MAXIM INTEGRATED / ANALOG DEVICES MAX7315AUE 8-Port I/O Expander
The MAX7315AUE+ is an 8-port I/O expander with LED intensity control, interrupt, and hot insertion protection, housed in a 16-pin TSSOP package. It is compatible with I2C/SMBus protocols and provides microprocessors with eight configurable I/O ports. Each port can function as an open-drain current sinking output rated up to 50mA at 5.5V or as a logic input with transition detection. A ninth port is available for transition detection interrupt or as a general-purpose output. The outputs can directly drive LEDs or serve as logic outputs with external pull-up resistors up to 5.5V. The device features 8-bit PWM LED intensity control with global and individual adjustment, enabling 14 levels of coarse adjustment and 16 levels of fine adjustment per output. It supports LED status indication, RGB LED drivers, LCD backlights, and keypad backlights. Operating voltage ranges from 2V to 3.6V, with an operating temperature range of -40°C to 125°C. The serial interface supports up to 400Kbps and is compatible with PCA9534 and PCA9554(A) devices. It offers transition detection with interrupt output, automatic two-phase LED blinking, and low standby current. Inputs are overvoltage protected up to 5.5V, and the maximum port current is 50mA. The device is suitable for consumer electronics and portable device applications.
