MAXIM INTEGRATED PRODUCTS MAX7325ATG+ 输入/输出扩展, 400 kHz, I2C, 1.71 V, 5.5 V, TQFN
The is an I2C port expander with 8 push-pull and 8 open-drain I/Os in 24 pin TQFN package. This 2-wire serial interfaced peripheral device has 16 I/O ports. Ports are divided into eight push-pull outputs and eight I/Os with selectable internal pull-ups and transition detection. Eight ports are push-pull outputs and eight I/Os may be used as a logic input or an open-drain output. All I/O ports configured as inputs are continuously monitored for state changes transition detection. State changes are indicated by active-low INT output. The interrupt is latched allowing detection of transient changes. The active-low RST input clears serial interface by terminating any I2C communication to or from MAX7325. It uses two address inputs with four level logic to allow 16 I2C slave addresses. The slave address also determines power-up logic state for I/O ports and enables or disables internal 40Kohm pull-ups in groups of four ports.
