Key Features
- Quad 2-input NAND Schmitt trigger with built-in hysteresis rejects noise spikes on slow or noisy digital input signals
- Wide operating voltage range of the 4000-series CMOS family allows use from 3 V to 18 V power supplies without redesign
- 14-pin ceramic DIP (R-GDIP-T14) package provides enhanced reliability in high-temperature or harsh-environment industrial applications
Applications
CD4093BF is widely used in signal conditioning circuits where noisy or slowly transitioning digital signals must be converted to clean logic levels without spurious toggling. Its Schmitt trigger inputs make it ideal for RC oscillator circuits, switch debouncing networks, and waveform shaping stages in industrial control and consumer electronics. The 4000-series CMOS compatibility also makes it a reliable choice for battery-powered designs requiring low quiescent current and broad supply voltage tolerance.

Frequently Asked Questions
How does CD4093BF's Schmitt trigger hysteresis improve noise immunity versus standard NAND gates?
CD4093BF incorporates Schmitt trigger inputs with built-in hysteresis on each of its 4 NAND gates, creating separate rising and falling input voltage thresholds. This hysteresis band — typically several hundred millivolts wide across the 4000-series supply range — prevents multiple output transitions caused by noisy or slowly ramping input signals. In contrast, standard NAND gates with a single threshold voltage would chatter on noisy inputs, causing false logic transitions.
What supply voltage range does CD4093BF support and how does it fit into mixed 5 V and 12 V industrial designs?
CD4093BF operates across the full 4000-series CMOS voltage range, typically 3 V to 18 V, making it usable in both 5 V logic systems and 12 V industrial control circuits without extra regulators. Its 1.5 mA maximum output low current (I_OL) is sufficient to directly drive standard CMOS inputs and most LED indicator circuits. Mixed-voltage industrial panels can use a single CD4093BF to interface 12 V field sensors to 5 V microcontrollers through appropriate resistor dividers.
When is CD4093BF the right choice for building a simple RC oscillator versus using a dedicated timer IC?
CD4093BF's Schmitt trigger NAND gates combined with an external resistor and 50 pF to several nF capacitor form a simple, low-cost RC oscillator without a dedicated timer IC. The oscillation frequency depends on the RC time constant and the gate's hysteresis thresholds, covering audio and low-frequency ranges up to several hundred kHz. This approach reduces BOM count and cost in designs where precise frequency is not critical, such as heartbeat LED flashers or low-frequency clock sources.
How long will CD4093BF remain available and is it RoHS-compliant for new designs?
CD4093BF has a YTEOL (years to end of life) of 15 years, making it a safe choice for long-lifecycle industrial and medical equipment designs. It carries a Pb-free, RoHS-compliant designation per its JESD-609 e0 code. The ceramic 14-pin DIP package (R-GDIP-T14) further supports applications in extended-temperature environments, as ceramic packages withstand higher thermal stress than standard plastic DIP alternatives.
