Part Details:

19-2438; Rev 6; 4/06 4-Wire-Interfaced, 2.5V to 5.5V, 20-Port and 28-Port I/O Expander MAX7301 General Description Features The MAX7301 compact, serial-interfaced I/O expander High-Speed 26MHz SPI-/QSPI-TM/MICROWIRETM- (or general-purpose I/O (GPIO) peripheral) provides Compatible Serial Interface microprocessors with up to 28 ports. Each port is indi-vidually user configurable to either a logic input or logic 2.5V to 5.5V Operation output. -40°C to +125°C Temperature Range Each port can be configured either as a push-pull logic 20 or 28 I/O Ports, Each Configurable as output capable of sinking 10mA and sourcing 4.5mA,or a Schmitt logic input with optional internal pullup. Push-Pull Logic Output Seven ports feature configurable transition detection Schmitt Logic Input logic, which generates an interrupt upon change of port Schmitt Logic Input with Internal Pullup logic level. The MAX7301 is controlled through an 11µA (max) Shutdown Current SPITM-compatible 4-wire serial interface. Logic Transition Detection for Seven I/O Ports The MAX7301AAX and MAX7301ATL have 28 ports andare available in 36-pin SSOP and 40-pin TQFN packages,respectively. The MAX7301AAI has 20 ports and is avail- Ordering Information able in a 28-pin SSOP package. For a 2-wire I2C*-interfaced version, refer to the PIN- PKG MAX7300 data sheet. PART TEMP RANGE PACKAGE CODE For a pin-compatible port expander with additional MAX7301AAI+ -40°C to +125°C 28 SSOP A28-1 24mA constant-current LED drive capability, refer to the MAX7301AAX+ -40°C to +125°C 36 SSOP A36-4 MAX6957 data sheet. MAX7301ATL+ -40°C to +125°C 40 TQFN T4066- 5 +Denotes lead-free package. Applications Typical Operating Circuit
