MAX7328AWE+

输入/输出扩展, 100 kHz, I2C, 2.5 V, 5.5 V, WSOIC

The from Products is an I2C port expander with eight I/O port in 16 pin WSOIC package. This is a 2-wire serial interfaced peripheral with eight I/O ports. Any port can be used as a logic input or an open-drain output. All input ports are continuously monitored for state changes transition detection. Transitions are alerted through the open-drain, 5.5V tolerant active-low INT output. The MAX7328 has a slave ID range of 0100xxx 0x20 to 0x27. The MAX7328 is a member of a family of pin compatible port expanders with a choice of input ports, open-drain I/O ports and push-pull output ports. It can be addressed by three hardware address pins for use of up to eight devices up to 16 using both MAX7328/MAX7329. It is used in RAID, servers, notebooks and industrial.
