The 74HC/LS90 from Xinbole is a high-performance decade counter and frequency divider logic IC designed for precise counting and timing applications in modern digital electronic systems. Operating over a wide supply voltage range from 2V to 6V, this device is available in both high-speed CMOS (74HC) and low-power Schottky TTL (74LS) compatible versions, making it suitable for industrial control, instrumentation, computing, and embedded digital designs.
Built using advanced sequential logic and counter technology, the 74HC/LS90 provides divide-by-2 and divide-by-5 counter sections, enabling flexible frequency division and decimal counting operations. The 74HC version ensures ultra-low power consumption with CMOS efficiency, while the 74LS version uses Schottky TTL architecture for faster switching performance and reduced propagation delay. This ensures accurate counting, stable timing, and reliable pulse processing in digital systems.
Compared to lower-series counter ICs, the 74HC/LS90 delivers improved speed performance, better energy efficiency, and wider voltage compatibility, making it suitable for both modern low-power systems and legacy TTL-based designs. Its robust internal architecture ensures stable operation even in electrically noisy environments, improving overall system reliability and counting accuracy.
Available in both DIP and SOP package options, the 74HC/LS90 supports flexible PCB integration for prototyping and mass production. It is widely used in digital counters, frequency dividers, clocks, timers, industrial instrumentation, and embedded electronics. With its combination of precision, efficiency, and reliability, the Xinbole 74HC/LS90 is a dependable solution for digital counting applications.
