74LVC244AD-Q100J

Overview

The Nexperia 74LVC244AD-Q100J is an octal non-inverting buffer and line driver featuring three-state outputs, qualified to AEC-Q100 Grade 1 standards for automotive use. It operates within a supply voltage range of 1.2 V to 3.6 V and supports inputs up to 5.5 V. The device utilizes Schmitt-trigger action at all inputs to tolerate slow rise and fall times. It is housed in a SO20 plastic small outline package (SOT163-1) with a body width of 7.5 mm. Operating temperatures are specified from -40 °C to +125 °C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Three-state outputs controlled by active-low enable inputs
• Schmitt-trigger inputs provide tolerance for slow signal transitions
• High-impedance state maintained when supply voltage is zero

Applications

• Interfacing between mixed 3.3 V and 5 V logic environments
• Clock distribution and buffering in automotive systems
• Data bus driving applications requiring high noise immunity

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and temperature grade. Confirm that the component meets the required AEC-Q100 Grade 1 specifications for your target application. Cross-reference the datasheet revision date to ensure compatibility with your design requirements.

Selection Notes

Select this component for designs requiring robust automotive-grade buffering with wide voltage tolerance. Ensure the system operates within the 1.2 V to 3.6 V supply range. Verify that the SO20 package dimensions fit the PCB layout constraints. Consider the Schmitt-trigger input characteristics if the application involves signals with slow transition rates.

Part Context

This part belongs to the 74LVC244A-Q100 family of octal buffers. It shares functional similarities with other 74-series logic devices but is specifically optimized for low-voltage CMOS operation. The Q100 suffix indicates automotive qualification, distinguishing it from standard commercial variants.

Replacement Considerations

Direct replacements include the 74LVCH244AD-Q100J, which offers identical functionality with added bus hold features on data inputs. Other compatible options within the same family may vary in package or specific electrical characteristics.
