It supports universal bidirectional voltage translation across ranges of 0.8V to 2.7V. The device includes IOFF circuitry for partial power-down mode, preventing damaging backflow currents. It offers 16mA drive capability at 2.5V and high ESD protection exceeding JESD22 standards. Operating temperatures range from -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Supports universal bidirectional voltage translation between independent supply rails
• Includes IOFF circuitry to disable outputs during partial power-down conditions
• Provides high electrostatic discharge protection exceeding JESD22 specifications

Translators, Level Shifters Applications

• Asynchronous communication between data buses with different voltage levels
• Partial-power-down applications requiring isolation during power cycles
• Low voltage system designs utilizing configurable supply rails

Translators, Level Shifters Procurement Notes

Verify the specific package variant required, as the 'E' suffix denotes Pb-free and Green manufacturing in the 48-pin TSSOP configuration. Confirm that the design accommodates the dual-supply rail architecture where both VCCA and VCCB operate within the 0.8V to 2.7V range. Ensure control pins are supplied by VCCA and that OE inputs are properly pulled up to maintain high impedance states during power-up or power-down sequences.

Translators, Level Shifters Selection Notes

Select this component when designing systems requiring bidirectional level shifting between low-voltage domains operating below 3.3V. The dual-supply architecture allows flexible voltage configurations on each port. Consider the IOFF feature if the application demands protection against back-feeding currents during partial power-down states. Verify that the 16mA drive capability meets the load requirements for the connected buses.
