SN74LV393ATPWRQ1

The SN74LV393ATPWRQ1 is a dual 4-bit binary ripple counter from Texas Instruments, designed for low-voltage applications. It is part of the LV (Low Voltage) family of logic devices, which are optimized for operation at lower supply voltages, typically ranging from 2.7V to 5.5V. This makes it suitable for battery-powered devices and other applications where power efficiency is critical.

Key Features:

1. Dual 4-Bit Counter: The device contains two independent 4-bit binary counters, allowing for counting operations in two separate channels. Each counter can count from 0 to 15 (in binary).

2. Ripple Counter Configuration: The counters operate in a ripple mode, meaning that the output of one counter can be used as the clock input for the next, allowing for cascading counting operations.

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

4. Low Power Consumption: The SN74LV393ATPWRQ1 is designed to consume minimal power, making it ideal for low-power applications. It has a low input and output leakage current, which contributes to its efficiency.

5. Wide Operating Temperature Range: The device is rated for operation over a wide temperature range, typically from -40°C to +125°C, making it suitable for automotive and industrial applications.

6. TTL Compatible: The outputs are compatible with TTL (Transistor-Transistor Logic) levels, ensuring that it can interface with a variety of other digital logic devices.

7. Package Type: The SN74LV393ATPWRQ1 is available in a TSSOP (Thin Shrink Small Outline Package) form factor, which is compact and suitable for space-constrained applications.

8. Pin Configuration: The device typically features pins for power supply (Vcc and GND), clock inputs, reset inputs, and output pins for each of the counters. The specific pin configuration can be found in the datasheet.

Applications:

• Frequency Division: The counters can be used in frequency division applications, where the output frequency needs to be reduced.
• Event Counting: Ideal for counting events in various applications, such as digital counters in consumer electronics.
• Timer Circuits: Can be used in timer circuits where precise timing is required.
• Digital Logic Circuits: Useful in various digital logic applications where counting is necessary.

Conclusion:

The SN74LV393ATPWRQ1 is a versatile and efficient dual 4-bit binary ripple counter that is well-suited for a range of low-voltage and low-power applications. Its features, such as asynchronous reset and TTL compatibility, make it a valuable component in digital design and embedded systems. For detailed specifications, including electrical characteristics and timing diagrams, referring to the official Texas Instruments datasheet is recommended.
