74HC393 Dual 4 bit Binary Ripple Counter IC (74393) DIP 14 Package

74HC393 Dual 4 bit Binary Ripple Counter IC (74393) DIP 14 Package

The 74HC393 (commonly known as 74393) is a high-speed CMOS Dual 4-Bit Binary Ripple Counter IC. It consists of two independent 4-bit binary counters, each with a clock input (CP) and a master reset (MR). The device is designed for counting, frequency division, timing, and sequencing applications in digital logic systems.

Each counter within the 74HC393 divides the input frequency by 2, 4, 8, and 16 at successive output stages, making it suitable for frequency division and binary counting operations. The asynchronous master reset (MR) clears all outputs to LOW, ensuring predictable startup conditions.

Built on advanced CMOS technology, this IC offers high noise immunity, low power consumption, and high-speed operation, while maintaining TTL compatibility for seamless interfacing with other logic devices.
