The 74HCT393N is a high-speed Si-gate CMOS device that is part of the 74HCT family of integrated circuits, designed and manufactured by NXP Semiconductors. This product is known for its robust performance and compatibility with TTL (Transistor-Transistor Logic) levels.
Key Features
- Logic Type: Dual 4-bit binary ripple counter
- Supply Voltage Range: 4.5V to 5.5V, optimized for 5V systems
- High-Speed Performance: Typical clock frequency of 30 MHz
- Output Capability: Standard outputs with 5.2 mA output drive capability at 5V
- Compatibility: TTL input level threshold for seamless integration with older logic families
- Package: DIP-14 (Dual In-line Package with 14 pins)
Product Description
The 74HCT393N comprises two 4-bit binary ripple counters with individual clock inputs (nCP0 and nCP1) but shared master reset inputs. Each counter features a divide-by-two section and a divide-by-eight section, which can be used separately or combined to function as a divide-by-16 binary counter.
Featuring a fully static operation, the counters advance on the falling edge of the clock pulse, allowing for precise timing and control in a variety of applications. The master reset input overrides all other inputs and clears the counter to its zero state when a high level is applied.
With its wide operating temperature range and the ability to interface directly with TTL systems, the 74HCT393N is suitable for use in functions such as frequency division, time delay generation, and event counting in industrial control systems, consumer electronics, and data processing equipment.
Applications
- Industrial controls
- Consumer electronics
- Data processing
- Instrumentation
- Time delay generation
As a testament to NXP's commitment to quality, the 74HCT393N is rigorously tested to ensure reliability and performance, making it a preferred choice for designers and engineers seeking a dependable counter solution.
