Product Description
The 74HC393DR is designed for use in high-performance, high-speed counting applications. Each counter features a master reset input that resets the counter to its zero state. When the master reset is high, counting is disabled, allowing the user to control the operation of the counter precisely. The outputs change state on the falling edge of the clock pulse, ensuring synchronized output transitions.
Due to its wide operating voltage range and low power consumption, the 74HC393DR is suitable for battery-operated devices. Its fast propagation delay and high noise immunity are characteristics of the HC family, making it a robust choice for digital systems.
The device is provided in a small-outline 14-pin package, which is ideal for space-constrained applications. The surface-mount package allows for efficient assembly in high-volume production, and its robustness ensures long-term reliability.
Whether you're designing consumer electronics, industrial control systems, or complex computing hardware, the NXP 74HC393DR offers a reliable and efficient solution for your binary counting needs.
