74HC/LS192 2–6V Up/Down BCD Counter IC | Presettable, High-Speed, Low Power, DIP/SOP Package | Xinbole

The 74HC/LS192 is a high-performance synchronous up/down BCD counter IC designed for precise counting and control in digital systems. Built using advanced High-Speed CMOS (HC) and Low-Power Schottky TTL (LS) technologies, it ensures fast switching performance, low power consumption, and high noise immunity, making it ideal for modern embedded and industrial applications.

The LS variant utilizes Schottky transistor technology to reduce propagation delay and enhance switching speed, while the HC version offers ultra-low quiescent current and a wide operating voltage range from 2V to 6V. This provides a clear advantage over traditional TTL-only counters, enabling improved energy efficiency and seamless integration into mixed-voltage logic systems.

Featuring synchronous up/down counting with separate clock inputs, the 74HC/LS192 ensures accurate and glitch-free operation. Its presettable parallel load capability allows flexible initialization of count values, making it suitable for complex counting sequences and programmable systems. The optimized internal architecture supports stable thermal performance and long-term reliability under continuous operation.

Available in both DIP and SOP package types, the device offers flexibility for prototyping, PCB layout optimization, and compact production designs.
