General Description

The MAX4529 is a low-voltage T-switch designed for

switching RF and video signals from DC to 300MHz in

50

Ω and 75Ω systems. This switch is constructed in a

“T” configuration, ensuring excellent high-frequency off

isolation of -80dB at 10MHz.

in either direction. On-resistance (70

Ω max) is flat (0.5Ω

max) over the specified signal range, using ±5V sup-

plies. The off leakage current is less than 1nA at +25°C

and 20nA at +85°C.

This CMOS switch can operate with dual power sup-

plies 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.
