Product Description
The NXP PCA9517AD,118 is a specialized 2-channel I/O Expander IC offered in a compact SO 8 surface mount package, designed for voltage level shifting in I2C and SMBus environments where supply voltages range from as low as 0.9V to 5.5V.
This device enables seamless communication between buses operating at different voltage levels by providing bidirectional buffering on both the data (SDA) and clock (SCL) lines, supporting clock frequencies up to 400kHz. Its lock-up free operation and open-drain I/O ensure reliable, high-integrity signal transmissions.
With an 8-pin package measuring 5mm in length and 1.75mm in height, the PCA9517AD,118 is optimized for space-constrained industrial and electronic applications. It supports operating temperatures from -40°C to 85°C, making it suitable for harsh environmental conditions.
This semiconductor component fits well into electronic devices requiring level shifting and extended I2C bus functionality such as industrial controllers, embedded systems, and other communication devices. It is mounted using standard surface mount technology, allowing easy integration into automated manufacturing processes.
Operates up to 400kHz clock frequency for fast data transfer. Voltage supply range from 0.9V to 5.5V supports diverse system requirements. Two I/O channels provide level shifting and buffering for I2C buses. Compact SO 8 package with dimensions ideal for PCB designs.
Wide temperature rating suitable for industrial and commercial use. Open-drain input/output and lock-up free operation enhance reliability. Surface mount device compatible with modern PCB assembly processes. Maintains compliance with I2C communication protocols.
This product is ideal for use in electronics manufacturing, industrial automation, embedded systems, and communication equipment where level shifting and signal integrity across different voltage domains are critical.
