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 industry-standard parts.
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 MAX7323 is a general-purpose port expander, oper-
ating from a +1.71V to +5.5V supply, that provides four
push-pull output ports with 20mA sink, 10mA source drive
capability, and four open-drain I/O ports with a 20mA sink
capability. The four open-drain outputs are overvoltage
protected to +6V independent of supply voltage.
The MAX7323 is set to one of 16 I2C slave addresses
(0x60 to 0x6F) using the address select inputs AD0 and
AD2, and is accessed over an I2C serial interface up to
400kHz. The RST input clears the serial interface in
case of a bus lockup, terminating any serial transaction
to or from the MAX7323.

MAX7319

8
Yes
Input-only versions:
8 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.
MAX7320

8
Output-only versions:
8 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.

Up to 8
Up to 8
I/O versions:
8 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.

detection interrupt and selectable pullups;
4 push-pull outputs with selectable power-up default
levels.
