Quad/Dual, Low-Voltage,
Bidirectional RF/Video Switches
_______________General Description ____________________________Features
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/single-
throw (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 sig-
nals 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 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 com-
patibility when using ±5V or a single +5V supply.
