AAT4296/98
Five/Six Channel Push/Pull I/O Expander
General Description
Features
SmartSwitch
The AAT4296/98 SmartSwitch is a member of
AnalogicTech's Application Specific Power MOS-
• VIN Range: 1.8V to 5.5V
• Independent Push/Pull Channels
FET™ (ASPM™) product family. The AAT4296/98
— AAT4296: Five Channels
is comprised of five/six push/pull output switches
— AAT4298: Six Channels
that gate each respective output between a common

I/O expansion applications, but can also be used for
• Optional Fast Auto-Discharge
a combination of general purposes to simplify power
• Low Quiescent Current: 3µA Typical
switching with an off state load discharge.
• Temperature Range: -40°C to +85°C
The AAT4296/98 operates over an input voltage
range of 1.8V to 5.5V, making it ideal for battery-
powered applications. The state of each output
channel is controlled with a single GPIO via the
• Available in Pb-Free Packages:
— AAT4296: 8-Pin SC70JW
— AAT4298: 10-Pin SC70JW and
12-Pin TSOPJW
EN/SET pin using AnalogicTech's Simple Serial
Control™ (S2Cwire™) interface. When EN/SET is
pulled to logic high, the device is enabled and con-
sumes 3µA of typical quiescent current. In the off

state, each output is pulled low to ground to affect
a logic low state for I/O expander or power switch-
ing applications; this circuit will act as a load dis-
charge function to rapidly turn off a load circuit.
