The HD74LV393ATELL is a dual 4-bit binary counter manufactured by Renesas Electronics America. This device consists of two independent 4-bit binary counters, each with a separate clock and reset input. The outputs change state on the positive-going transition of the clock input. It is commonly used in applications requiring frequency division, counting, and timing control.

Applications

• Frequency dividers: Dividing input frequencies by powers of two.
• Timers and counters: Implementing timing and counting functions in digital systems.
• Address decoders: Generating address signals for memory and peripheral devices.
• Sequence generators: Creating specific timing sequences for control applications.
• Digital clocks: Used in digital clock circuits for counting seconds, minutes, and hours.

Features

• Dual 4-bit counters: Contains two independent 4-bit binary counters.
• Separate clock and reset inputs: Each counter has its own clock and reset input.
• Positive-edge triggered: Outputs change on the positive-going transition of the clock.
• Low voltage operation: Operates from 2 V to 5.5 V.
• Low power consumption: Minimizes energy usage.
• Wide operating temperature range: Functions effectively across a broad temperature range.

Benefits

• Versatile counting capabilities: Suitable for a wide range of counting and frequency division applications.
• Simplified circuit design: Easy to integrate into existing digital logic circuits.
• Energy efficiency: Low power consumption reduces energy costs and extends battery life in portable devices.
• Reliable operation: Wide operating temperature range ensures stable performance in various environments.
• Flexible control: Separate clock and reset inputs provide independent control over each counter.
• Cost-effective: Provides a cost-efficient solution for implementing binary counting functions.

Additional Details

The HD74LV393ATELL features asynchronous reset inputs, allowing for immediate clearing of the counter regardless of the clock signal. The maximum clock frequency typically ranges from 50 MHz to 100 MHz depending on the supply voltage. It is available in a variety of packages, including TSSOP (Thin Shrink Small Outline Package) and SOIC (Small Outline Integrated Circuit). This device is designed to be compatible with standard TTL and CMOS logic levels, ensuring easy integration with other digital components. The device's outputs can drive up to 10 LSTTL loads, making it suitable for interfacing with other digital devices.
