The Texas Instruments TCA9555PWR is a 16-bit I2C/SMBus I/O expander in a 24-pin TSSOP package. It operates from a 1.65V to 5.5V supply at up to 400k Hz and includes an interrupt output, weak pull-ups, and configuration registers.
The TCA9555PWR is used to add general-purpose input/output pins to a system over the I2C bus, expanding control and status lines without extra processor pins. Embedded engineers apply it to drive LEDs, read switches, and control peripherals in consumer, industrial, and computing designs.
Fusion’s in-house quality hubs and Prosemi testing facility are fully certified to meet critical industry standards for electronic component inspection and testing.
