CD4085BM from Texas Instruments, in a SOIC-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 A1 input Data input A of the first AND gate in AOI gate 1. Combined with B1 into the first 2-input AND of AOI 1. CMOS logic input (VIL max 1.5/3/4 V and VIH min 3.5/7/11 V at VDD = 5/10/15 V).
2 B1 input Data input B of the first AND gate in AOI gate 1. Combined with A1 into the first 2-input AND of AOI 1. CMOS logic input.
3 E1 output Output of AOI gate 1. Realizes E1 = INH1 + A1·B1 + C1·D1 (a 3-input NOR of INHIBIT1 with the two AND products A1·B1 and C1·D1). Standardized symmetrical CMOS output.
4 E2 output Output of AOI gate 2. Realizes E2 = INH2 + A2·B2 + C2·D2 (3-input NOR of INHIBIT2 with the two AND products A2·B2 and C2·D2). Standardized symmetrical CMOS output.
5 A2 input Data input A of the first AND gate in AOI gate 2. Combined with B2 into the first 2-input AND of AOI 2. CMOS logic input.
6 B2 input Data input B of the first AND gate in AOI gate 2. Combined with A2 into the first 2-input AND of AOI 2. CMOS logic input.
7 VSS power_in Negative supply / ground reference for the device. Absolute maximum input voltage referenced to VSS is -0.5 V to VDD+0.5 V.
8 C2 input Data input C of the second AND gate in AOI gate 2. Combined with D2 into the second 2-input AND of AOI 2. CMOS logic input.
9 D2 input Data input D of the second AND gate in AOI gate 2. Combined with C2 into the second 2-input AND of AOI 2. CMOS logic input.
10 INHIBIT1 input Inhibit control for AOI gate 1. When high, forces E1 low regardless of the A1/B1/C1/D1 inputs (INH1 appears in the NOR term of E1 = INH1 + A1·B1 + C1·D1). CMOS logic input.
11 INHIBIT2 input Inhibit control for AOI gate 2. When high, forces E2 low regardless of the A2/B2/C2/D2 inputs (INH2 appears in the NOR term of E2 = INH2 + A2·B2 + C2·D2). CMOS logic input.
12 C1 input Data input C of the second AND gate in AOI gate 1. Combined with D1 into the second 2-input AND of AOI 1. CMOS logic input.
13 D1 input Data input D of the second AND gate in AOI gate 1. Combined with C1 into the second 2-input AND of AOI 1. CMOS logic input.
14 VDD power_in Positive supply. Recommended supply-voltage range 3 V to 18 V; absolute maximum -0.5 V to 20 V. Parametric ratings characterized at 5 V, 10 V, and 15 V.
