_______________General Description

The MAX4565/MAX4566/MAX4567 are low-voltage T-switches designed for switching RF and video signals from DC to 350MHz in 50Ω and 75Ω systems. The MAX4565 contains four normally open single-pole/singlethrow (SPST) switches. The MAX4566 contains two dual SPST switches (one normally open, one normally closed.) The MAX4567 contains two single-pole/double-throw (SPDT) switches.

Each switch is constructed in a “T” configuration, ensuring excellent high-frequency off isolation and crosstalk of

-83dB at 10MHz. They can handle Rail-to-Rail

analog signals in either direction. On-resistance (60Ω max) is matched between switches to 2.5Ω max and is flat (2Ω max) over the specified signal range, using ±5V supplies. The off leakage current is less than 5nA at +25°C and 50nA at +85°C.

These CMOS switches 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.
