FIN1002M5X from onsemi, in a SOT-23-5. 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	VCC	power_in	Power supply input. Recommended operating range 3.0 V to 3.6 V (nominal 3.3 V). Absolute maximum 4.6 V. Typical ICC ~4 mA (7 mA max).
2	GND	power_in	Ground reference for the IC. Connect to system ground.
3	RIN+	input	Non-inverting LVDS differential receiver input. Differential input threshold ±100 mV. Input voltage range 0 to VCC. Over-voltage tolerant; fail-safe HIGH output when open/shorted/terminated.
4	RIN-	input	Inverting LVDS differential receiver input. Differential input threshold ±100 mV. Input voltage range 0 to VCC. Over-voltage tolerant; fail-safe HIGH output when open/shorted/terminated.
5	ROUT	output	LVTTL single-ended data output. VOH ≥ 2.4 V @ IOH = -8 mA; VOL ≤ 0.5 V @ IOL = 8 mA. High-impedance when VCC < 1.5 V.
