MAX4529 19-1262 Rev 1 5/01 Low-Voltage, Bidirectional RF/Video Switch General Description Features The MAX4529 is a low-voltage T-switch designed for High 50 Off Isolation: -80dB at 10MHz switching RF and video signals from DC to 300MHz in DC to 300MHz -3dB Signal Bandwidth 50 and 75 systems. This switch is constructed in a T configuration, ensuring excellent high-frequency off 70 Signal Paths with 5V Supplies isolation of -80dB at 10MHz. 10 Signal-Path Flatness with 5V Supplies The MAX4529 can handle Rail-to-Rail analog signals 2.7V to 6V Dual Supplies in either direction. On-resistance (70 max) is flat (0.5 +2.7V to +12V Single Supply max) over the specified signal range, using 5V sup- plies. The off leakage current is less than 1nA at +25C Low Power Consumption: <1W and 20nA at +85C. Rail-to-Rail Bidirectional Signal Handling This CMOS switch can operate with dual power sup- >2kV ESD Protection per Method 3015.7 plies ranging from 2.7V to 6V or a single supply between +2.7V and +12V. All digital inputs have TTL/CMOS-Compatible Inputs with 0.8V/2.4V logic thresholds, ensuring both TTL- and Single +5V or 5V CMOS-logic compatibility when using 5V or a single +5V supply.

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.
