MAX7315ATE+T

MAX7315ATE+T is an 8-port I/O expander with LED intensity control, interrupt, and hot-insertion protection. The MAX7315 I2C-/SMBus-compatible serial interfaced peripheral provides microprocessors with 8 I/O ports. Each I/O port can be individually configured as either an open-drain current-sinking output rated at 50mA at 5.5V, or a logic input with transition detection. The MAX7315 is pin and software compatible with the PCA9534 and PCA9554(A). Each output has independent blink timing with two blink phases. All LEDs can be individually set to be on or off during either blink phase, or to ignore the blink control. The blink period is controlled by a register. Suitable for LCD backlights, LED status indication, portable equipment, laptop computers, keypad backlights, RGB LED drivers, cellular phones applications.
