• Digital counters
• Timers
• Address decoders
• Instrumentation
• Industrial control systems

Features

• Synchronous counting operation

• Synchronous parallel load input
• Cascadable
• High-speed operation
• TTL compatible
• Typical clock frequency of 25MHz

Benefits

• Provides accurate and reliable counting functions.
• Simplifies the design of digital systems requiring counting.
• Enables the creation of complex counters by cascading multiple devices.
• The synchronous clear and load inputs improve system timing control.
• High-speed operation allows use in various demanding applications.

Additional Details

The DM74160N operates on a 5V power supply. The counter advances on the positive transition of the clock input, provided that the enable inputs (ENT and ENP) are both high. The synchronous clear input, when low, resets the counter to zero on the next clock pulse. The synchronous parallel load input allows the counter to be preset to any desired value. The device is housed in a 16-pin DIP (Dual In-line Package).

The '160 is a decade counter, meaning it counts from 0 to 9 and then resets to 0. This makes it suitable for applications where decimal counting is required. Internal carry look-ahead circuitry enables cascading of multiple counters for higher counting ranges without significant performance degradation.
