Maxim MAX7318ATG+

16I²C, SMBusPOR2 В ~ 5,5 В-40°C ~ 125°C

Overview

The MAX7318ATG 2-wire-interfaced expander provides 16-bit parallel input/output (I/O) port expansion for SMBus and I2C applications. The MAX7318ATG consists of input port registers, output port registers, polarity inversion registers, configuration registers, and an I2C-compatible serial interface logic compatible with SMBus. The system master can invert the MAX7318ATG input data by writing to the active-high polarity inversion register. Any of the 16 I/O ports can be configured as an input or output. A power-on reset (POR) initializes the 16 I/Os as inputs. Three address select pins configure one of 64 slave ID addresses. The MAX7318ATG supports hot insertion. All port pins, the active-low INT output, SDA, SCL, and the slave address inputs AD0–2 remain high impedance in power-down (V+ = 0V) with up to 6V asserted upon them. The MAX7318ATG is available in 24-pin SO, SSOP, TSSOP, and thin QFN packages and is specified over the -40°C to +125°C automotive temperature range. For applications requiring an SMBus timeout function, refer to the MAX7311 data sheet.
