The AM25LS163PC is a synchronous 4-bit binary counter from AMD. It is part of the low-power Schottky (LS) family of integrated circuits, offering a balance between speed and power consumption. This counter is designed for applications requiring accurate and reliable counting operations.
Applications
- Frequency dividers
- Address counters for memory systems
- Timing circuits
- Sequential control systems
- Digital clocks and timers
Features
- Synchronous counting operation: All flip-flops are clocked simultaneously, ensuring accurate counting.
- 4-bit binary counter: Counts from 0 to 15 (0000 to 1111 in binary).
- Low-power Schottky (LS) technology: Provides low power consumption and good speed.
- Asynchronous clear input: Allows for immediate reset of the counter.
- Carry output: Facilitates cascading multiple counters for higher-order counting.
- Enable inputs: Control the counting operation.
Benefits
- Accurate and reliable counting: Synchronous operation ensures precise counting.
- Low power consumption: Suitable for battery-powered and energy-sensitive applications.
- Easy to cascade: Carry output simplifies the design of larger counters.
- Versatile: Can be used in a wide range of counting and timing applications.
- Cost-effective: Widely available and relatively inexpensive.
Additional Details
The AM25LS163PC operates on a 5V power supply. The 'PC' suffix typically indicates a plastic DIP (Dual In-line Package). Key specifications include a maximum clock frequency, propagation delay, and power dissipation. The asynchronous clear input overrides all other inputs, immediately resetting the counter to zero. The enable inputs (Enable P and Enable T) must be active to allow the counter to increment on each clock pulse. The carry output goes high when the counter reaches its maximum count (15) and both Enable P and Enable T are high, enabling cascading with other counters. It is important to consult the datasheet for specific timing parameters and operating conditions.
