MAX4588CAI+

The MAX4588CAI+ from Maxim Integrated Products is a low voltage, high-isolation, dual 4-channel RF/video multiplexer in 28 pin SSOP package. The low voltage, dual 4-channel multiplexer is designed for RF and video signal processing at frequencies up to 180MHz in 50 ohm and 75ohm 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 60 ohm max with an on-resistance match across all channels of 4ohm max. Additionally, on-resistance is flat across the specified signal range (2ohm max). The off leakage current is under 1nA at TA = +25°C and less than 10nA at TA = +85°C. It is used in RF switching automatic test equipment, video signal routing networking and high-speed data acquisition.
