Key Features

  • Quad 2-input Schmitt-trigger NAND gates with built-in hysteresis for noise-immune switching in noisy environments
  • Wide supply voltage range compatible with the 4000 CMOS family, operating from 3V to 18V for flexible system integration
  • 14-pin DIP package ideal for through-hole prototyping, breadboard evaluation, and legacy industrial equipment repair

Applications

CD4093BCN is commonly used in oscillator and clock generation circuits, where its Schmitt-trigger inputs enable stable square-wave output using only an RC network. It serves as a signal conditioning gate in industrial systems where slow or noisy logic transitions must be cleaned up before reaching microcontroller inputs. The device also finds application in touch-sensor debouncing, relay drivers, and waveform-shaping circuits in audio and instrumentation equipment.

Frequently Asked Questions

How does the Schmitt-trigger input of CD4093BCN improve noise immunity compared to standard NAND gates?

CD4093BCN Schmitt-trigger inputs feature a defined hysteresis voltage band, typically 0.9V at 5V supply and up to 4V at 15V supply. This hysteresis prevents false triggering when input signals transition slowly or carry noise spikes of less than half the hysteresis band, unlike standard NAND gates that can chatter on noisy slow-rising signals.

Can CD4093BCN generate oscillations and what component values are needed?

Yes, a single NAND gate of CD4093BCN can form a relaxation oscillator using one resistor and one capacitor. With a 100 kΩ resistor and 10 nF capacitor, the oscillation frequency is approximately 1 kHz at 5V supply. This makes CD4093BCN a low-cost clock source for simple timing circuits without requiring a dedicated oscillator IC.

What output current does CD4093BCN provide and which loads can it directly drive?

CD4093BCN maximum output low current is 0.36 mA at the rated supply voltage. This level is sufficient to drive standard CMOS and TTL-compatible inputs, small LEDs in series with a limiting resistor, and logic-level NPN transistor bases. Higher-current loads such as relays or motors require a buffer transistor between the gate output and the load.

Is CD4093BCN a good replacement for 74HC14 in an existing Schmitt-trigger gate design?

CD4093BCN and 74HC14 both provide Schmitt-trigger inputs but differ: CD4093BCN is a 2-input NAND gate with hysteresis while 74HC14 is a hex inverter. CD4093BCN operates from 3V to 18V supply versus 74HC14's 2V to 6V range, giving it an advantage in 12V or 15V industrial systems. The propagation delay is longer at around 200 ns versus 74HC14's 15 ns at 5V, so it is unsuitable for high-speed logic paths above a few MHz.
