General Description

The MAX4529 is a low-voltage T-switch designed for
switching RF and video signals from DC to 300MHz in
50Ω and 75Ω systems. This switch is constructed in a
“T” configuration, ensuring excellent high-frequency off
isolation of -80dB at 10MHz.

The MAX4529 can handle Rail-to-Rail®analog signals
in either direction. On-resistance (70Ω max) is flat (0.5Ω
max) over the specified signal range, using ±5V sup­plies. The off leakage current is less than 1nA at +25°C
and 20nA at +85°C.

This CMOS switch can operate with dual power sup­plies ranging from ±2.7V to ±6V or a single supply
between +2.7V and +12V. All digital inputs have

0.8V/2.4V logic thresholds, ensuring both TTL- and
CMOS-logic compatibility when using ±5V or a single
+5V supply.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
