SN74LV393ATPWRQ1

Counter Dividers Overview

The SN74LV393ATPWRQ1 is an automotive-grade dual 4-bit binary counter from Texas Instruments, designed for high-speed digital applications. It operates within a supply voltage range of 2 V to 5.5 V and features a maximum propagation delay of 9.5 ns at 5 V. The device utilizes negative-edge triggering and includes independent clock inputs for each counter section. Packaged in a 14-TSSOP format, it meets AEC-Q100 qualification standards for automotive electronics, ensuring reliability across a temperature range of -40°C to +105°C.

Counter Dividers Feature Summary

• Dual independent 4-bit binary up-counter architecture with separate clock inputs
• Negative-edge triggered operation for precise timing control
• Automotive qualification compliant with AEC-Q100 standards
• Wide operating voltage range supporting 2 V to 5.5 V systems

Counter Dividers Applications

• Automotive electronic control units requiring frequency division
• Digital timing circuits in vehicle infotainment systems
• Counter logic in automotive sensor interface modules
• Binary counting applications in automotive body control networks

Counter Dividers Procurement Notes

Verify the complete part number including suffixes such as G4 or Q1 when ordering, as these may indicate specific tape-and-reel configurations or packaging variations. Confirm that the supplier provides documentation proving AEC-Q100 compliance for automotive deployment. Ensure the procurement channel sources genuine Texas Instruments components to avoid counterfeit risks associated with automotive-grade logic ICs.

Counter Dividers Selection Notes

Select this component when designing automotive systems requiring dual independent counters with low power consumption and wide voltage tolerance. The LV series technology offers improved switching speeds compared to standard LS counterparts while maintaining CMOS compatibility. Consider the TSSOP-14 package constraints for PCB layout if space is limited in dense automotive assemblies.

Counter Dividers Part Context

This device belongs to the SN74LVxAxQ1 family of automotive-qualified logic devices. It shares functional similarities with other LV series counters but is specifically optimized for automotive environments. The part integrates two distinct 4-bit counters into a single package, reducing board space compared to using discrete single counters.

Counter Dividers Replacement Considerations

Direct substitutes include the SN74LV393ATPWRG4Q1, which denotes the same functional device with potential packaging or reel specification differences. Verify pinout compatibility before replacing existing designs.
