The NXP 74HC163T is a high-speed Si-gate CMOS device and is pin compatible with low-power Schottky TTL (LSTTL). It is a 4-bit synchronous binary counter with a clock input (CP), an overriding asynchronous master reset input (MR), two synchronous load inputs (A and B), and a maximum/minimum count enable input (CEP and CET) for cascading counters. This integrated circuit is designed for use in high-performance counting applications.
Key Features:
- High-Speed Performance: The 74HC163T operates at high speeds with a typical clock frequency of 48 MHz, making it suitable for fast systems and high-speed counting operations.
- Synchronous Counting: All internal state changes, including the setting or resetting of outputs, are initiated by the rising edge of the clock pulse, ensuring precise control and timing of counting operations.
- Asynchronous Master Reset: The MR input allows the counter to be reset to zero immediately, regardless of the clock input, ensuring the counter can be quickly initialized as needed.
- Cascadable: The CEP (count enable parallel) and CET (count enable trickle) inputs enable multiple 74HC163T counters to be cascaded, allowing for the creation of larger counting systems without the need for additional decoding or control logic.
- Output Capability: Standard outputs are available for interfacing with other logic families, providing versatility in system design.
- Power and Temperature Ranges: This device can operate over a wide power supply range (2V to 6V) and temperature range (-40°C to +125°C), making it suitable for various operating environments.
Applications:
The NXP 74HC163T is ideal for a variety of applications that require precise counting, such as:
- Industrial control systems
- Frequency dividers
- Timers
- Programmable counters
- Interface counters
With its robust feature set and NXP's reputation for quality, the 74HC163T is a reliable choice for designers looking to incorporate a dependable counting solution into their digital systems.
