The 74HC266 is a high-speed CMOS hex Schmitt-trigger buffer designed for reliable digital signal processing. It contains six independent Schmitt-trigger inputs that provide enhanced noise immunity and stable switching characteristics for applications with slow or noisy input transitions.
Operating voltage: 2 V to 6 V for compatibility with diverse logic levels.
High noise immunity: Schmitt-trigger inputs reduce false triggering and improve signal integrity.
Output drive capability: ±6 mA to support multiple loads without additional buffering.
Propagation delay: Typically around 10 ns for fast timing performance.
Low power consumption: Approximately 20 µA per gate, suitable for battery-powered designs.
Compared with earlier logic families, the 74HC266 delivers superior speed and noise resistance while consuming less power. Its broad operating voltage range allows easy integration into both 3.3 V and 5 V systems without sacrificing performance. The Schmitt-trigger inputs provide improved signal conditioning over standard buffers, making this device a preferred choice where stable logic level transitions and immunity to electrical noise are required.
Use the 74HC266 when you need clean, reliable digital buffering with low power draw and consistent timing performance.
