Low-Voltage, High-Isolation,
Dual 4-Channel RF/Video Multiplexer
General Description
The MAX4588 low-voltage, dual 4-channel multiplexer
is designed for RF and video signal processing at fre-
quencies up to 180MHz in 50Ω and 75Ω systems. A
flexible digital interface allows control of on-chip func-
tions through either a parallel interface or an SPI™/
MICROWIRE™ serial port.
Each channel of the MAX4588 is designed using a “T”
switch configuration, ensuring excellent high-frequency
off-isolation. The MAX4588 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 MAX4588 operates from single +2.7V to +12V or
dual ±2.7V to ±6V supplies. When operating with a +5V
supply, the inputs maintain TTL- and CMOS-level com-
patibility. The MAX4588 is available in 28-pin narrow
DIP, wide SO, and space-saving SSOP packages.
