CD4011BNSR

CD4011BNSR is a CMOS quad 2-input NAND gate IC (part of the 4000B family). Key points:
- Four independent NAND gates in one 14-pin package; each gate has two inputs and one output.
- Wide supply range: typically 3 V to 15 V (works well at 5 V for most logic projects).
- CMOS with very high input impedance and very low static power consumption.
- Output can drive modest loads; suitable for many digital logic applications. Input thresholds are CMOS levels (not guaranteed to be TTL-compatible, depending on supply and load).
- Slower than modern TTL/CMOS gates but adequate for many hobby and embedded circuits; propagation delay varies with Vdd and temperature.
- Commonly available in DIP-14 and various surface-mount packages; suffixes like NSR denote package/ RoHS options.
- Practical uses: building logic nets, simple combinational circuits, debouncing, timing/conditioning with other CMOS parts; you can realize NOT/AND/OR functions by wiring NANDs and inverters.
Note: Check the specific datasheet for exact pinout, electrical specs, and packaging details for CD4011BNSR.

CD4011BNSR features (quad 2-input NAND gates):
- Four independent 2-input NAND gates
- CMOS static logic; very low quiescent current
- Wide operating voltage: 3V to 15V (absolute max ~18V)
- Outputs swing to near rails; can drive moderate loads
- High noise immunity; robust ESD protection typical of CD4000 family
- Input thresholds around mid-supply (CMOS compatible with CMOS/TTL interfacing ranges)
- Industrial temperature range (often -40°C to +125°C)
- Available in 14-pin packages (DIP/SOP variants; NSR suffix indicates RoHS-compliant packaging)
- Propagation delay varies with Vdd and load (generally tens to hundreds of nanoseconds)

CD4011BNSR comes in a 14-pin Narrow Small-Outline package (NSR), i.e., a narrow SOIC.

- Pin count: 14 pins (DIP/SOP package variants).
- Function: Quad 2-input NAND gate. Y = NOT(A AND B) for each gate. Pinout (typical): 1=A1, 2=B1, 3=Y1; 4=A2, 5=B2, 6=Y2; 7=GND; 8=A3, 9=B3, 10=Y3; 11=A4, 12=B4, 13=Y4; 14=VDD.

Manufacturer: Nexperia (formerly Philips Semiconductors / part of NXP). Nexperia is a global, Dutch multinational semiconductor company that designs and manufactures discrete components and logic ICs (e.g., CD4000/74xx families) used in electronic devices.
