Pinout

Pin Name Type Function
1 Y1 output Output of NOR gate 1. Y1 = NOT(A1 + B1). CMOS push-pull output; drives up to 10 LSTTL loads with
2 A1 input A-input of NOR gate 1. High-impedance CMOS input (input leakage ≤ 1.0 µA). Unused inputs must be tied to GND or VCC.
3 B1 input B-input of NOR gate 1. High-impedance CMOS input (input leakage ≤ 1.0 µA). Unused inputs must be tied to GND or VCC.
4 Y2 output Output of NOR gate 2. Y2 = NOT(A2 + B2). CMOS push-pull output; drives up to 10 LSTTL loads with
5 A2 input A-input of NOR gate 2. High-impedance CMOS input (input leakage ≤ 1.0 µA). Unused inputs must be tied to GND or VCC.
6 B2 input B-input of NOR gate 2. High-impedance CMOS input (input leakage ≤ 1.0 µA). Unused inputs must be tied to GND or VCC.
7 GND power_in Ground reference (0 V). Return for VCC. Absolute max supply current between VCC and GND is 50 mA.
8 A3 input A-input of NOR gate 3. High-impedance CMOS input (input leakage ≤ 1.0 µA). Unused inputs must be tied to GND or VCC.
9 B3 input B-input of NOR gate 3. High-impedance CMOS input (input leakage ≤ 1.0 µA). Unused inputs must be tied to GND or VCC.
10 Y3 output Output of NOR gate 3. Y3 = NOT(A3 + B3). CMOS push-pull output; drives up to 10 LSTTL loads with
11 A4 input A-input of NOR gate 4. High-impedance CMOS input (input leakage ≤ 1.0 µA). Unused inputs must be tied to GND or VCC.
12 B4 input B-input of NOR gate 4. High-impedance CMOS input (input leakage ≤ 1.0 µA). Unused inputs must be tied to GND or VCC.
13 Y4 output Output of NOR gate 4. Y4 = NOT(A4 + B4). CMOS push-pull output; drives up to 10 LSTTL loads with
14 VCC power_in Positive supply voltage. Recommended operating range 2.0 V to 6.0 V (absolute max 7.0 V). Bypass with a 0.1 µF ceramic capacitor close to the pin.
