SN74LV393ADR

The SN74LV393ADR is a dual 4-bit binary ripple counter manufactured by Texas Instruments. It is designed for low-voltage applications and operates within a supply voltage range of 2V to 5.5V, making it suitable for modern digital circuits that require low power consumption.

Key Features:

1. Dual 4-Bit Counter: The device contains two independent 4-bit binary counters, allowing for versatile counting applications. Each counter can count from 0 to 15 (binary 0000 to 1111).

2. Ripple Counter Configuration: The SN74LV393 operates as a ripple counter, meaning that the output of one flip-flop serves as the clock input for the next flip-flop. This configuration allows for simple cascading of counters.

3. Asynchronous Reset: Each counter features an asynchronous reset function, which allows the counters to be reset to zero regardless of the clock state. This is useful for initializing the counter to a known state.

4. Count Enable: The device includes a count enable feature that allows the counters to be enabled or disabled based on external control signals. This feature is useful for controlling when counting occurs.

5. Output Logic Levels: The outputs of the counters are compatible with standard TTL logic levels, ensuring compatibility with a wide range of digital circuits.

6. Low Power Consumption: The SN74LV393 is designed for low power operation, making it ideal for battery-powered applications and energy-efficient designs.

7. Temperature Range: The device operates over a wide temperature range, typically from -40°C to +125°C, making it suitable for industrial and automotive applications.

8. Package Type: The SN74LV393ADR is available in a 16-pin TSSOP (Thin Shrink Small Outline Package) form factor, which is compact and suitable for space-constrained applications.

Applications:

• Digital counting applications
• Frequency division
• Event counting
• Timer circuits
• Frequency counters
• Digital clocks

Electrical Characteristics:

• Supply Voltage (Vcc): 2V to 5.5V
• Input Voltage Levels: Recognizes standard logic levels for high and low states.
• Propagation Delay: The time it takes for a change at the input to affect the output, typically in the nanosecond range, depending on the supply voltage and load conditions.

Conclusion:

The SN74LV393ADR is a versatile and efficient dual 4-bit binary counter that is well-suited for a variety of digital counting applications. Its low power consumption, wide operating voltage range, and robust features make it a popular choice among engineers and designers in the field of digital electronics.
