19-3785; Rev 0; 10/06 EVALUATION KIT AVAILABLE I2C Port Expander with Eight Push-Pull Outputs and Eight Inputs MAX7324 General Description Features The MAX7324 2-wire serial-interfaced peripheral fea- 400kHz, +6V-Tolerant I2C Serial Interface tures 16 I/O ports that are divided into eight push-pull +1.71V to +5.5V Operating Voltage outputs and eight inputs. Each input features selectable Eight Push-Pull Outputs internal pullups, overvoltage protection to +6V, andtransition detection with an interrupt output. Eight Input Ports with Maskable, Latching Transition Detection All input ports are continuously monitored for statechanges (transition detection). The interrupt is latched, Input Ports are Overvoltage Protected to +6V allowing detection of transient changes. Any combina- Transient Changes are Latched, Allowing tion of inputs can be selected using the interrupt mask Detection Between Read Operations to assert the INT output. When the MAX7324 is subse- INT Output Alerts Change on Any Selection of quently accessed through the serial interface, any Inputs pending interrupt is cleared. AD0 and AD2 Inputs Select from 16 Slave The push-pull outputs are rated to sink 20mA and are Addresses capable of driving LEDs. The RST input clears the serial Low 0.6µA Standby Current interface, terminating any I2C communication to or from -40°C to +125°C Temperature Range the MAX7324. The MAX7324 uses two address inputs with four-levellogic to allow 16 I2C slave addresses. The slaveaddress also enables or disables internal 40k pullups Ordering Information in groups of four ports. The MAX7324 is one device in a family of pin-compatible PIN- PKG PART TEMP RANGE port expanders with a choice of input ports, open-drain PACKAGE CODE I/O ports, and push-pull output ports (see Table 1). MAX7324AEG+ -40°C to +125°C 24 QSOP E24-1 The MAX7324 is available in 24-pin QSOP and TQFN 24 TQFN-EP* packages, and is specified over the -40°C to +125°C
