Maxim Integrated (MAX7328AWE+) I/O Expander, 100 kHz

Product Overview The MAX7328AWE+ from Maxim Integrated 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 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. 100KHz, 5.5V tolerant, I2C compatible serial interface Operating temperature range from -40°C to +125°C 2.5V to 5.5V operating supply voltage range, 1.3V power-on reset voltage Low standby current consumption of 10µA (maximum) I2C bus to parallel port expander, 100KHz serial clock frequency Open-drain interrupt output active-low INT 8bit remote I/O port for the I2C bus Latched outputs with high current drive capability for directly driving LEDs Second sources to PCF8574 and PCF8574A Supply current (interface running) of 40µA Product Information Chip Configuration: - Bus Frequency: 100kHz IC Interface Type: I2C Supply Voltage Min: 2.5V Supply Voltage Max: 5.5V Interface Case Style: WSOIC No. of Pins: 16Pins No. of I/O's: 8I/O's Product Range: - Automotive Qualification Standard: - MSL: MSL 1 - Unlimited
