The PCA9518PW from Texas Instruments is an expandable, five-channel, bidirectional buffer and hub for I2C and SMBus applications. It facilitates communication in systems requiring signal buffering and expansion for the I2C protocol, which has a maximum bus capacitance limit.
This device operates with a supply voltage range of 3V to 3.6V and supports a maximum bus frequency of 400kHz. Key features include active-high individual repeater enable inputs, open-drain input/outputs, and lockup-free operation. It is designed to support multiple masters and offers powered-off high-impedance I2C pins.
The PCA9518PW is available in a 20-TSSOP surface mount package. Its design includes 5-V tolerant I2C and enable input pins, enabling mixed-mode signal operation. The component also provides robust ESD protection, exceeding 2000V for the Human-Body Model, 200V for the Machine Model, and 1000V for the Charged-Device Model.
This buffer is suitable for applications needing to extend I2C bus length or connect multiple devices, ensuring signal integrity and reliable communication in complex electronic systems.
