74HC193 (Presettable Synchronous Counter)

Overview

The 74HC193 is a high-speed, presettable synchronous 4-bit binary up/down counter from the 74HC family. It is designed for a wide range of digital counting applications, offering both up and down counting modes with synchronous operation. This IC is ideal for projects that require precise counting, frequency division, or event sequencing, making it a staple in digital electronics, robotics, and embedded systems.

Key Features

• Synchronous Operation: All flip-flops are clocked simultaneously, reducing propagation delays and ensuring reliable counting.
• Presettable: Four parallel data inputs (P0-P3) allow you to load a specific count value, giving you full control over the starting point.
• Up/Down Counting: Direction is controlled by separate up and down clock inputs (CPU and CPD).
• High-Speed: Propagation delay as low as 37 ns at 6V supply, enabling fast counting in high-frequency applications.
• Wide Supply Voltage Range: Operates from 2V to 6V, making it compatible with both 3.3V and 5V logic systems.
• Carry and Borrow Outputs: Provide cascading capability for multi-stage counters without additional logic.
• Wide Operating Temperature: Works reliably from -40°C to +125°C, suitable for industrial environments.
