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 MAX7319 is a general-purpose port expander,
operating from a +1.71V to +5.5V supply that provides
eight CMOS input ports that are overvoltage protected
to +6V independent of supply voltage.
The MAX7319 is set to one of 16 I2C slave addresses
(0x60 to 0x6F) using the address-select inputs AD2
and AD0, and is accessed over an I2C serial interface.
The RST input clears the serial interface in case of a
hung bus, terminating any serial transaction to or from
the MAX7319.
The input ports offer latching transition detection func-
tionality. All input ports are continuously monitored for

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 levels.
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.
