HMAX232DR

HXY MOSFET · RS232 ICs · SOP-16

HMAX232DR from HXY MOSFET, in a SOP-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 terminal of the charge-pump C1 capacitor, which connects across C1- in the typical application circuit (1.0 µF shown).
2	V+	power_out	Positive voltage (V+) generated internally by the charge pump, which sets the RS-232 transmitter high output level; absolute maximum rating is VCC-0.3 V per the ratings table.
3	C1-	passive	Negative terminal of the charge-pump C1 capacitor.
4	C2+	passive	Positive terminal of the charge-pump C2 capacitor.
5	C2-	passive	Negative terminal of the charge-pump C2 capacitor.
6	V-	power_out	Negative voltage (V-) generated internally by the charge pump; the transmitter low output limit is -14 V in the absolute maximum ratings.
7	T2OUT	output	RS-232 driver output (RS-232 levels); transmitter output short-circuit current is limited to ±60 mA in the recommended operating conditions.
8	R2IN	input	RS-232 receiver input (RS-232 levels), with a receiver input voltage range of -30 V to 30 V.
9	R2OUT	output	RS-232 receiver output at TTL/CMOS levels.
10	T2IN	input	RS-232 driver input at TTL/CMOS levels; the transmitter input voltage range is 0 V to VCC.
11	T1IN	input	RS-232 driver input at TTL/CMOS levels; the transmitter input voltage range is 0 V to VCC.
12	R1OUT	output	RS-232 receiver output at TTL/CMOS levels.
13	R1IN	input	RS-232 receiver input (RS-232 levels), with a receiver input voltage range of -30 V to 30 V.
14	T1OUT	output	RS-232 driver output (RS-232 levels); transmitter output short-circuit current is limited to ±60 mA in the recommended operating conditions.
15	GND	power_in	Ground reference for the device.
16	VCC	power_in	Supply voltage input; absolute maximum rating is -0.3 V to 6.0 V.
