74LS290 INTEGRATED CIRCUIT DIP-14 74LS290PC

The 74LS290 Integrated Circuit, specifically the 74LS290PC variant, is a decade counter/frequency divider packaged in a DIP-14 configuration. This versatile TTL (Transistor-Transistor Logic) device provides a convenient and cost-effective solution for counting and frequency division applications in digital electronic circuits. The 74LS290 is essentially a 4-bit binary counter consisting of four master-slave flip-flops internally connected to provide either a divide-by-two section and a divide-by-five section. These sections can be used independently or cascaded to achieve a divide-by-ten (decade) counter. The 74LS290PC offers asynchronous reset inputs (R0(1) and R0(2)) that allow the counter to be cleared to a zero state. It also features set-to-nine inputs (R9(1) and R9(2)) that force the counter to a count of nine.

These control inputs provide flexibility in implementing various counting sequences and control functions. The DIP-14 package facilitates easy insertion into breadboards and PCBs, making it suitable for prototyping, hobbyist projects, and production applications. The TTL logic family ensures compatibility with a wide range of other digital components. LSI keywords associated with this product include: decade counter, frequency divider, 74LS series, TTL logic, DIP package, binary counter, asynchronous reset, set-to-nine, digital counter, digital logic, electronic components, through-hole components, counter circuit, divider circuit, digital electronics, 4-bit counter. The 'LS' designation in the part number indicates that this is a low-power Schottky device, offering improved speed and reduced power consumption compared to earlier TTL families. This makes the 74LS290PC a relatively energy-efficient choice for a wide range of applications.

The 74LS290PC is commonly used in frequency synthesizers, digital clocks, event counters, and timer circuits. Its ability to be configured as either a divide-by-two, divide-by-five, or divide-by-ten counter makes it a flexible building block for various digital systems. Its robust design and wide operating voltage range (typically 4.75V to 5.25V) ensure reliable performance in demanding applications. Each unit is rigorously tested to ensure consistent performance and adherence to specified parameters. Build reliable counting and frequency division circuits with the 74LS290 Integrated Circuit. Its versatility, ease of use, and compatibility with other TTL devices make it an indispensable component for your digital electronics projects.
