Low-voltage, High-isolation, Dual 4-channel Rf/video MultiplexerThe MAX4588 low-voltage, dual 4-channel multiplexer
is designed for RF and Video signal processing at fre-
quencies up to 180MHz in 50 and 75 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
60 max, with an on-resistance match across all chan-
nels of 4 max. Additionally, on-resistance is flat
across the specified signal range (2 max). The off-
leakage current is under 1nA at TA = +25C, and less
than 10nA at TA = +85C.
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. By Maxim Integrated Products
