PI6ULS5V9306QV8-7

Clock Buffers, Drivers Overview

The PI6ULS5V9306QV8-7 is a dual bidirectional I2C-bus and SMBus voltage-level translator manufactured by Diodes Incorporated. It facilitates communication between low-voltage (VREF1: 0.9V to 3.3V) and high-voltage (VREF2: 1.8V to 5V) domains using SCL and SDA lines. The device operates within an ambient temperature range of -40°C to +85°C. Key electrical parameters include a maximum propagation delay of 1.4ns at 50pF load, an ON-state resistance of up to 140Ω at lower enable voltages, and an input clamping voltage of -1.2V. It supports both open-drain and push-pull configurations.

Clock Buffers, Drivers Feature Summary

• Dual bidirectional translation for I2C/SMBus SCL and SDA lines
• Supports VREF1 (0.9V–3.3V) and VREF2 (1.8V–5V) operating ranges
• Low ON-state resistance with configurable enable control via Pin 8
• ESD protection rated at 4000V in HBM mode

Clock Buffers, Drivers Applications

• Interfacing low-voltage microcontrollers with 5V peripheral devices
• Voltage level shifting in mixed-signal embedded systems
• I2C bus expansion across different voltage domains

Clock Buffers, Drivers Procurement Notes

Verify the package code 'V' corresponds to the VSSOP-8 form factor required for the specific PCB layout. Confirm that the ordering suffix '-7' indicates the standard tape and reel packaging quantity. Ensure the application environment remains within the specified -40°C to +85°C operating temperature range to maintain guaranteed dynamic characteristics.

Clock Buffers, Drivers Selection Notes

Select this component when bidirectional translation between 1.8V/2.5V/3.3V and 5V logic levels is required for I2C or SMBus protocols. Consider the maximum allowable ON-state resistance based on the pull-up resistor values and sink current requirements. Verify that the available space accommodates the VSSOP-8 package dimensions and that the EN pin can be properly biased to activate the pass switch.
