 V at 5 V VCC and VIL is at most 0.8 V.
12 ROUT1 output Logic data output to the UART, with VOH of at least VCC - 0.6 V at IOH = -1 mA.
13 RIN1 input RS-232 line receiver input from the remote RS-232 system, with an input voltage range of -25 V to 25 V and an internal 3 kΩ to 7 kΩ input resistance.
14 DOUT1 output RS-232 line driver output to the remote RS-232 system, specified at VOH of at least 5 V and VOL of at most -5 V with a 3 kΩ load to GND.
15 GND power_in Ground reference for all device voltages; all absolute maximum and operating voltages are referenced to GND.
16 VCC power_in Supply voltage input, connected to an external 3 V to 5.5 V supply (absolute maximum -0.3 V to 6 V).
