74LVC244ADB-Q100J

Overview

The Nexperia 74LVC244ADB-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 accepts input voltages up to 5.5 V, enabling direct interfacing with 5 V logic in mixed-voltage environments. The device utilizes Schmitt-trigger inputs for noise tolerance and is housed in a 20-lead SOIC package (SOT163-1). It supports operation across extended temperature ranges from -40 °C to +85 °C and up to +125 °C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 specifications
• Five-volt tolerant inputs and outputs for mixed-voltage system integration
• Schmitt-trigger action on all data inputs to ensure signal integrity
• High-impedance output state when the supply voltage is zero

Applications

• Automotive electronic systems requiring robust logic buffering
• Mixed-voltage interfaces between 3.3 V and 5.0 V logic domains
• Octal bus drivers for high-speed data transmission lines

Procurement Notes

Verify that the specific ordering suffix matches the required package type and tape-and-reel configuration. Confirm the revision level of the product data sheet aligns with current design requirements. Ensure compliance with RoHS directives and REACH regulations for the intended market. Validate that the component's thermal dissipation characteristics meet the constraints of the final assembly environment.

Selection Notes

Select this component when an octal buffer with five-volt tolerance is required for automotive or industrial applications. The device is suitable for designs needing Schmitt-trigger inputs to handle slow signal transitions. Consider the SOIC-20 package dimensions for PCB layout compatibility. Verify that the operating temperature range meets the environmental conditions of the target application.

Part Context

This part belongs to the Nexperia 74LVC244A-Q100 family of octal buffers. It shares functional similarities with other members like the 74LVCH244AD-Q100J but lacks the bus-hold feature found in the LVCH variant. The device is designed to replace older generation logic families while offering improved power consumption and voltage flexibility.

Replacement Considerations

The 74LVCH244AD-Q100J serves as a compatible alternative within the same family, though it includes bus-hold functionality not present in the LVC version.
