MAX232EESE-TD

TDSEMIC · RS232 ICs · SOP-16

MAX232EESE-TD from TDSEMIC, in a SOP-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	Terminal for positive charge-pump C1 capacitor (1.0µF external capacitor connected between C1+ and C1-).
2	V+	power_out	Positive voltage generated by the internal charge-pump (typically +10V with 5V supply); 1.0µF reservoir capacitor to GND.
3	C1-	passive	Terminal for negative charge-pump C1 capacitor (1.0µF external capacitor connected between C1+ and C1-).
4	C2+	passive	Terminal for positive charge-pump C2 capacitor (1.0µF external capacitor connected between C2+ and C2-).
5	C2-	passive	Terminal for negative charge-pump C2 capacitor (1.0µF external capacitor connected between C2+ and C2-).
6	V-	power_out	Negative voltage generated by the internal charge-pump (typically -10V with 5V supply); 1.0µF reservoir capacitor to GND.
7	T2OUT	output	RS-232 driver output for transmitter channel 2; output levels comply with RS-232 standard (V+ to V- swing, VOL ≤ -5.2V, VOH ≥ 5.0V typ).
8	R2IN	input	RS-232 receiver input for channel 2; accepts RS-232 levels, VIN range -20V to +20V, input resistance 3.0-7.0 kΩ.
9	R2OUT	output	RS-232 receiver output for channel 2; TTL/CMOS logic-level output (VOL ≤ 0.3V, VOH ≥ 2.4V at 3.2 mA).
10	T2IN	input	RS-232 driver input for transmitter channel 2; accepts TTL/CMOS logic levels, VCC = 4.5-5.5V.
11	T1IN	input	RS-232 driver input for transmitter channel 1; accepts TTL/CMOS logic levels, VCC = 4.5-5.5V.
12	R1OUT	output	RS-232 receiver output for channel 1; TTL/CMOS logic-level output (VOL ≤ 0.3V, VOH ≥ 2.4V at 3.2 mA).
13	R1IN	input	RS-232 receiver input for channel 1; accepts RS-232 levels, VIN range -20V to +20V, input resistance 3.0-7.0 kΩ.
14	T1OUT	output	RS-232 driver output for transmitter channel 1; output levels comply with RS-232 standard (V+ to V- swing, VOL ≤ -5.2V, VOH ≥ 5.0V typ).
15	GND	power_in	Ground reference for all internal circuitry and charge-pump capacitors.
16	VCC	power_in	Supply voltage input; recommended operating range 4.5V to 5.5V, absolute maximum 6.0V; quiescent current typ 1.0 mA at 25°C, max 14.0 mA.
