LMH6642MAX from Texas Instruments, in a SOIC-8. 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	N/C	unconnected	No internal connection. Leave floating or tie to a quiet net; do not use as a signal via.
2	-IN	input	Inverting input of the voltage-feedback op-amp. High-impedance node used for the feedback network; input common-mode range extends to 0.5 V below V- and to within 1 V of V+.
3	+IN	input	Non-inverting input of the voltage-feedback op-amp. High-impedance node; input common-mode range extends to 0.5 V below V- and 1 V below V+.
4	V-	power_in	Negative supply rail. Tie to GND for single-supply operation or to a negative rail for split-supply. Total supply (V+ - V-) range is 2.7 V to 12.8 V (13.5 V abs max).
5	N/C	unconnected	No internal connection. Leave floating or tie to a quiet net.
6	OUTPUT	output	Rail-to-rail amplifier output. Swings to within 40 mV of either supply, sources/sinks up to ~75 mA linear (short-circuit +115 mA to 145 mA). Output is short-circuit protected (see abs-max short duration).
7	V+	power_in	Positive supply rail. Decouple locally with 0.1 µF + bulk cap. Total supply (V+ - V-) 2.7-12.8 V; supply current is typically 2.7 mA.
8	N/C	unconnected	No internal connection. Leave floating or tie to a quiet net.
