Part Description: MAX7322 DS

Part Details:

19-3787; Rev 1; 9/06 EVALUATION KIT AVAILABLE I2C Port Expander with 4 Push-Pull Outputs and 4 Inputs MAX7322 General Description Features The MAX7322 2-wire serial-interfaced peripheral features 400kHz I2C Serial Interface four push-pull outputs and four input ports with selectable +1.71V to +5.5V Operation Voltage internal pullups. Input ports are overvoltage protected to 4 Push-Pull Output Ports Rated at 20mA Sink +6V and feature transition detection with interrupt output. Current The four input ports are continuously monitored for state 4 Input Ports with Maskable, Latching Transition changes (transition detection). The interrupt is latched, Detection allowing detection of transient changes. Any combination Input Ports are Overvoltage Protected to +6V of inputs can be selected using the interrupt mask to Transient Changes are Latched, Allowing assert the open-drain INT output. When the MAX7322 is Detection Between Read Operations subsequently accessed through the serial interface, any INT Output Alerts Change on Any Selection of pending interrupt is cleared. Inputs The four push-pull outputs are rated to sink 20mA, and AD0 and AD2 Inputs Select from 16 Slave are capable of driving LEDs. Addresses The RST input clears the serial interface, terminating any Low 0.6µA (typ) Standby Current I2C communication to or from the MAX7322. -40°C to +125°C Operating Temperature Range The MAX7322 uses two address inputs with four-levellogic to allow 16 I2C slave addresses. The slave address Ordering Information also sets the power-up default logic state for the four out-put ports, and enables or disables internal 40k pullupsfor the input ports. TEMP PIN- TOP PKG PART RANGE PACKAGE MARK CODE The MAX7322 is one device in a family of pin-compatibleport expanders with a choice of input ports, open-drain -40°C to MAX7322AEE+ 16 QSOP --
