ICL8038N from HGSEMI, in a DIP-14. 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	SINE WAVE ADJ	input	Sine wave distortion adjust. External potentiometer between this pin and V- trims the sine wave symmetry/distortion.
2	SINE WAVE OUT	output	Sine wave output. Low-impedance analog waveform output, typical amplitude 0.22 x (V+ - V-).
3	TRIANGLE OUT	output	Triangle wave output. Analog output, amplitude typically 0.33 x (V+ - V-).
4	DUTY CYCLE/FREQ ADJ A	input	Duty cycle / frequency adjust input A. Timing resistor RA sets the rising slope current of the timing capacitor.
5	DUTY CYCLE/FREQ ADJ B	input	Duty cycle / frequency adjust input B. Timing resistor RB sets the falling slope current; combined with RA controls duty cycle from 2% to 98%.
6	V+	power_in	Positive supply. Single supply +10 V to +30 V, or dual supply +/-5 V to +/-15 V.
7	FM BIAS	output	FM bias voltage. Internal reference used to set the nominal frequency; can be connected to pin 8 for basic (non-swept) operation.
8	FM SWEEP IN	input	FM sweep / VCO control input. Applying a voltage relative to V+ modulates the output frequency for FM or sweep operation.
9	SQUARE WAVE OUT	output	Square wave output. Open-collector output; requires an external pull-up resistor to V+ (or to a separate supply for level shifting).
10	TIMING CAP	passive	Timing capacitor connection. External capacitor C from this pin to V- sets the operating frequency together with RA and RB.
11	V-/GND	power_in	Negative supply / ground. Connect to ground for single-supply operation or to the negative rail for dual-supply operation.
12	SINE WAVE ADJ	input	Sine wave distortion adjust (second tap). Companion to pin 1 for full symmetry trim of the sine shaper.
13	NC	unconnected	No internal connection.
14	NC	unconnected	No internal connection.
