Low-voltage, High-isolation, Dual 4-channel Rf/video Multiplexer

The 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.
