CLVC244AQPWRG4Q1

Overview

The CLVC244AQPWRG4Q1 is an automotive-grade octal buffer and line driver from Texas Instruments, belonging to the LVC logic series. It features eight non-inverting inputs and outputs housed in a TSSOP-20 package. The device operates within a supply voltage range of 1.65 V to 3.6 V. It provides high drive capability with output currents of -24 mA at high level and 24 mA at low level. Propagation delays are specified as 6.7 ns at 2.7 V and 5.7 ns at 3.3 V. The component is qualified under AEC-Q100 standards and supports a wide operating temperature range from -40°C to +125°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
• Octal configuration providing eight independent non-inverting buffer channels in a single package.
• Low-voltage operation capability supporting systems powered between 1.65 V and 3.6 V.
• High-output drive strength enabling effective signal buffering for demanding loads.

Applications

• Automotive electronic control units requiring robust signal buffering.
• Infotainment system interfaces utilizing low-voltage logic levels.
• Body control modules needing high-density octal buffering solutions.
• Telematics units operating in extended temperature automotive environments.

Procurement Notes

Verify the complete part number including suffixes to ensure correct automotive qualification and packaging type. Confirm that the specific revision matches your design requirements for voltage and temperature ranges. Check official Texas Instruments documentation for the latest RoHS compliance status and lead time information before finalizing procurement decisions.

Selection Notes

Select this component when designing for automotive applications requiring low-voltage operation and high drive current. The LVC series offers a balance of speed and power consumption suitable for modern vehicle electronics. Ensure the TSSOP-20 package fits your PCB layout constraints. Compare propagation delay specifications against your system timing requirements at the intended operating voltage.

Part Context

This device is part of the SN74LVC244A family of octal buffers and drivers. It shares functional similarities with other automotive-qualified logic ICs but is distinguished by its specific LVC technology and low-voltage characteristics. The Q1 suffix indicates automotive grade qualification, differentiating it from standard commercial variants.

Replacement Considerations

Direct substitutes include other automotive-qualified octal buffers from the same manufacturer, such as the SN74LVC244AQPRQ1 or SN74LVC244AQPWRQ1. Verify pin compatibility and electrical specifications before substitution. Cross-referencing with similar parts from other vendors requires careful validation of voltage ranges and drive capabilities.
