Low-Voltage, High-Isolation,
Dual 2-Channel RF/Video Multiplexer
General Description
The MAX4589 low-voltage, dual 2-channel multiplexer is
designed for RF and video signal processing at frequen-
cies up to 200MHz in 50Ω and 75Ω systems. On-chip
functions are controlled through either a parallel interface
or an SPI™/QSPI™/MICROWIRE™ serial interface.
Each channel of the MAX4589 is designed using a “T”
switch configuration, ensuring excellent high-frequency
off-isolation. The MAX4589 has low on-resistance of
60Ω max, with an on-resistance match across all chan-
nels of 4Ω max. Additionally, on-resistance is flat
across the specified signal range (2Ω max). The off-
leakage current is under 1nA at T_A = +25°C, and less
than 10nA at T_A = +85°C.
The MAX4589 operates from single +2.7V to +12V or
dual ±2.7V to ±6V supplies. When operating with a
positive supply of +5V, the inputs maintain TTL/CMOS-
level compatibility. The MAX4589 is available in 20-pin
DIP, wide SO, and SSOP packages.
