MAX4588CWI+T

Analog Switches - Special Purpose Overview

The MAX4588CWI+T is a low-voltage, dual 4-channel RF/video multiplexer designed for signal processing in 50 Ω and 75 Ω systems up to 180MHz. It features a flexible digital interface supporting parallel or SPI/MICROWIRE serial control. The device operates from single +2.7V to +12V or dual ±2.7V to ±6V supplies. Key electrical parameters include a maximum on-resistance of 60Ω with ±5V supplies, an on-resistance match of 4Ω max, and on-resistance flatness of 2Ω max. It provides -74dB off-isolation at 10MHz and -70dB channel-to-channel crosstalk up to 10MHz. The component is housed in a 28-pin Wide SO package.

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature range. The 'C' indicates commercial temperature range (0°C to +70°C), while 'E' denotes extended range (-40°C to +85°C). The 'W' specifies the Wide SO package. Confirm RoHS compliance status through official manufacturer documentation prior to procurement.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring dual independent multiplexing channels with high isolation. Ensure the supply voltage matches the required analog signal range, noting that performance degrades significantly below ±5V. Verify that the control interface logic levels are compatible with the system's VL supply voltage. Consider thermal dissipation requirements based on the chosen package and ambient temperature conditions.
