Quad/Dual, Low-Voltage, Bidirectional RF/Video Switches
_______________General Description
T h e MAX4565/MAX4566/MAX4567 are low-voltage T-switches designed for switching RF and video signals f r o m DC to 350MHz in 50 a n d 75 s y s t e m s . 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 sign a l s in either direction. On-resistance (60 m a x ) is matched between switches to 2.5 max and is flat (2 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 supp l i e s 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.

Note 1: Voltages on all other pins exceeding V+ or V- are clamped by internal diodes. Limit forward diode current to maximum current rating.
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.
