The M74HC190RM13TR is part of the 74HC logic family and is a 4-bit asynchronous reversible binary counter, which means that its outputs can be used to load data. This device is available in the SOIC-14 package and the lead finish Reel E3.

The M74HC190RM13TR is well suited for use in high-speed high-density applications, as it can count up or down from 0 to 15 with no additional logic. This makes it ideal for various applications such as in time division multiplexers, frequency dividers, frequency counters, traffic control systems, motor speed measurement and control, security systems and various data acquisition applications.

The M74HC190RM13TR can operate at up to 24 MHz with a power supply voltage range of 2.0 to 6.0 volts. The counter can count in either direction, forward or backward, and has two inputs, which can be used to either reset or clock the counter. The most commonly used input is the clock input, which causes the counter to increment or decrement on the rising edge of the clock. It also has an asynchronous reset input, which can be used to either reset the counter to zero or a predetermined count, depending on the application.

The M74HC190RM13TR also allows for cascading of multiple counters. This is done by connecting the carry out and carry in pins, which allows for each successive counter to count up or down as the previous counter reaches its highest or lowest count. This cascading feature makes it possible to create an almost limitless number of counting functions.

The M74HC190RM13TR is an ideal device for those requiring an asynchronous 4-bit reversible binary counter which can count in both directions at high speeds. This device is relatively inexpensive, making it ideal for use in various applications, such as in time division multiplexers, frequency dividers, frequency counters, traffic control systems, motor speed measurement and control, security systems, and various data acquisition applications.
