SN74HC193QPWRQ1

Counter Dividers Overview

The SN74HC193QPWRQ1 is an automotive-grade, 4-bit synchronous up/down binary counter from Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports asynchronous loading. The device features dual clock inputs for independent up and down counting operations, along with a dedicated clear input. It is qualified under AEC-Q100 standards for automotive applications and functions reliably across an extended temperature range of -40°C to +125°C.

Counter Dividers Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• Synchronous 4-bit bidirectional counting capability
• Asynchronous parallel data loading mechanism
• Independent up and down clock inputs

Counter Dividers Applications

• Automotive electronic control units requiring precise timing sequences
• Vehicle instrumentation systems utilizing digital counters
• Industrial automation controllers operating in harsh environments

Counter Dividers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free packaging compliance when sourcing. Confirm that the 'Q1' designation strictly denotes automotive grade qualification. Ensure the TSSOP-16 package matches the target PCB footprint requirements. Cross-reference the manufacturer datasheet for any recent pinout or electrical specification updates prior to final procurement.

Counter Dividers Selection Notes

Select this component for designs requiring robust automotive reliability and synchronous counting logic. It is suitable for applications needing independent up/down control without external decoding logic. Consider the HC series speed and power characteristics against system requirements. Verify compatibility with existing voltage levels and thermal management strategies for the intended operating environment.

Counter Dividers Part Context

This part belongs to the SN74HC193 family of 4-bit synchronous up/down counters. The Q1 suffix identifies it as an automotive-grade variant manufactured by Texas Instruments. It shares functional similarities with standard commercial counterparts but meets stricter automotive quality and reliability standards. The G4 suffix typically denotes lead-free and RoHS-compliant packaging materials.

Counter Dividers Replacement Considerations

SN74HC193NSR is a commercial-grade alternative with similar functionality but lacks automotive qualification. SN74HC193QPWRG4Q1 is a direct equivalent with identical specifications and automotive grading.
