NXP PCA9517DP118 Level Shifter
The PCA9517DP,118 is a CMOS I²C-bus repeater designed for level shifting between low voltage and higher voltage I²C or SMBus applications. It provides bidirectional buffering for both data (SDA) and clock (SCL) lines, enabling the extension of the I²C bus by supporting two buses with a capacitance of up to 400pF each. The device allows system designers to isolate sections of a bus for voltage and capacitance considerations. Its SDA and SCL pins are overvoltage tolerant and remain high-impedance when unpowered. Key features include bidirectional buffering, open-drain I/O, support for arbitration and clock stretching, and lock-up free operation. The device is a footprint and functionally compatible replacement for similar components, tested to JEDEC standards for latch-up with thresholds exceeding 100mA. Applications include communication and networking equipment.
