SY89327LMG-TR from Microchip Tech, in a MLF-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	NC	unconnected	No connect.
2	IN	input	Differential signal input that accepts AC- or DC-coupled signals as small as 100mV; external termination is required.
3	/IN	input	Complement of the differential signal input that accepts AC- or DC-coupled signals as small as 100mV; external termination is required.
4	NC	unconnected	No connect.
5	GND	power_in	Ground pin; the ground pin and exposed pad must be connected to the same ground plane.
6	/Q	output	Complement differential LVPECL output, which must be terminated with 50Ω to VCC-2V.
7	Q	output	True differential LVPECL output (100k temperature-compensated LVPECL compatible), which must be terminated with 50Ω to VCC-2V.
8	VCC	power_in	Positive power supply, 3.0V to 3.6V per the operating ratings; bypass with 0.1µF
9	EP	passive	Exposed pad (from the footprint; not named in the datasheet pin table).
