MAX7306/MAX7307 is an I2C-compatible, serial-interfaced four-level translating I/O device operating from 1.62V to 3.6V. The MAX7307 features a port supply (VLA) that allows level translation on I/O ports to operate from a separate power supply from 1.4V to 5.5V. The MAX7306 features an address select input (AD0) to allow up to four unique slave addresses. MAX7306/MAX7307 ports P2, P3 and P4 can be configured as inputs, push-pull outputs and open-drain outputs. Port P1 can be configured as a general-purpose input, open-drain output or an open-drain INT output. Ports P2 and P3 can be configured as OSCIN and OSCOUT respectively. The MAX7306/MAX7307 include an internal oscillator for PWM, blink and key debounce or to cascade multiple MAX7306/MAX7307s. The external clock can be used to set a specific PWM and blink timing. The RST input asynchronously clears the 2-wire interface and terminates a bus lockup involving the MAX7306/MAX7307. All ports configured as output feature 33-step PWM, allowing any output to be set from fully off, 1/32 to 31/32 duty cycle, to fully on. All output ports also feature LED blink control, allowing blink periods of 1/8 second, 1/4 second, 1/2 second, 1, 2, 4 or 8 seconds. Any port can blink during this period with a 1/16 to 15/16 duty cycle. MAX7306/MAX7307 are specified over the -40°C to +125°C temperature range and are available in 10-pin µDFN (2mm x 2mm) and 10-pin µMAX®.
