CD4093BE from Texas Instruments, 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	1A	input	Gate 1 Schmitt-trigger input A. Together with pin 2 (B), drives NAND gate 1 whose output appears on pin 3 (J = A·B). Hysteresis ~0.9 V @ 5 V, ~2.3 V @ 10 V. Input current ±0.1 uA max.
2	1B	input	Gate 1 Schmitt-trigger input B. Paired with pin 1 (A) to form NAND gate 1; output on pin 3.
3	1J	output	Gate 1 NAND output, J = NAND(A,B) (datasheet notation 'J = A·B' denoting the NAND). CMOS symmetrical output; IOL/IOH min 0.51 mA @ 5 V, 1.3 mA @ 10 V, 3.4 mA @ 15 V.
4	2K	output	Gate 2 NAND output, K = NAND(C,D). Symmetrical CMOS output drive.
5	2C	input	Gate 2 Schmitt-trigger input C. Paired with pin 6 (D) to drive NAND gate 2 whose output is pin 4 (K).
6	2D	input	Gate 2 Schmitt-trigger input D. Paired with pin 5 (C) for NAND gate 2.
7	VSS	power_in	Negative supply / ground reference. All voltages are referenced to VSS. Tie to 0 V for single-supply operation.
8	3E	input	Gate 3 Schmitt-trigger input E. Paired with pin 9 (F) to drive NAND gate 3 whose output is pin 10 (L).
9	3F	input	Gate 3 Schmitt-trigger input F. Paired with pin 8 (E) for NAND gate 3.
10	3L	output	Gate 3 NAND output, L = NAND(E,F). Symmetrical CMOS output drive.
11	4M	output	Gate 4 NAND output, M = NAND(G,H). Symmetrical CMOS output drive.
12	4G	input	Gate 4 Schmitt-trigger input G. Paired with pin 13 (H) to drive NAND gate 4 whose output is pin 11 (M).
13	4H	input	Gate 4 Schmitt-trigger input H. Paired with pin 12 (G) for NAND gate 4.
14	VDD	power_in	Positive supply. Recommended operating range 3 V to 18 V (absolute max −0.5 V to +20 V referenced to VSS). Quiescent supply current typ 0.02 uA at 25 °C.
