ON Semiconductor 74AC163PC: Synchronous Presettable Binary Counter

The ON Semiconductor 74AC163PC is a high-speed, synchronous, presettable binary counter designed to provide advanced counting solutions for a wide array of digital applications. This integrated circuit is a member of the AC family, known for its improved speed performance over the standard logic families. The 74AC163PC is particularly suitable for operation in high-speed counting environments due to its robust construction and efficient design.

Constructed with an advanced CMOS technology, the 74AC163PC offers a synchronous reset feature that allows the counter to be quickly and accurately reset to a preset value. This is a crucial feature for systems that require precise timing and control, such as digital clocks, frequency dividers, and various sequencing functions.

The device has a 4-bit binary counter architecture, which allows it to count up to 16 different states, making it versatile for a range of counting tasks. Furthermore, the 74AC163PC can be preset to any binary value at any time during operation through its parallel load inputs, which adds to its flexibility in various applications.

The counter increments on the rising edge of the clock signal, ensuring that the counting operation is synchronized with other system components. It also features a look-ahead carry output, which facilitates easy cascading of multiple counters without incurring additional propagation delays that are typically associated with ripple-carry configurations.

Key features of the 74AC163PC include:

• High-speed synchronous counting
• Presettable to any binary value
• Look-ahead carry for easy expansion
• Output capability: Standard
• ICC category: Counter
