PRELIMINARY DATASHEET
0.5Ω LOW VOLTAGE, QUAD SPDT ANALOG SWITCH
Description
The IDTAS3699A quad single-pole/double-throw (SPDT)
analog switch operates from a single +1.65 V to +4.3 V
supply and responds to TTL control input levels. Additional
features include fast switching speed and
break-before-make delay time. This product is available in
3x3mm and 2.5x2.5mm 16-pin QFN packages.

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the IDTAS3699A. These ratings, which
are standard values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at
these or any other conditions above those indicated in the operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical
parameters are guaranteed only over the recommended operating temperature range. All voltages referenced to
ground.
