com 19-3059; Rev 4; 4/05 16-Port I/O Expander with LED Intensity Control, Interrupt, and Hot-Insertion Protection General Description The MAX7313 I 2 C™-compatible serial interfaced peripheral provides microprocessors with 16 I/O ports.
Each I/O port can be individually configured as either an open-drain current-sinking output rated at 50mA and 5.
5V, or a logic input with transition detection.
A 17th port can be used for transition detection interrupt, or as a general-purpose output.
The outputs are capable of driving LEDs, or providing logic outputs with external resistive pullup up to 5.
5V.
PWM current drive is integrated with 8 bits of control.
Four bits are global contro...
