For small orders, phone 1-800-835-8769.
General Description
The MAX4588 low-voltage, dual 4-channel multiplexer
is designed for RF and video signal processing at frequencies up to 180MHz in 50Ω and 75Ω systems. A
flexible digital interface allows control of on-chip functions 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 offleakage current is under 1nA at TA= +25°C, and less
than 10nA at TA= +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 compatibility. The MAX4588 is available in 28-pin narrow
DIP, wide SO, and space-saving SSOP packages.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
