PI6ULS5V9617A Level Translating Fast-Mode Plus I2C-bus/SMbus Repeater Features Description  2-channel, bidirectional buffer isolates capacitance and The PI6ULS5V9617A is a CMOS integrated circuit intended for Fast-mode Plus (Fm+) I2C-bus or SMBus applications. It provides level shifting between low voltage (down to 0.6V) and higher voltage (2.2V to 5.5V) in mixed-mode applications. The PI6ULS5V9617A enables the system designer to isolate two halves of a bus for both voltage and capacitance, accommodating more I2C devices or longer trace length. It also permits extension of the I2C-bus by providing bidirectional buffering for both the data (SDA) and the clock (SCL) lines, thus enabling two buses of 540 pF at 1 MHz or up to 4000 pF at lower speeds. The SDA and SCL pins are overvoltage tolerant and are high-impedance when the PI6ULS5V9617A is un-powered. The 2.2V to 5.5V bus port B drivers have the static level offset, while the adjustable voltage bus port A drivers eliminate the static offset voltage. This results in a LOW on the port B translating into a nearly 0V LOW on the port A which accommodates the smaller voltage swings of lower voltage logic. The EN pin is referenced to VCC(B) and can also be used to turn the drivers on and off under system control.                 allows 540pF on either side of the device at 1 MHz and up to 4000 pF at lower speeds Voltage level translation from 0.6V to 5.5V and from 2.2V to 5.5V Footprint and functional replacement for PI6ULS5V9617A at Fast-mode speeds Port A operating supply voltage range of 0.6V to 5.5V with normal levels(0.4VCC(A) + 0.8V ≤ VCC(B) ) Port B operating supply voltage range of 2.2V to 5.5V with static offset level 5V tolerant I2C-bus and enable pins 0 Hz to 1 MHz clock frequency (the maximum system operating frequency may be less than 1MHz because of the delays added by the repeater) Active HIGH repeater enable input referenced to VCC(B) Open-drain input/outputs Latching free operation Supports arbitration and clock stretching across the repeater Accommodates Standard-mode, Fast-mode and Fast-mode Plus I2C-bus devices, SMBus (standard and high power mode), PMBus and multiple masters Powered-off high-impedance I2C-bus pins ESD protection exceeds 8000V HBM per JESD22-A114 Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3) For automotive applications requiring specific change control (i.e. parts qualified to AEC-Q100/101/200, PPAP capable, and manufactured in IATF 16949 certified facilities), please contact us or your local Diodes representative.
