Texas Instruments CD4011BE Quad 2-Input NAND Gate IC, PDIP-14, 18V

The Texas Instruments CD4011BE is a versatile quad 2-input CMOS NAND gate integrated circuit, providing designers with a reliable and efficient direct implementation of the NAND logic function. It complements the established CD4000 series family of CMOS gates, offering robust performance for a wide array of digital logic applications.

All inputs and outputs on this IC are fully buffered, enhancing noise immunity and preventing loading effects on preceding logic stages. This buffering contributes to the device's standardised symmetrical output characteristics, ensuring consistent signal integrity. The CD4011BE operates over a broad voltage supply range from 3V to 18V, making it suitable for both low-power and standard logic level projects.

Key Performance Features

• Low Power Consumption: Exhibits an exceptionally low maximum input current of just 1µA at 18V across the full operating temperature range, conserving energy in battery-operated or power-sensitive designs.
• Wide Temperature Range: Capable of reliable operation from -55°C to +125°C, suitable for industrial, automotive, and harsh environment applications.
• Tested Reliability: Every device is 100% tested for quiescent current at 20V, guaranteeing quality and performance consistency.
• Robust Output: Can source or sink up to 6.8mA of output current, providing adequate drive capability for LEDs, relays, or other logic inputs.

Housed in a durable 14-pin Plastic Dual In-line Package (PDIP), this IC is easy to handle and ideal for prototyping on breadboards or for use in through-hole PCB designs. With a typical propagation delay of 60ns (at a 10V supply and 50pF load), it delivers solid performance for general-purpose logic tasks, clock generation, and waveform shaping.
