What are the key features of CD4081BME4?
- Quad 2-input AND gate with wide 3 V to 18 V supply range enables direct interfacing between 5 V and 12 V logic domains without level-shifters
- 4000-series CMOS technology delivers high input impedance and excellent noise immunity for reliable logic operation in electrically noisy industrial environments
- 14-pin SOIC package with 50 pF rated load capacitance supports fan-out to multiple downstream logic gates without additional buffers
What is CD4081BME4 used for?
The CD4081BME4 is widely used in digital logic systems for control masking, enable/disable functions, and signal gating where four independent AND operations are required on a single IC. Its 3 V to 18 V supply compatibility makes it directly applicable to both 5 V TTL-compatible systems and 12 V industrial PLC logic without additional voltage translation. The device is equally effective in timer circuits, frequency multipliers, and relay-drive logic in automotive body-control and building-automation panels.

Frequently Asked Questions
Over what supply voltage range does CD4081BME4 operate, and which logic families can it interface with directly?
The CD4081BME4 operates from 3 V to 18 V VDD, making it directly compatible with 5 V TTL logic, 3.3 V CMOS outputs with pull-up, and 12 V or 15 V industrial logic levels. The 4000-series high input impedance also allows interfacing with LSTTL and HC-series outputs across a common 5 V supply without additional level-shift components.
How many AND gate functions does CD4081BME4 provide, and what is the output drive current?
The CD4081BME4 contains 4 independent 2-input AND gates, each capable of sinking 6.8 mA at the output. This current rating is sufficient to directly drive indicator LEDs through a series resistor, bipolar transistor bases, or the inputs of multiple downstream CMOS gate inputs without needing a dedicated buffer IC.
In a microcontroller enable circuit, how does the AND gate structure of CD4081BME4 allow conditional signal routing?
By connecting the enable line from the MCU to one input and the signal to be gated to the other input of a CD4081BME4 AND gate, the output passes the signal only when both inputs are high. With 4 gates per package, a single CD4081BME4 can simultaneously gate 4 independent channels—such as 4 PWM outputs—from a single hardware enable signal, reducing component count versus discrete transistor switches.
How does the 14-pin SOIC package of CD4081BME4 compare in assembly cost to a through-hole DIP-14 alternative?
The SOIC-14 package used in the CD4081BME4 is compatible with standard SMT pick-and-place assembly on PCBs with 1.27 mm pitch pads, offering lower per-unit placement cost and a roughly 40% smaller board footprint compared with a DIP-14 package that requires through-hole drilling and hand or wave soldering. The SMT format also supports automated optical inspection for high-volume production runs.
