SN74LV393AD

Counter Dividers Overview

The SN74LV393AD is a dual 4-bit binary counter from the Texas Instruments 74LV series, housed in a 14-SOIC surface-mount package. It features two independent counters with negative-edge triggering and asynchronous reset capabilities. The device operates within a supply voltage range of 2 V to 5.5 V and supports a counting rate up to 70 MHz. It functions reliably across an extended temperature range of -40°C to +85°C.

Counter Dividers Feature Summary

• Dual independent 4-bit binary counting architecture
• Negative-edge triggered clock input for precise timing control
• Asynchronous reset functionality for immediate state clearing
• Wide operating voltage compatibility supporting low-power systems

Counter Dividers Applications

• Digital frequency division circuits
• Event counting and measurement systems
• Timing sequence generation logic
• Address decoding in memory interfaces

Counter Dividers Procurement Notes

Verify the specific suffix 'AD' corresponds to the 14-SOIC narrow package variant when sourcing. Confirm RoHS3 compliance status as manufacturing processes may evolve. Ensure the supplier provides official datasheets matching the SN74LV393A family specifications to guarantee functional equivalence. Check for any recent Product Change Notifications regarding material or assembly updates.

Counter Dividers Selection Notes

Select this component when a compact dual-counter solution is required for space-constrained designs. The 74LV series offers superior speed compared to standard 74LS counterparts while maintaining CMOS power efficiency. Consider the 14-SOIC package for automated surface-mount assembly processes. Verify that the 70 MHz maximum frequency meets the system's clock requirements.

Counter Dividers Part Context

This part belongs to the Texas Instruments 74LV (Low Voltage) logic family, designed for high-speed digital applications. It serves as a successor to older bipolar logic families, offering improved performance metrics. The SN74LV393A designation indicates the enhanced version of the base 74LV393 specification, ensuring robust operation across varying industrial conditions.

Counter Dividers Replacement Considerations
