M74HCT14B1R

Inverter Gates Overview

The M74HCT14B1R is a high-speed CMOS hex Schmitt inverter manufactured by STMicroelectronics using silicon gate C2MOS technology. It features six independent inverters with Schmitt trigger inputs, providing hysteresis to filter noisy signals. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature from -55°C to 125°C. Key electrical characteristics include a typical propagation delay of 19ns at 4.5V, a maximum quiescent current of 1µA, and symmetrical output impedance. It is pin-compatible with the standard 74 series 14 logic family.
