MAX4588 19-1425 Rev 0 1/99 Low-Voltage, High-Isolation, Dual 4-Channel RF/Video Multiplexer General Description Features The MAX4588 low-voltage, dual 4-channel multiplexer Low Insertion Loss: -2.5dB up to 100MHz is designed for RF and video signal processing at fre- High Off-Isolation: -74dB at 10MHz quencies up to 180MHz in 50 and 75 systems. A flexible digital interface allows control of on-chip func- Low Crosstalk: -70dB up to 10MHz tions through either a parallel interface or an SPI/ 16MHz -0.1dB Signal Bandwidth MICROWIRE serial port. Each channel of the MAX4588 is designed using a T 180MHz -3dB Signal Bandwidth switch configuration, ensuring excellent high-frequency 60 (max) On-Resistance with 5V Supplies off-isolation. The MAX4588 has low on-resistance of 60 max, with an on-resistance match across all chan- 4 (max) On-Resistance Matching with 5V nels of 4 max. Additionally, on-resistance is flat Supplies across the specified signal range (2 max). The off- 2 (max) On-Resistance Flatness with 5V leakage current is under 1nA at T = +25C, and less A Supplies than 10nA at T = +85C. A +2.7V to +12V Single Supply The MAX4588 operates from single +2.7V to +12V or dual 2.7V to 6V supplies. When operating with a +5V 2.7V to 6V Dual Supplies supply, the inputs maintain TTL- and CMOS-level com- Low Power Consumption: <20W patibility. The MAX4588 is available in 28-pin narrow DIP, wide SO, and space-saving SSOP packages.

Limit forward diode current to maximum current rating. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
