TLC2652CN from Texas Instruments, in a PDIP-14. 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	CXB	passive	Connection for external nulling capacitor CXB (0.1 µF to 1 µF), returned to VDD− or C RETURN.
2	CXA	passive	Connection for external nulling capacitor CXA (0.1 µF to 1 µF), returned to VDD− or C RETURN.
3	NC	unconnected	No internal connection.
4	IN−	input	Inverting input of the op amp; input voltage limited to ±8 V and differential input to ±16 V.
5	IN+	input	Noninverting input of the op amp; common-mode range includes the negative rail, VDD− to VDD+ −1.9 V.
6	NC	unconnected	No internal connection.
7	VDD−	power_in	Negative supply, absolute maximum −8 V; also the reference for the clock input range and a return for CXA/CXB.
8	C RETURN	passive	Return connection for the external capacitors CXA and CXB, alternative to VDD−.
9	CLAMP	passive	Output clamp, connected to the inverting input to reduce overload recovery time; activates when output is about 1 V from either rail.
10	OUT	output	Amplifier output, up to ±50 mA output current with short-circuit to either supply allowed within dissipation limits.
11	VDD+	power_in	Positive supply, absolute maximum 8 V; operating supply is ±1.9 V to ±8 V.
12	CLK OUT	output	Internal clock output of the chopper control circuitry.
13	CLK IN	input	External clock input, range VDD− to VDD− +5 V with trip point 2.5 V above the negative rail, used when INT/EXT is tied to VDD−.
14	INT/EXT	input	Clock select: leave unconnected for the internal 450-Hz clock, or connect to VDD− to use the external clock on CLK IN.
