SMBus/I 2 C Interfaced 4-Port, Level-Translating
GPIOs and LED Drivers
Slave Address
The MAX7307 is set to slave address 0x98 and the
MAX7306 can be set to one of four I 2 C slave addresses
0x98 to 0x9F, using the address input AD0 (see Table 5)
and is accessed over an I 2 C or SMBus serial interface.
The MAX7306 slave address is determined on each I 2 C
transmission, regardless of the transmission actually
addressing the device or not. The MAX7306 distin-
guishes whether address input AD0 is connected to
SDA, SCL, V DD , or GND during the transmission.
Therefore, the MAX7306 slave address can be config-
ured dynamically in an application without toggling the
device supply.
I/O Port Registers
The port I/O registers set the I/O ports, one register per
port (see Tables 6 and 7). Use the I/O port registers to
configure the ports individually as inputs, open-drain, or
push-pull outputs. Port P1 can only be configured as an
input or an open-drain output. The push-pull bit (D6) set-
ting for the port I/O register P1 is ignored.
I/O Input Port
Configure a port as an input by writing a logic-high to the
MSB (bit D7) of the port I/O register (see Table 6). To
obtain the logic level of the port input, read the port I/O
register bit, D0. This readback value is the instantaneous
logic level at the time of the read request if debounce is

disabled for the port (port I/O register bit D2 = 0), or the
debounced result if debounce is enabled for the port
(port I/O register bit D2 = 1). See Figure 1 for input port
structure.

I/O Output Port
Configure a port as an output by writing a logic-low to the
MSB (bit D7) of the port I/O register. The device reads
back the logic level, PWM, or the blink setting of the port
(see Table 7).

FUNCTION
Sets the I/O port as an input.
Refers the input to the V LA supply voltage.
Refers the input to the V DD supply voltage.
Disables the transition interrupt.
Enables the transition interrupt.
Do not write to these registers.
Disables debouncing of the input port.
Enables debouncing of the input port.
No transition has occurred since the last port read.
A transition has occurred since the last port read.
Port input is logic-low.
Port input is logic-high.
* Bit D6 controls the I/O’s supply reference for the MAX7307. The MAX7306 ignores bit D6.
