PCA9517D,118, Драйвер шины I2C одноканальный 400кГц

The PCA9517D, 118 is a level translating CMOS I²C-Bus Repeater provides level shifting between low voltage and higher voltage I²C-bus or SMBus applications. While retaining all the operating modes and features of the I²C-bus system during the level shifts, it also permits extension of the I²C-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 I²C pins • Latch-up testing is done to JEDEC standard JESD78 which exceeds 100mA EU RoHS Compliant ECCN (US) EAR99 Part Status Active HTS 8542.39.00.01 Type Repeater Maximum Clock Frequency (kHz) 400 Input Signal Type I2C Typical Input Capacitance (pF) 6 Minimum Operating Supply Voltage (V) 0.9/2.7 Maximum Operating Supply Voltage (V) 5.5 Typical Operating Supply Voltage (V) 5|3.3|2.5|1.8 Maximum Supply Current (mA) 5 Maximum Power Dissipation (mW) 100 Minimum Operating Temperature (°C) -40 Maximum Operating Temperature (°C) 85 Packaging Tape and Reel Pin Count 8 Supplier Package SO Mounting Surface Mount Package Height 1.45(Max) Package Length 5(Max) Package Width 4(Max) PCB changed 8 Lead Shape Gull-wing Вес, г 0.15 NXP / Philips
