The MAX4588 low-voltage, dual 4-channel multiplexer is designed for RF and video signal processing at frequencies up to 180MHz in 50O and 75O 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 60O max, with an on-resistance match across all channels of 4O max. Additionally, on-resistance is flat across the specified signal range (2O max). The off- leakage 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.
