addresses (101xxxx) than the MAX7319, MAX7321,

MAX7322, and MAX7323 (110xxxx).

The RST input clears the serial interface in case of a

hung bus, ter5inating any serial transaction to or fro5

the MAX7320.

The MAX7320 slave address is deter5ined on each I²C

trans5ission, regardless of whether the trans5ission is

actually addressing the MAX7320. The MAX7320 distin-

guishes whether address inputs AD0 and AD2 are con-

nected to SDA or SCL instead of fixed logic levels V+

or GND during this trans5ission. This 5eans that the

MAX7320 slave address can be configured dyna5ical-

ly in the application without cycling the device supply.

When the MAX7320 is read through the serial interface,

the actual logic states at the ports are read back.

Output port power-up logic states are selected by the

address select inputs AD0 and AD2. Ports default to

logic-high or logic-low on power-up in groups of four

(see Table 3).

RST Input

On initial power-up, the MAX7320 cannot decode the

address inputs AD0 and AD2 fully until the first I²C

trans5ission. AD0 and AD2 initially appear to be con-

nected to V+ or GND. This is i5portant because the

address selection deter5ines the power-up logic levels

of the output ports. However, at power-up, the I²C SDA

and SCL bus interface lines are high i5pedance at the

pins of every device (5aster or slave) connected to the

bus, including the MAX7320. This is guaranteed as part

of the I²C specification. Therefore, address inputs AD0

and AD2 that are connected to SDA or SCL nor5ally

appear at power-up to be connected to V+. The power-

up output state selection logic uses AD0 to select the

power-up state for ports O3–O0, and uses AD2 to

select the power-up state for ports O7–O4. The rule is

that a logic-high, SDA, or SCL connection selects a

The RST input voids any I C transaction involving the

MAX7320 and forces the MAX7320 into the I C STOP

condition. A reset does not change the contents of the

output register. RST is overvoltage tolerant to +ꢀ.ꢀV.

Standby Mode

When the serial interface is idle, the MAX7320 auto5at-

ically enters standby 5ode, drawing 5ini5al supply

current.

Slave Address and Power-Up

Default Logic States

Address inputs AD0 and AD2 deter5ine the MAX7320

slave address and set the power-up output logic states.

Power-up logic states are set in groups of four (see

Table 3). The MAX7320 uses a different range of slave
