Maxim Integrated (MAX7319AEE+) I/O Expander, 400 kHz

Product Overview The MAX7319AEE+ from Maxim Integrated Products is an I2C port expander with eight inputs and maskable transition detection in 16 pin QSOP package. This 2-wire serial interfaced peripheral feature eight input ports with selectable internal pull-ups, overvoltage protection to +6V and transition detection with interrupt output. All input ports are continuously monitored for state changes (transition detection). The +5.5V tolerant RST (active-low) input clears the serial interface, terminating any I2C communication to or from the MAX7319. Operating voltage range from +1.71V to +5.5V Operating temperature range from -40°C to 125°C Interrupt mask 400KHz, +5.5V tolerant I2C serial interface Eight input ports with maskable, latching transition detection Input ports are overvoltage protected to +6V Transient changes are latched allowing detection between read operations INT output alerts change on any selection of inputs Low 0.6µA (typ) standby current, 1.6V power-on reset voltage Product Information Chip Configuration: - Bus Frequency: 400kHz IC Interface Type: I2C Supply Voltage Min: 1.71V Supply Voltage Max: 5.5V Interface Case Style: QSOP No. of Pins: 16Pins No. of I/O's: 8I/O's Product Range: - Automotive Qualification Standard: - MSL: MSL 1 - Unlimited
