Product Overview: 74HCT160D
The 74HCT160D is a high-speed Si-gate CMOS device manufactured by NXP Semiconductors. It is a synchronous presettable binary counter that features an internal look-ahead carry for cascading purposes in high-speed counting applications. This integrated circuit is part of the 74HCT family, which is known for its compatibility with TTL (Transistor-Transistor Logic) levels, allowing it to be used in systems incorporating both CMOS and TTL technologies.
Key Features
- Synchronous Counting and Loading: The counter operation is synchronized by the clock input (CP), ensuring precise timing for all counting and loading operations.
- High-Speed Performance: The 74HCT160D is designed to operate at high speeds, with a typical clock frequency of tens of MHz, making it suitable for high-speed applications.
- Look-Ahead Carry Output: This feature provides a carry output (Cn+4) for n-bit cascaded counters, without additional gating, ensuring efficient counting for multiple cascaded units.
- Reset Function: The master reset (MR) input allows the counter to be set to its zero state asynchronously, which is essential for initializing the count at the start of an operation.
- Presettable Count: The parallel load input (PL) enables the counter to be preset to any desired value when the parallel load input is LOW.
- Output Capability: Standard outputs are available, which can drive up to 10 LSTTL loads, providing versatility in interfacing with other logic families.
- Power Supply: The device can be powered by a wide range of voltages from 4.5V to 5.5V, allowing for flexibility in various system designs.
