MAX7319AEE+

The MAX7319AEE+ 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. Ideally used at cell phones, SAN/NAS, servers, notebooks and satellite radio.

• 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
