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 MAX7319,
MAX7321, MAX7322, or MAX7323.
Functional Overview
The MAX7322 is a general-purpose port expander
operating from +1.71V to +5.5V supply that provides
four push-pull output ports with 20mA sink, 10mA
source drive capability, and four input ports that are
overvoltage protected to +6V independent of supply volt-
age. The MAX7322 is rated to sink a total of 100mA and
source a total of 50mA from all four combined outputs.
The MAX7322 is set to one of 16 I2C slave addresses
(0x60 to 0x6F) using address inputs AD2 and AD0, 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 MAX7322.

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.

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.
