Product Description
PCAL6524HE Integrated Circuit Chip Ultra-Low-Voltage Translating 24-Bit Fm+ I²C-Bus/SMBus I/O Expander
PCAL6524HE is a 24-bit general purpose I/O expander that provides remote I/O expansion for many microcontroller families via the Fast-mode Plus (Fm+) I²C-bus interface. The ultra-low-voltage interface allows for direct connection to a microcontroller operating down to 0.8 V.
