SN7490AN INTEGRATED CIRCUIT DIP-14

The SN7490AN is a decade counter integrated circuit, designed for frequency division, timing, and counting applications. Housed in a 14-pin Dual In-line Package (DIP-14), this IC provides a convenient and reliable solution for generating digital pulses and counting events in various electronic systems. The SN7490AN is a monolithic BCD decade 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 a divide-by-2 section and a divide-by-5 section. These sections can be used independently or cascaded to achieve a divide-by-10 counter. The SN7490AN features two reset inputs (R0(1) and R0(2)) that, when both are high, reset the counter to zero.

It also has two set-to-nine inputs (R9(1) and R9(2)) that, when both are high, set the counter to nine. These reset and set inputs provide flexible control over the counter's operation. Operating from a wide supply voltage range, typically between 4.5V and 5.5V, the SN7490AN is suitable for various digital systems. Its low power consumption contributes to energy efficiency, making it a preferred choice for battery-powered devices and systems with limited power budgets. The fast counting speed of the SN7490AN enables it to handle high-frequency signals with minimal distortion. The DIP-14 package simplifies prototyping and breadboarding, making it easy to integrate into existing circuits.

Its robust design ensures reliable operation in harsh environments. Typical applications include frequency dividers, digital clocks, event counters, and timing circuits. The SN7490AN is a versatile and reliable integrated circuit that provides a cost-effective solution for counting and frequency division. Whether you're working on digital timers, frequency synthesizers, or industrial control systems, the SN7490AN offers the performance and flexibility you need. Upgrade your project with the SN7490AN and experience seamless counting and timing control. Don't miss out on this essential component for your electronic projects.
