74HC/LS193 2–6V Up/Down Binary Counter IC | 4-Bit Synchronous, High-Speed, DIP/SOP Package | Xinbole

The 74HC/LS193 is a high-performance 4-bit synchronous up/down binary counter IC designed for precise counting and control in advanced digital systems. Built using High-Speed CMOS (HC) and Low-Power Schottky TTL (LS) technologies, it delivers fast switching speeds, low power consumption, and excellent noise immunity, ensuring stable and reliable performance in modern electronic applications.

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

Featuring synchronous up/down counting with separate clock inputs, the 74HC/LS193 ensures accurate and glitch-free operation. It includes parallel load and reset capabilities, allowing flexible control for programmable counting sequences and system initialization. Its optimized internal architecture ensures efficient thermal performance and long-term reliability, even in continuous industrial operation.

Available in both DIP and SOP package types, the device supports easy prototyping and compact PCB integration for high-density electronic designs.
