PI6ULS5V9306ZEEX

Translators, Level Shifters Overview

The PI6ULS5V9306ZEEX is a dual bidirectional I2C-bus and SMBus voltage-level translator manufactured by Diodes Incorporated. It operates within an ambient temperature range of -40°C to +85°C. The device supports a low-voltage reference (VREF1) from 0.9V to 3.3V and a high-voltage reference (VREF2) from 1.8V to 5V. Input/output voltages on SCL and SDA pins are rated up to 5V. The package is an 8-pin TDFN2x3-8 (ZE).

Translators, Level Shifters Feature Summary

• Provides bidirectional translation between I2C and SMBus buses across different voltage domains.
• Features an enable pin (EN) for switching the internal pass-through channel on or off.
• Supports both open-drain and push-pull application configurations.

Translators, Level Shifters Applications

• Interfacing low-voltage logic devices with higher-voltage peripherals on I2C/SMBus networks.
• System designs requiring hot-swappable bus connections with level shifting capabilities.
• Embedded systems utilizing mixed-voltage architectures where signal integrity must be maintained across voltage boundaries.

Translators, Level Shifters Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the ZE suffix denotes the TDFN2x3-8 package which is marked as Not Recommended for New Design in official documentation. Confirm compliance with RoHS directives and check for any Product Change Notifications regarding manufacturing updates before finalizing procurement specifications.

Translators, Level Shifters Selection Notes

Select this component when designing circuits that require flexible voltage translation between 0.9V and 5V domains. Ensure the pull-up resistor values are calculated based on the specific VREF1 and VREF2 levels to maintain proper signal rise times. Verify that the load capacitance requirements align with the dynamic characteristics specified for the target operating frequency.

Translators, Level Shifters Part Context

This part belongs to the PI6ULS5V9306 family of voltage translators. While the core functionality remains consistent across the series, the ZE suffix specifically identifies the TDFN2x3-8 package variant. Other variants in the family include SOIC-8, MSOP-8, and X2-DFN-8 packages, offering flexibility for different PCB layout constraints.

Translators, Level Shifters Replacement Considerations

Direct substitutes within the same manufacturer's portfolio include other package variants of the PI6ULS5V9306 such as PI6ULS5V9306SS8-7 or PI6ULS5V9306HK3-7. Cross-manufacturer replacements should be evaluated carefully to ensure identical pinout compatibility and electrical performance parameters.

Translators, Level Shifters FAQ

Is the PI6ULS5V9306ZEEX suitable for new design implementations?

No, the datasheet explicitly marks the TDFN2x3-8 (ZE) package as 'Not Recommend for New Design'.

How does the EN pin function affect the device operation?

When the EN pin is pulled high, the switch is enabled, allowing signals to pass between the A and B sides. When pulled low, the device is disabled, isolating the two voltage domains.
