SY100EPT22VKG from Microchip Tech, in a MSOP-8. 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	Q0	output	Differential LVPECL output, true output of channel 0, which defaults HIGH when D0 is open.
2	/Q0	output	Differential LVPECL output, complement of Q0, which defaults LOW when D0 is open.
3	Q1	output	Differential LVPECL output, true output of channel 1, which defaults HIGH when D1 is open.
4	/Q1	output	Differential LVPECL output, complement of Q1, which defaults LOW when D1 is open.
5	GND	power_in	Ground; the device needs only a single positive supply and no negative supply.
6	D1	input	LVTTL/LVCMOS input for channel 1 with VIH min 2.0V and VIL max 0.8V, translated to differential LVPECL on Q1 and /Q1.
7	D0	input	LVTTL/LVCMOS input for channel 0 with VIH min 2.0V and VIL max 0.8V, translated to differential LVPECL on Q0 and /Q0.
8	VCC	power_in	Positive supply, 3.3V ±5% or 5.0V ±5% (absolute maximum -0.5 to +7.0V), with ICC max 25mA.
