74LVC245AD,112

Overview

The Nexperia 74LVC245AD,112 is an octal bus transceiver with 3-state outputs. It operates on a supply voltage range of 1.2 V to 3.6 V and features overvoltage tolerant inputs up to 5.5 V. The device includes Schmitt-trigger action for noise immunity and IOFF circuitry for partial power-down protection. It supports mixed 3.3 V and 5 V environments and complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36.

Feature Summary

• Bidirectional data transmission with direction control via DIR pin
• Overvoltage tolerant inputs allowing interface with 5 V devices
• IOFF circuitry prevents damaging backflow current during power-down
• Schmitt-trigger inputs provide tolerance for slow rise and fall times

Applications

• Mixed 3.3 V and 5 V system interfaces
• Octal bidirectional bus communication
• Partial power-down mode applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. Ensure compatibility with the target PCB footprint and thermal requirements. Confirm that the component meets all necessary regulatory standards for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring bidirectional data transfer between different voltage domains. The wide supply voltage range and overvoltage tolerance make it suitable for interfacing low-voltage logic with higher voltage peripherals. Consider the package options available for the specific board space constraints.
