RS722PXM from Jiangsu RUNIC 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	OUTA	output	Output of channel A; the output swings rail to rail and is continuous-short-circuit protected, with output currents beyond 0.5V outside the supply rails limited to ±150mA.
2	-INA	input	Inverting input of channel A; input signals must stay within (V-)-0.5V to (V+)+0.5V, and inputs swinging more than 0.5V beyond the rails should be current-limited to 10mA or less.
3	+INA	input	Noninverting input of channel A; input signals must stay within (V-)-0.5V to (V+)+0.5V, and inputs swinging more than 0.5V beyond the rails should be current-limited to 10mA or less.
4	V-	power_in	Negative (lowest) power supply pin; the supply range is 2.5V to 5.5V single-supply or ±1.25V to ±2.75V dual-supply, with an absolute maximum supply of 7V.
5	+INB	input	Noninverting input of channel B; input signals must stay within (V-)-0.5V to (V+)+0.5V, and inputs swinging more than 0.5V beyond the rails should be current-limited to 10mA or less.
6	-INB	input	Inverting input of channel B; input signals must stay within (V-)-0.5V to (V+)+0.5V, and inputs swinging more than 0.5V beyond the rails should be current-limited to 10mA or less.
7	OUTB	output	Output of channel B; the output swings rail to rail and is continuous-short-circuit protected, with output currents beyond 0.5V outside the supply rails limited to ±150mA.
8	V+	power_in	Positive (highest) power supply pin; the supply range is 2.5V to 5.5V single-supply or ±1.25V to ±2.75V dual-supply, with an absolute maximum supply of 7V.
