74LVC244APW-Q100J

Overview

The Nexperia 74LVC244APW-Q100J is an octal non-inverting buffer and line driver featuring three-state outputs, housed in a TSSOP20 (SOT360-1) package. It operates within a supply voltage range of 1.2 V to 3.6 V and supports input voltages up to 5.5 V for interfacing with 5 V logic devices. The component meets AEC-Q100 Grade 1 qualification standards for automotive applications, ensuring reliability across operating temperatures from -40 °C to +125 °C.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 Grade 1 standards
• Three-state outputs controlled by dedicated active-low enable inputs
• Schmitt-trigger action at all inputs for tolerance against slow signal transitions
• High-impedance OFF-state maintained when the supply voltage is zero

Applications

• Interfacing between 3.3 V and 5.0 V logic systems
• Car electronics requiring robust signal buffering
• Data acquisition systems utilizing mixed-voltage environments

Procurement Notes

Verify the specific suffix 'PW' confirms the TSSOP20 package variant during procurement. Confirm that the Q100 designation aligns with required automotive grade specifications. Ensure the ordering information matches the exact temperature range requirements for the target application environment.

Selection Notes

Select this component when an octal buffer with three-state control is required for automotive or industrial designs. It is suitable for applications needing direct interface with TTL levels and wide supply voltage flexibility. Consider the TSSOP20 package dimensions if space constraints are present on the printed circuit board layout.

Part Context

This device belongs to the Nexperia 74LVC244A-Q100 family of octal buffers. It shares functional similarities with other members like the 74LVCH244AD-Q100 but differs in packaging and specific electrical characteristics. The product line emphasizes low power consumption and high noise immunity for modern electronic systems.

Replacement Considerations

Direct replacements include the 74LVC244AD-Q100J, which offers identical functionality in an SO20 package. Designers must account for physical footprint differences when substituting packages while maintaining electrical compatibility.
