- 4000-series CMOS family supporting supply voltages from 3 V to 18 V, enabling use in legacy and battery-powered systems
- 14-pin DIP package with 6.8 mA sink current and 50 pF load capacity, convenient for breadboard prototyping and through-hole production
Applications
The CD4093BEE4 is widely used to build simple RC oscillators by connecting the Schmitt trigger output back to the input through a resistor and capacitor, generating square waves from a few hertz to several hundred kilohertz depending on the RC values. Its wide supply range of 3 V to 18 V makes it suitable for battery-operated remote controls, alarm circuits, and timer applications where supply voltage is unregulated. Each gate also serves as a signal conditioner on slow-rising analog signals such as temperature sensor outputs, converting them to crisp digital edges for microcontroller GPIO inputs.

Frequently Asked Questions
How does the Schmitt trigger hysteresis in CD4093BEE4 enable a simple RC oscillator without additional components?
Connecting a resistor between the output and input and a capacitor from the input to ground creates a relaxation oscillator: the Schmitt hysteresis forces the output to toggle when the capacitor charge crosses the VT+ threshold, then discharge through VT-, cycling continuously. At 10 V supply a typical 100 kΩ resistor and 10 nF capacitor produce approximately 1 kHz square wave output using only the CD4093BEE4 gate and 2 passive components.
What supply voltage range does CD4093BEE4 support, and how does it compare to HC-family NAND gates at 3.3 V?
The 4000-series CD4093BEE4 operates from 3 V to 18 V, while HC-family parts are limited to 2 V to 6 V. This means CD4093BEE4 can directly drive 12 V relays or incandescent indicators with its open-drain configuration at 12 V supply, whereas an HC gate would require a level shifter. At 3.3 V supply both families function, but CD4093BEE4 is slower (typical propagation 50–100 ns at 5 V versus 7 ns for HC).
How many NAND gate functions does CD4093BEE4 provide, and can all 4 gates be used simultaneously as independent oscillators?
CD4093BEE4 contains 4 independent 2-input NAND Schmitt trigger gates sharing only power and ground pins, so all 4 can simultaneously operate as separate RC oscillators with different RC networks. Each gate sinks up to 6.8 mA at VOL spec and drives a 50 pF load, adequate for four independent oscillator or debounce channels on a single 14-pin DIP IC, reducing component count significantly in multi-channel timer designs.
For a through-hole prototyping board, how does the DIP-14 package of CD4093BEE4 simplify breadboard assembly?
The 14-pin 2.54 mm pitch DIP package fits directly on standard breadboards and perfboards without adapters, allowing rapid prototyping by hand-inserting and wiring. Each gate in CD4093BEE4 is accessible on adjacent pin pairs, making RC oscillator circuits testable with just 1 resistor and 1 capacitor per gate without soldering. This physical convenience makes it a staple in educational lab kits and hobbyist analog-to-digital signal conditioning experiments at supply voltages from 5 V to 15 V.
