PI6ULS5V9617.pdfFEATURES
• 2 channel, bidirectional buffer isolates capacitance
and 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 I
2C-bus and enable pins
2C-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
• Package: MSOP-8L, SOIC-8L and TDFN2x3-8L
