STMicroelectronics M74HC393B1 Dual Binary Counter

The M74HC393B1 is a high-speed CMOS Dual 4-Bit Binary Ripple Counter integrated circuit, manufactured by the renowned semiconductor company, STMicroelectronics. Designed to operate with a power supply range of 2V to 6V, this device offers the perfect blend of power efficiency and performance, making it suitable for a wide array of electronic applications.

This versatile counter consists of two independent 4-bit binary counters, each having a clear input (nCLR) and a clock input (nCP). The counters are designed to increment on the falling edge (negative transition) of the clock input signal, providing a reliable and predictable counting sequence for precision applications. The clear input allows for the synchronous reset of the counter to zero when it is set to a high level.

One of the key features of the M74HC393B1 is its ability to be cascaded in both the ripple and synchronous configuration. This means that multiple devices can be connected to achieve higher count lengths and more complex counting arrangements without significant complexity or power consumption increases.

The M74HC393B1 is built using silicon gate CMOS technology, which ensures low power dissipation, high noise immunity, and a robust protection against static discharge. This makes the device suitable for use in digital systems where low power and reliability are critical, such as timers, frequency dividers, and state machines in consumer electronics, automotive applications, and industrial control systems.

STMicroelectronics packages the M74HC393B1 in a 14-pin plastic DIP (Dual In-line Package) for through-hole mounting, which facilitates easy integration into a variety of circuit boards. The device is also characterized for operation from -55°C to 125°C, ensuring that it can perform reliably in extreme temperature conditions.

With its high functionality and STMicroelectronics' reputation for quality, the M74HC393B1 is a go-to choice for designers looking for a dependable and efficient binary counter solution.
