Detailed Description
MAX7319–MAX7329 Family Comparison
The MAX7319–MAX7323 family consists of five pin-
compatible, eight-port expanders. Each version is opti-
mized for different applications. The MAX7328 and
MAX7329 are second sources to the PCF8574 and
PCF8574A.
The MAX7324–MAX7327 family consists of four pin-
compatible, 16-port expanders that integrate the func-
tions of the MAX7320 and one of either the MAX7319,
MAX7321, MAX7322, or MAX7323.
Functional Overview
The MAX7320 is a general-purpose port expander
operating from a +1.71V to +5.5V supply that provides
eight push-pull output ports. The MAX7320 is rated to
sink a total of 100mA and source a total of 50mA from
all eight combined outputs.
The MAX7320 is set to one of 16 I2C slave addresses
(0x50 to 0x5F) using address select inputs AD0 and AD2,
and is accessed over an I2C serial interface up to
400kHz. Note the MAX7320 offers a different range of I2C
slave addresses than the MAX7319, MAX7321,
MAX7322, and MAX7323 (these expanders use the
address range 0x60 to 0x6F).

Input-only versions:
Eight input ports with programmable latching
transition detection interrupt and selectable pullups.
Offers maximum versatility for automatic input
monitoring. An interrupt mask selects which inputs
cause an interrupt on transitions, and transition flags
identify which inputs have changed (even
momentarily) since the ports were last read.

Output-only versions:
Eight push-pull outputs with selectable power-up
default states.
Push-pull outputs offer faster rise time than open-
drain outputs, and require no pullup resistors.

I/O versions:
Eight open-drain I/O ports with latching transition
detection interrupt and selectable pullups.
Open-drain outputs can level shift the logic-high
state to a higher or lower voltage than V+ using
external pullup resistors. Any port can be used as an
input by setting the open-drain output to logic-high.
Transition flags identify which inputs have changed
(even momentarily) since the ports were last read.

Four input-only, four output-only versions:
Four input ports with programmable latching
transition detection interrupt and selectable pullups.
Four push-pull outputs with selectable power-up
default levels.
