DM7490AN INTEGRATED CIRCUIT DIP-14

The DM7490AN is a versatile decade counter integrated circuit, housed in a 14-pin Dual In-Line Package (DIP-14). This IC is a fundamental building block in digital logic circuits, widely used for counting, frequency division, and timing applications. The DIP-14 package is a through-hole mounting style, making it easy to prototype and integrate into various circuit designs. The DM7490AN functions as a modulo-10 counter, meaning it counts from 0 to 9 and then resets to 0. It consists of four master-slave flip-flops, internally connected to provide either a divide-by-2 counter or a divide-by-5 counter. By connecting the outputs of these counters, it can be configured as a decade counter.

The DM7490AN features two independent clock inputs, allowing for flexible counting configurations. One clock input triggers the divide-by-2 counter, while the other triggers the divide-by-5 counter. By cascading these counters, it can achieve a decade counting function. The DM7490AN also includes reset inputs, which allow the counter to be reset to a specific state. These reset inputs can be used to synchronize the counter with other circuits or to implement specific counting sequences. The DM7490AN is designed to operate with a wide range of supply voltages, typically from 4.5V to 5.5V, making it compatible with various logic families.

Its low power consumption makes it suitable for battery-powered applications. The DM7490AN is commonly used in digital clocks, frequency counters, and other counting circuits. Its versatility and ease of use make it an excellent choice for these applications. When using the DM7490AN, it is important to consider its timing characteristics. The maximum clock frequency is typically around 25 MHz, and the propagation delay is typically around 25 ns. These parameters should be considered when designing circuits that use the DM7490AN.

The DM7490AN is a versatile and reliable integrated circuit that can be used in a wide range of digital logic applications. Whether you're designing a digital clock, a frequency counter, or a custom counting circuit, the DM7490AN provides a high-performance and cost-effective solution. Its flexible counting configurations, reset inputs, and low power consumption make it a valuable component for any electronics engineer.
