I C Port Expander with 12 Push-Pull Outputs

and 4 Open-Drain I/Os

The MAX7327 is set to two of 32 I C slave addresses

Detailed Description

(see Tables 2 and 3) using address inputs AD2 and

MAX7319–MAX7329 Family Comparison

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.

AD0, and is accessed over an I C serial interface up to

400kHz. Eight push-pull outputs use a different slave

address from the other four push-pull outputs and the

open-drain I/Os. The eight push-pull outputs, O8–O15,

use the 101xxxx addresses while the four outputs O0,

O1, O6, and O7 and the open-drain I/Os P2–P5 use

addresses with 110xxxx. The RST input clears the serial

interface in case of a bus lockup, terminating any serial

transaction to or from the MAX7327.

Functional Overview

The MAX7327 is a general-purpose port expander

operating from a +1.71V to +5.5V supply that provides

12 push-pull output ports with a 20mA sink, 10mA

source drive capability, and four open-drain I/O ports

with a 20mA sink capability. The four open-drain out-

puts are overvoltage protected to +6V.

Any of the four open-drain ports can be configured as a

logic input by setting the port output logic-high (logic-

high for an open-drain output is high impedance).

When the MAX7327 is read through the serial interface,

the actual logic levels at the ports are read back.

8 inputs and 8 push-pull outputs version:

8 input ports with programmable latching transition

detection interrupt and selectable pullups.

8 push-pull outputs with selectable default logic

levels.

MAX7324

Yes

—

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 if only for

a transient) since the ports were last read.

8 I/O and 8 push-pull outputs version:

101xxxx

and

110xxxx

8 open-drain I/O ports with latching transition

detection interrupt and selectable pullups.

8 push-pull outputs with selectable default logic

levels.

MAX7325

Up to 8

—

Up to 8

Open-drain outputs can level shift the logic-high

state to a higher or lower voltage than V+ using

external pullup resistors, but pullups draw current

when output is low. Any open-drain port can be used

as an input by setting the open-drain output to logic-

high. Transition flags identify which open-drain port

inputs have changed (even if only for a transient)

since the ports were last read.
