Key Features
- Hex Schmitt-trigger inverters providing superior noise immunity compared to standard inverters
- LV logic family: operates at 2.7 V to 3.6 V supply voltage for low-voltage system compatibility
- 14-pin SOIC/SSOP (R-PDSO-G14) compact surface-mount package for space-constrained designs
- RoHS compliant (JESD-609 e4), Pb-free construction meeting global environmental standards
Applications
The SN74LV14ADB is used in signal conditioning circuits where Schmitt-trigger hysteresis is needed to clean up slow or noisy input transitions in 3.3 V digital systems. It is commonly deployed in oscillator circuits, debounce circuits for mechanical switches, and waveform shaping applications in embedded controllers and communication interfaces. The hex configuration allows six independent signal conditioning channels within a single compact SSOP package.

Frequently Asked Questions
What type of inverter is the SN74LV14ADB and why does it matter?
The SN74LV14ADB is a Schmitt-trigger inverter, which means it has built-in hysteresis on its input threshold. This makes it ideal for cleaning up slow-rising, slow-falling, or noisy digital signals by providing sharp output transitions, unlike standard inverters that can oscillate on borderline inputs.
What supply voltage range does the SN74LV14ADB support?
The SN74LV14ADB operates from a supply voltage of 2.7 V to 3.6 V, making it compatible with 3.3 V digital systems. It belongs to the LV (Low Voltage) logic family, designed for low-power portable and embedded applications that cannot tolerate 5 V TTL logic levels.
What package does the SN74LV14ADB come in?
The SN74LV14ADB is available in a 14-pin plastic surface-mount package designated JESD-30 R-PDSO-G14 (SSOP or SOIC style). The compact rectangular package is suitable for PCB designs with limited board space and is compatible with standard reflow soldering processes.
How many inverter channels does the SN74LV14ADB provide?
The SN74LV14ADB provides 6 independent inverting Schmitt-trigger channels, each with a single input pin. All six channels are fully independent and can be used simultaneously, allowing one IC to replace up to six discrete inverters or signal conditioners on a PCB.
What are common alternatives to the SN74LV14ADB?
Common alternatives include the SN74HC14 for 5 V CMOS systems, the SN74HCT14 for 5 V TTL-compatible inputs, or the SN74LV14APWR in TSSOP-14 package for different footprint requirements. For ultra-low voltage use, consider the SN74AUP1G14 single-gate version at 0.8 V to 3.6 V.
