hd74ls90p datasheet

The HD74LS90P is a high-speed, synchronous, decade counter IC with asynchronous clear feature. It has a wide operating voltage range and can operate at higher frequencies, making it suitable for use in various applications such as frequency dividers, event counters, and general counting sequences. The HD74LS90P has a fully synchronous design, with all internal registers, including the counter and the flip-flops, being clocked simultaneously. This ensures precise and accurate counting without any risk of data corruption. Additionally, the IC features an asynchronous clear input, which allows the counter to be reset at any time, further enhancing its flexibility and usability. With its robust design and high-speed operation, the HD74LS90P is an ideal choice for designs that require accurate and reliable counting. It is available in a small, space-saving 14-pin package, making it ideal for use in compact designs where board space is limited.
