TLC2272AQDRQ1 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	1OUT	output	Output, channel 1. Rail-to-rail CMOS output; can source/sink up to ±50 mA (absolute max) and is short-circuit protected to either supply rail.
2	1IN-	input	Inverting input, channel 1. High-impedance CMOS input (10^12 Ω differential); common-mode range includes the negative rail (VDD- - 0.3 V to VDD+ - 1.5 V).
3	1IN+	input	Noninverting input, channel 1. High-impedance CMOS input (10^12 Ω differential); 1 pA typical input bias current; common-mode range includes the negative rail.
4	VDD-	power_in	Negative (lowest) supply. In single-supply operation this pin is tied to GND; in split-supply operation accepts down to -8 V. Total supply range ±2.2 V to ±8 V.
5	2IN+	input	Noninverting input, channel 2. High-impedance CMOS input (10^12 Ω differential); 1 pA typical input bias current; common-mode range includes the negative rail.
6	2IN-	input	Inverting input, channel 2. High-impedance CMOS input (10^12 Ω differential); common-mode range includes the negative rail (VDD- - 0.3 V to VDD+ - 1.5 V).
7	2OUT	output	Output, channel 2. Rail-to-rail CMOS output; can source/sink up to ±50 mA (absolute max) and is short-circuit protected to either supply rail.
8	VDD+	power_in	Positive (highest) supply. Single-supply range 2.2 V to 8 V (referenced to VDD-/GND); split-supply range up to ±8 V. Bypass with 0.1 µF close to the pin.
