MAX7304 2 I C-Interfaced 16-Port, Level-Translating GPIO and LED Driver with High Level of Integrated ESD Protection General Description Features The MAX7304 consists of 16 port GPIOs, with 12 push- S Four LED Driver Pins on PORT15PORT12 pull GPIOs and four open-drain GPIOs configurable as S Integrated High-ESD Protection PWM-controlled LED drivers. The device supports a 8kV IEC 61000-4-2 Contact Discharge 1.62V to 3.6V separate power supply for level translation. 15kV IEC 61000-4-2 Air-Gap Discharge An address-select input (AD0) allows up to four unique slave addresses for the device. S 5V Tolerant, Open-Drain I/O Ports Capable of Each GPIO can be programmed to one of the two Constant-Current LED Drive externally applied logic voltage levels. PORT15PORT12 S 256-Step PWM Individual LED Intensity-Control can also be configured as LED drivers that feature Accuracy constant-current sinks and PWM intensity control with the S Individual LED Blink Rates and Common LED internal oscillator. The maximum constant-current level for Fade-In/Out Rates from 256ms to 4096ms each open-drain LED port is 20mA. The intensity of the S User-Configurable Debounce Time (1ms to 32ms) LED on each open-drain port can be individually adjusted through a 256-step PWM control. The port also features S Configurable Edge-Triggered Port Interrupt (INT) LED fading. S 1.62V to 3.6V Operating Supply Voltage The same index rows and columns in the device can be S Individually Programmable GPIOs to Two Logic used as a direct logic-level translator. Levels The device is offered in a 24-pin (3.5mm x 3.5mm) TQFN S 8-Channel Individual Programmable Level package with an exposed pad, and a small 25-bump Translators (2.159mm x 2.159mm) wafer-level package (WLP) for S Supports Hot Insertion cell phones, pocket PCs, and other portable consumer electronic applications. 2 S 400kbps, 5.5V Tolerant I C Serial Interface with Selectable Bus Timeout The device operates over the -40NC to +85NC extended temperature range.
