General Description
The MAX4588 low-voltage, dual 4-channel multiplexer is designed for RF and video signal processing at frequencies up to 180MHz in 50Ωand 75Ωsystems. 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 channels of 4Ωmax. Additionally, on-resistance is flat across the specified signal range (2Ωmax). The off leakage current is under 1nA at TA= +25°C, and less
than 10nA at TA= +85°C.
