Overview of PCA9655EMTTXG by onsemi
The PCA9655EMTTXG is an I2C-compatible, 16-bit, remote low voltage I/O port expander, housed in a WQFN-24 4×4 package with a 0.5mm pitch and provided on a 3000-reel. Manufactured by onsemi, this component is designed to provide additional I/O interfaces to microcontrollers or other I2C bus devices, extending the number of controllable I/O lines in a system. Its key features include a wide operating voltage range from 1.65V to 5.5V, making it versatile for both low and high-voltage applications. Additionally, it supports bus frequencies up to 1 MHz and interrupts I/O, enabling high-speed device communication and event notification, respectively. The expander is characterized by its small form factor (WQFN-24), accommodating tight PCB layouts.
In line with industry and environmental standards, PCA9655EMTTXG is RoHS compliant and is fabricated with a matte tin terminal finish. On the aspect of environmental resilience, it mentions an operating temperature range from -55 °C to +125 °C, signifying its capability to perform in both commercial and industrial environments. The part status is labeled as obsolete, which indicates that onsemi may have phased out this product, yet its relevance and potential usage in various applications remain significant. The part’s factory lead time is noted as 2 days, though this information is relevant as of the current time of writing and may change.
