DS90LT012ATMF from Texas Instruments, 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	VDD	power_in	Positive supply. Recommended 2.7V-3.6V (3.3V typ). Bypass locally with a 0.1 µF ceramic. IDD ≈ 5.4 mA typical (no load).
2	GND	power_in	Device ground reference for supply and signal returns. Tie to the board's solid ground plane.
3	IN+	input	Non-inverting LVDS differential input. Accepts LVDS/BLVDS/LVPECL small-swing signals; allowed input range −0.05V to VDD−0.3V (see Electrical Characteristics). Internally terminated to IN− through the integrated 102Ω resistor on the LT variant.
4	IN-	input	Inverting LVDS differential input. Same electrical constraints as IN+. Together with IN+ forms the ~100 mV threshold differential receiver; VTH ≤ 0 mV, VTL ≥ −100 mV.
5	TTL OUT	output	3V CMOS/TTL push-pull receiver output. VOH ≥ 2.4V @ IOH = −0.4 mA; VOL ≤ 0.5V @ IOL = 2 mA. Output is HIGH when (IN+ − IN−) ≥ 0V or fail-safe (open/short/terminated), LOW when (IN+ − IN−) ≤ −0.1V.
