MAX4529 Datasheet, PDF (1/12 Pages) Maxim Integrated Products – Low-Voltage, Bidirectional RF/Video Switch

19-1262; Rev 0; 3/98
Low-Voltage, Bidirectional
RF/Video Switch
General Description
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 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.
