MAX4589 19-1424 Rev 0 1/99 Low-Voltage, High-Isolation, Dual 2-Channel RF/Video Multiplexer General Description Features The MAX4589 low-voltage, dual 2-channel multiplexer is Low Insertion Loss: < -2.5dB up to 100MHz designed for RF and video signal processing at frequen- High Off-Isolation: -74dB at 10MHz cies up to 200MHz in 50W and 75W systems. On-chip functions are controlled through either a parallel interface Low Crosstalk: < -70dB up to 10MHz or an SPI/QSPI/MICROWIRE serial interface. 20MHz -0.1dB Signal Bandwidth Each channel of the MAX4589 is designed using a T switch configuration, ensuring excellent high-frequency 200MHz -3dB Signal Bandwidth off-isolation. The MAX4589 has low on-resistance of 60W (max) On-Resistance with 5V Supplies 60W max, with an on-resistance match across all chan- nels of 4W max. Additionally, on-resistance is flat 4W (max) On-Resistance Matching with 5V across the specified signal range (2W max). The off- Supplies leakage current is under 1nA at T = +25C, and less A 2W (max) On-Resistance Flatness with 5V than 10nA at T = +85C. A Supplies The MAX4589 operates from single +2.7V to +12V or dual 2.7V to 6V supplies. When operating with a +2.7V to +12V Single-Supply Operation positive supply of +5V, the inputs maintain TTL/CMOS- 2.7V to 6V Dual-Supply Operation level compatibility. The MAX4589 is available in 20-pin DIP, wide SO, and 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.
