CD4011BNSR

CD4011BNSR is a quad 2-input NAND gate IC in the CMOS CD4000B family. It contains four independent NAND gates in one package.
- Function: Each gate outputs LOW only when both inputs are HIGH; otherwise, the output is HIGH.
- Supply: Typical Vcc range is 3–15 V (often used at 5 V, 9 V, etc.); CMOS inputs have high impedance and very low static power.
- Pinout (DIP14): Pin 14 = VDD, Pin 7 = VSS. Gate 1: inputs at pins 1 and 2, output at pin 3. Gate 2: inputs 4 and 5, output 6. Gate 3: inputs 9 and 10, output 8. Gate 4: inputs 12 and 13, output 11.
- Packaging: “NSR” denotes a specific package/style variant (e.g., plastic DIP/narrow form).
- Tips: decouple the supply with a capacitor, avoid floating inputs, and respect current limits.
Use for basic logic, gating, timing, debouncing, and simple combinational circuits.
