Product Preview
Level-Translating I2C-Bus
Repeater
The PCA9517A is an I2Câbus repeater that provides level shifting
between low voltage (down to 0.9 V) and higher voltage (2.7 V to
5.5 V) for I2Câbus or SMBus applications.
Features
⢠2 Channel, Bidirectional Buffer Isolates Capacitance and Allows
400 pF on Either Side of the Device
⢠Voltage Level Translation from 0.9 V to 5.5 V and from 2.7 V to
5.5 V
⢠Footprint and Functional Replacement for PCA9515/15A
⢠I2Câbus and SMBus Compatible
⢠Active HIGH Repeater Enable
⢠OpenâDrain Inputs/Outputs
⢠Lockâup Free Operation
⢠Supports Arbitration and Clock Stretching Across the Repeater, and
Multiple Masters
⢠I2C and SMBus SCL Clock Frequency up to 1 MHz (The maximum
system operating frequency may be less than 1 MHz because of the
delays added by the repeater.)
⢠PoweredâOff HighâImpedance I2Câbus Pins
⢠A Side Operating Supply Voltage Range of 0.9 V to 5.5 V
⢠B Side Operating Supply Voltage Range of 2.7 V to 5.5 V
⢠5 V Tolerant I2Câbus and Enable Pins
⢠Available in: Microâ8, SOIC8
⢠ESD Performance: 8 kV HBM, 700 V MM, 2000 V CDM
⢠These are PbâFree Devices
