Fe a t u re s
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.
♦ Low Insertion Loss: < -2.5dB up to 100MHz
♦ High Off-Isolation: -74dB at 10MHz
♦ Low Crosstalk: < -70dB up to 10MHz
♦ 20MHz -0.1dB Signal Bandwidth
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-
ne ls of 4Ω ma x. Ad d itiona lly, on-re s is ta nc e is fla t
across the specified signal range (2Ω max). The off-

Supplies
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.
