The CD54HC163F is a synchronous presettable 4-bit binary counter belonging to the high-speed CMOS logic family (HC). Designed for applications requiring high-speed counting and frequency division, it offers synchronous counting and clearing operations. The '54' prefix indicates that this part is designed for operation over the military temperature range (-55°C to +125°C) and meets specific military standards for reliability and performance. The 'F' suffix denotes a specific package type.

Applications:

• Frequency Dividers: Used to divide the frequency of a clock signal in digital circuits.
• Digital Timers: Forms the core of digital timing circuits in various electronic systems.
• Counters: Implements counting functions in industrial control systems, instrumentation, and other digital applications.
• Address Generation: Used in memory addressing schemes for data storage and retrieval.
• Sequence Generators: Generates digital sequences for control and testing purposes.

Features:

• Synchronous Counting: All flip-flops are clocked simultaneously, ensuring accurate and predictable counting.
• Synchronous Clearing: The counter can be cleared synchronously with the clock signal.
• Synchronous Presetting: The counter can be preset to any desired value synchronously with the clock signal.
• Carry Output: Provides a carry output signal for cascading multiple counters to achieve higher counting ranges.
• High-Speed Operation: Operates at high clock frequencies due to the CMOS technology.

Benefits:

• Accurate Counting: Synchronous operation ensures accurate and reliable counting in digital systems.
• Versatile Functionality: Supports clearing and presetting operations for flexible counting applications.
• High-Speed Performance: Enables high-speed counting and frequency division in demanding applications.
• Cascadable Design: Can be easily cascaded with other counters to achieve higher counting ranges.

Additional Details: The CD54HC163F operates with a supply voltage (VCC) typically between 2V and 6V. The maximum clock frequency is dependent on the supply voltage. The device features a carry output that allows cascading multiple '163' counters to create counters of arbitrary lengths. The synchronous clear input overrides all other inputs. The 'F' suffix likely indicates a flatpack or other specialized package for military applications. The device also offers enable inputs (ENP and ENT) which must be asserted to enable the counting function. All inputs are protected against static discharge.
