Product Description

The PI6ULS5V9517A is a CMOS integrated circuit intended for I2C-bus or SMBus applications. It can provide level shifting between low voltage (down to 0.8 V) and higher voltage (2.2V to 5.5V) in mixed-mode applications. And it enables I2C and similar bus system to be extended, without degeradation of peformance even during level shifting.

The PI6ULS5V9517A 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 allowing two buses of 400 pF to be connected in an I2C application. 

Features

  • 2 channel, bidirectional buffer
  • I2C-bus and SMBus compatible
  • Port A operating supply voltage range of 0.8 V to 5.5 V
  • Port B operating supply voltage range of 2.2 V to 5.5 V
  • Voltage level translation from 0.8 V to 5.5 V and from 2.2 V to 5.5 V
  • Active HIGH repeater enable input
  • Open-drain input/outputs
  • Lock-up free operation
  • Supports arbitration and clock stretching across the repeater
  • Accommodates Standard-mode and Fast-mode I2C-bus devices and multiple masters
  • Powered-off high-impedance I2C-bus pins
  • 5.5 V tolerant I2C-bus and enable pins
  • 0 Hz to 400 kHz clock frequency (the maximum system operating frequency may be less than 400 kHz because of the delays added by the repeater)
  • ESD protection exceeds 8KV HBM per JESD22- A114
  • Package: MSOP-8L, SOIC-8L and TDFN2x3-8L
