PCA9517D,118, Драйвер шины I2C одноканальный 400кГц

Описание PCA9517D,118 The PCA9517D, 118 is a level translating CMOS I?C-Bus Repeater provides level shifting between low voltage and higher voltage I?C-bus or SMBus applications. While retaining all the operating modes and features of the I?C-bus system during the level shifts, it also permits extension of the I?C-bus by providing bi-directional buffering for both the data (SDA) and the clock (SCL) lines, thus enabling two buses of 400pF. Using the repeater enables the system designer to isolate two halves of a bus for both voltage and capacitance. The SDA and SCL pins are overvoltage tolerant and are high-impedance when the repeater is unpowered. The 2.7 to 5.5V bus port-B drivers behave much like the drivers on this device, while the adjustable voltage bus port-A drivers drive more current and 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 smaller voltage swings of lower voltage logic. • Bidirectional buffer isolates capacitance and allows 400pF on either side of the device • Footprint and functional replacement • Active high individual repeater enable input • Open-drain input/outputs • Lock-up free operation • Supports arbitration and clock stretching across the repeater • Powered-off high-impedance I?C pins • Latch-up testing is done to JEDEC standard JESD78 which exceeds 100mA EU RoHSCompliantECCN (US)EAR99Part StatusActiveHTS8542.39.00.01TypeRepeaterMaximum Clock Frequency (kHz)400Input Signal TypeI2CTypical Input Capacitance (pF)6Minimum Operating Supply Voltage (V)0.9/2.7Maximum Operating Supply Voltage (V)5.5Typical Operating Supply Voltage (V)5|3.3|2.5|1.8Maximum Supply Current (mA)5Maximum Power Dissipation (mW)100Minimum Operating Temperature (°C)-40Maximum Operating Temperature (°C)85PackagingTape and ReelPin Count8Supplier PackageSOMountingSurface MountPackage Height1.45(Max)Package Length5(Max)Package Width4(Max)PCB changed8Lead ShapeGull-wingВес, г0.15
