MAX7304

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-

pull GPIOs and four open-drain GPIOs configurable as

PWM-controlled LED drivers. The device supports a

1.62V to 3.6V separate power supply for level translation.

An address-select input (AD0) allows up to four unique

slave addresses for the device.

S Four LED Driver Pins on PORT15–PORT12

S Integrated High-ESD Protection

8kV IEC 61000-4-2 Contact Discharge

14kV IEC 61000-4-2 Air-Gap Discharge

S 5V Tolerant, Open-Drain I/O Ports Capable of

Constant-Current LED Drive

Each GPIO can be programmed to one of the two

externally applied logic voltage levels. PORT15–PORT12

can also be configured as LED drivers that feature

constant-current sinks and PWM intensity control with the

internal oscillator. The maximum constant-current level for

each open-drain LED port is 20mA. The intensity of the

LED on each open-drain port can be individually adjusted

through a 256-step PWM control. The port also features

LED fading.

S 256-Step PWM Individual LED Intensity-Control

Accuracy

S Individual LED Blink Rates and Common LED

Fade-In/Out Rates from 256ms to 4096ms

S User-Configurable Debounce Time (1ms to 32ms)

S Configurable Edge-Triggered Port Interrupt (INT)

S 1.62V to 3.6V Operating Supply Voltage

The same index rows and columns in the device can be

used as a direct logic-level translator.

S Individually Programmable GPIOs to Two Logic

Levels

The device is offered in a 24-pin (3.5mm x 3.5mm) TQFN

package with an exposed pad, and a small 25-bump

(2.159mm x 2.159mm) wafer-level package (WLP) for

cell phones, pocket PCs, and other portable consumer

electronic applications.

S 8-Channel Individual Programmable Level

Translators

S Supports Hot Insertion

S 400kbps, 5.5V Tolerant I²C Serial Interface with

Selectable Bus Timeout

The device operates over the -40NC to +85NC extended

temperature range.
