HD74LS192, Synchronous Up,Down Decade Counter, DIP-16

The HD74LS192 is a synchronous up/down decade counter, designed for binary counting applications requiring directional control and preset functionality. With independent clock inputs for up and down counting, this counter provides precise control over counting direction and timing. Operating between 4.75V and 5.25V, the HD74LS192 is ideal for TTL-based digital systems. It features an asynchronous master reset to clear the counter instantly and an asynchronous parallel load to preset values directly. Supporting clock speeds up to 25 MHz, this counter is ideal for high-speed frequency division, timing circuits, and digital sequencing applications. Its DIP-16 package allows for easy integration into standard PCB designs.

• Synchronous 4-Bit Up/Down Counter – Capable of binary counting in both directions, with dual clock lines for flexibility.
• Wide Voltage Range – Operates between 4.75V to 5.25V, ensuring stability in TTL logic circuits​
• High-Speed Operation – Supports a maximum count rate of 25 MHz, making it suitable for high-frequency applications​HD74LS192 (1).
• Asynchronous Parallel Load – Allows preset values to be loaded instantly, independent of the clock signal.
• Asynchronous Clear Function – Ensures immediate reset, overriding all other inputs when required.
• Standard DIP-16 Package – Through-hole DIP package for easy PCB mounting and prototyping.
