NXP (PCA9517ADP,118) Bus Repeater, 0.9 V to 5.5 V, TSSOP-8

Product OverviewThe PCA9517ADP is a CMOS Integrated Circuit that provides level shifting betweenlow voltage (down to 0.9V) and higher voltage (2.7V to 5.5V) I²C-bus or SMBusapplications. While retaining all the operating modes and features of theI²C-bus system during the level shifts, it also permits extension of the I²C-busby providing bidirectional buffering for both the data (SDA) and the clock (SCL)lines, thus enabling two buses of 400pF. Using the PCA9517A enables the systemdesigner to isolate two halves of a bus for both voltage and capacitance. TheSDA and SCL pins are overvoltage tolerant and are high-impedance when thePCA9517A is unpowered. The 2.7V to 5.5V bus port B drivers behave much like thedrivers on the PCA9515A device, while the adjustable voltage bus port A driversdrive more current and eliminate the static offset voltage. This results in alow on the port B translating into a nearly 0V low on the port A whichaccommodates smaller voltage swings of lower voltage logic.2-channel Bidirectional buffer isolates capacitance and allows 400pF on eitherside of deviceI²C-bus and SMBus compatibleActive high repeater enable inputOpen-drain input/outputsLock-up free operationSupports arbitration and clock stretching across repeaterAccommodates Standard-mode and Fast-mode I²C-bus devices and multiple mastersPowered-off high-impedance I²C-bus pins5V tolerant I²C-bus and enable pinsLatch-up testing is done to JEDEC standard JESD78 that exceeds 100mAApplicationsIndustrialProduct InformationLogic Family / Base Number: -Logic Device Type: BidirectionalLogic Case Style: TSSOPNo. of Pins: 8PinsSupply Voltage Min: 900mVSupply Voltage Max: 5.5VLogic IC Family: -Logic IC Base Number: -Operating Temperature Min: -40°COperating Temperature Max: 85°CProduct Range: -Automotive Qualification Standard: -MSL: -
