74LVC245APW-Q100J

Overview

The Nexperia 74LVC245APW-Q100J is an octal bus transceiver with 3-state outputs, designed for automotive applications. It operates within a supply voltage range of 1.2 V to 3.6 V and features 5 V tolerant inputs/outputs for interfacing with 5 V logic. The device includes Schmitt-trigger action at all inputs, IOFF circuitry for partial power-down mode operation, and complies with AEC-Q100 Grade 1 qualification. It is housed in a TSSOP20 package (SOT360-1) and supports temperatures from -40 °C to +125 °C.

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• IOFF circuitry provides partial Power-down mode operation
• Wide supply voltage range from 1.2 V to 3.6 V
• 5 V tolerant inputs/outputs for interfacing with 5 V logic

Applications

• Mixed 3.3 V and 5 V environments
• Partial power down applications
• Automotive applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature range. Confirm that the component meets the required AEC-Q100 Grade 1 standards for your intended application. Cross-reference the datasheet revision history to ensure you are using the most current specifications and electrical characteristics before finalizing procurement.

Selection Notes

Select this component when an octal bus transceiver with 3-state outputs is required for mixed-voltage systems. Ensure the design accommodates the 1.2 V to 3.6 V supply voltage range and utilizes the IOFF feature if partial power-down functionality is needed. Verify that the TSSOP20 package dimensions fit the PCB layout constraints and that the operating temperature range covers the environmental conditions.

Part Context

This part belongs to the 74LVC/LVCH245A-Q100 family of octal bus transceivers. It shares functional similarities with other members like the 74LVCH245A-Q100 but differs in specific features such as bus hold capabilities. The 'PW' suffix indicates the TSSOP20 package, while 'Q100J' denotes automotive qualification and specific packaging details.

Replacement Considerations

Check for direct substitutes within the same family, such as the 74LVCH245A-Q100, noting differences in features like bus hold. Verify pin compatibility and electrical characteristics against the target application requirements before substitution.
