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.
