LTV-333J-TA1-B from Lite On, 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	VS	power_in	Input-side ground (input ground reference for the LED driver / FAULT logic).
2	VCC1	power_in	Positive input supply voltage, 3.3 V to 5.5 V.
3	FAULT	output	Fault output. Changes from high impedance to logic low within 5 us if the DESAT pin voltage exceeds an internal reference of 7 V. Open-collector output allowing multiple LTV-333J FAULT outputs to be wire-OR'd into a single fault bus to a microcontroller.
4	VS	power_in	Input-side ground (second VS pin, tied to input ground reference).
5	CATHODE	input	Cathode of the input LED (LED1 drive input). Drive with the input signal referenced to the ANODE pins to command the gate driver output.
6	ANODE	input	Anode of the input LED (LED1 drive input).
7	ANODE	input	Anode of the input LED (second ANODE pin, parallel with pin 6).
8	CATHODE	input	Cathode of the input LED (second CATHODE pin, parallel with pin 5).
9	VEE	power_in	Output-side negative supply (typically IGBT emitter-referenced negative rail). Same net as pin 12.
10	VCLAMP	output	Active Miller clamp output. Sinks Miller current from the IGBT gate to VEE during the off state to suppress parasitic turn-on.
11	VOUT	output	Gate drive voltage output. Sources/sinks up to 5.0 A peak (4.0 A minimum) to drive the IGBT/MOSFET gate.
12	VEE	power_in	Output-side negative supply (typically IGBT emitter-referenced negative rail). Same net as pin 9.
13	VCC2	power_in	Positive output supply voltage. Wide VCC operating range 15 to 30 V.
14	DESAT	input	Desaturation voltage input. When the DESAT voltage exceeds the internal 6.5 V reference while the IGBT is on, FAULT transitions from high impedance to logic low within 5 us and the output performs a soft turn-off.
15	VLED	passive	LED anode test pin. Must be left unconnected for guaranteed data-sheet performance (used for optical coupling testing only).
16	VE	power_in	Common IGBT emitter output supply reference (Kelvin-emitter return for the gate driver output stage).
