PCA9518PWR Description

Short technical summary and product information.

The PCA9518PWR from Texas Instruments is an expandable, five-channel, bidirectional buffer and hub specifically designed for I2C and SMBus communication protocols. This device supports a wide operating voltage range of 3V to 3.6V and can handle frequencies up to 400kHz.

 

Key features include active-high individual repeater enable inputs, open-drain input/outputs, and lockup-free operation. The PCA9518PWR is designed to support multiple masters and offers powered-off high-impedance I2C pins. It is compatible with both I2C and SMBus standards.

 

This component is housed in a 20-TSSOP package, suitable for surface mount applications. Its design considerations include latchup performance exceeding 100 mA per JESD 78 and ESD protection exceeding JESD 22 standards, including 2000-V Human-Body Model (A114-A), 200-V Machine Model (A115-A), and 1000-V Charged-Device Model (C101).

 

The PCA9518 is an expandable five-channel bidirectional buffer for I2C and SMBus applications. The I2C protocol requires a maximum bus capacitance of 400 pF, which is derived from the device's buffering capabilities.
