DESCRIPTION

· The PI6ULS5V9617A is a CMOS integrated circuit designed for Fast-mode Plus (Fm+) I2C-bus or SMBus applications, facilitating level shifting between low voltage (down to 0.6V) and higher voltage (2.2V to 5.5V) in mixed-mode applications.
· It isolates two halves of a bus for both voltage and capacitance, allowing more I2C devices or longer trace lengths.
· The device provides bidirectional buffering for both the data (SDA) and the clock (SCL) lines, enabling two buses of 540 pF at 1 MHz or up to 4000 pF at lower speeds.
· The SDA and SCL pins are over-voltage tolerant and high-impedance when un-powered.
· The 2.2V to 5.5V bus port B drivers have a static level offset, while the adjustable voltage bus port A drivers eliminate the static offset voltage, translating a LOW on port B into a nearly 0V LOW on port A.
· The EN pin, referenced to VCC(B), can turn the drivers on and off under system control.

FEATURES

· 2-channel bidirectional buffer isolates capacitance, allowing 540pF on either side 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 operates at 0.6V to 5.5V; Port B operates at 2.2V to 5.5V with static offset level.
· 5V tolerant I2C-bus and enable pins.
· Clock frequency from 0 Hz to 1 MHz.
· Active HIGH repeater enable input referenced to VCC(B).
