MC14001UBDG from onsemi, 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 IN1A input Input 1 of NOR gate A. CMOS logic input; VIH >= 4.0/8.0/12.5 V at VDD = 5/10/15 V, VIL <= 1.0/2.0/2.5 V at same VDD. Input current typically ~10 fA (max +/-0.1 uA at 25 C).
2 IN2A input Input 2 of NOR gate A. CMOS logic input with double-diode ESD protection to VDD/VSS. Unused NOR-gate inputs must be tied to VSS.
3 OUTA output Output of NOR gate A (= NOT(IN1A OR IN2A)). CMOS push-pull output; VOH >= VDD-0.05 V, VOL <= 0.05 V (Vin = VDD or 0). Drives 2 LSTTL loads / 1 LS Schottky TTL load.
4 OUTB output Output of NOR gate B (= NOT(IN1B OR IN2B)). CMOS push-pull output; source current typ 1.7 mA at VDD=5 V / VOH=2.5 V, sink current typ 0.88 mA at VDD=5 V / VOL=0.4 V (25 C).
5 IN1B input Input 1 of NOR gate B. High-impedance CMOS input, typ Cin = 5 pF.
6 IN2B input Input 2 of NOR gate B. CMOS logic input with double-diode ESD protection; Vin must remain within VSS <= Vin <= VDD.
7 VSS power_in Negative supply / ground reference for all four gates. Typically tied to 0 V. Maximum VDD-VSS supply differential is 18 V.
8 IN1C input Input 1 of NOR gate C. CMOS logic input; see VIL/VIH table for switching thresholds.
9 IN2C input Input 2 of NOR gate C. CMOS logic input with double-diode ESD protection to VDD/VSS.
10 OUTC output Output of NOR gate C (= NOT(IN1C OR IN2C)). CMOS push-pull output.
11 OUTD output Output of NOR gate D (= NOT(IN1D OR IN2D)). CMOS push-pull output.
12 IN1D input Input 1 of NOR gate D. High-impedance CMOS input.
13 IN2D input Input 2 of NOR gate D. CMOS logic input with double-diode ESD protection.
14 VDD power_in Positive supply for all four NOR gates. DC supply range 3.0 V to 18 V (absolute max -0.5 V to +18.0 V referenced to VSS). Quiescent current typ 0.5 nA / max 0.25 uA at VDD = 5 V (25 C).
