The PCA9517ADP,118 by NXP Semiconductors is a CMOS integrated circuit designed for level shifting in I2C-bus and SMBus applications. It provides bidirectional buffering for both data (SDA) and clock (SCL) lines, enabling extension of the I2C-bus and isolation of bus segments for voltage and capacitance.
This device supports operating voltages from 2.7V to 5.5V and can handle data rates up to 400kHz. The PCA9517A features overvoltage tolerant SDA and SCL pins, which are high-impedance when the device is unpowered. Its Port A drivers are designed to drive more current and eliminate static offset voltage, accommodating lower voltage logic swings. The Port B drivers are similar to those on the PCA9515A.
Designed for surface mount, the PCA9517ADP,118 comes in an 8-TSSOP package. It can be enabled via VCCA (above 0.8V) and VCCB (above 2.5V) or through an EN pin. Caution should be exercised to only change the enable pin state when the bus is idle. Multiple PCA9517A devices can be connected in series or in a star topography via Port A for flexible bus extension and isolation.
Key electrical characteristics include a maximum data rate of 400kHz, capacitance of 6 pF, and current draw of 5mA. The operating temperature range is -40°C to 85°C. The device offers robust ESD protection with an HBM rating greater than 5.5 kV.
