产品概述

The MAX4589 low-voltage, dual 2-channel multiplexer is designed for RF and video signal processing at frequencies up to 200MHz in 50Ω and 75Ω systems. On-chip functions are controlled through either a parallel interface or an SPI™/QSPI™/MICROWIRE™ serial interface.

Each channel of the MAX4589 is designed using a "T" switch configuration, ensuring excellent high-frequency off-isolation. The MAX4589 has low on-resistance of 60Ω max, with an on-resistance match across all channels of 4Ω max. Additionally, on-resistance is flat across the specified signal range (2Ω max). The off-leakage current is under 1nA at TA = +25°C, and less than 10nA at TA = +85°C.

The MAX4589 operates from single +2.7V to +12V or dual ±2.7V to ±6V supplies. When operating with a positive supply of +5V, the inputs maintain TTL/CMOS- level compatibility. The MAX4589 is available in 20-pin DIP, wide SO, and SSOP packages.
