Description

The PI6ULS5V9617B is a CMOS integrated circuit intended for Fast-mode Plus (Fm+) I
2C-bus or SMBus applications. It can provide level shifting between low voltage (down to 0.6V) and higher voltage (2.2V to 5.5V) in mixed-mode applications. The PI6ULS5V9617B 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 PI6ULS5V9617B is unpowered. 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.

Feature(s)

    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)
