SN74HC14DR Hex Schmitt Trigger Inverter IC – SOIC-14 – Texas Instruments

The SN74HC14DR from Texas Instruments is a high-performance hex Schmitt-trigger inverter designed for reliable digital signal conditioning and logic processing. This device integrates six independent inverters, each with Schmitt-trigger input circuitry that delivers superior noise immunity and clean switching performance—even with slow or noisy input signals.

Operating from a 2V to 6V supply range, the SN74HC14DR is suitable for both low-voltage and standard CMOS logic systems. It features strong output drive capability of ±5.2mA and a typical 21 ns propagation delay at 6V, ensuring stable and responsive operation in a wide variety of embedded and digital applications.

Integrated clamp diodes provide input protection, while the device maintains reliable performance across –40°C to +85°C (industrial temperature range). Packaged in a compact SOIC-14 surface-mount form, it is widely used in waveform shaping, debouncing, signal cleaning, oscillator circuits, and general digital logic conditioning.
