MAX4588CPI

Analog Switches - Special Purpose Overview

The MAX4588CPI is a low-voltage, dual 4-channel RF/video multiplexer designed for signal processing in 50Ω and 75Ω systems up to 180MHz. It features a flexible digital interface supporting parallel or SPI/MICROWIRE serial control. The device utilizes a 'T' switch configuration for high off-isolation and maintains an on-resistance of 60Ω max with 4Ω max matching. Operating from single +2.7V to +12V or dual ±2.7V to ±6V supplies, it offers TTL/CMOS compatibility at VL = +5V. The component is housed in a 28-pin narrow plastic DIP package and operates within a temperature range of 0°C to +70°C.

Analog Switches - Special Purpose Feature Summary

• High-frequency performance with 180MHz bandwidth and -74dB off-isolation
• Low on-resistance with excellent flatness across the specified signal range

Analog Switches - Special Purpose Applications

• RF switching
• Video signal routing
• Automatic test equipment
• Networking
• High-speed data acquisition

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix C for industrial temperature range (0°C to +70°C) against the E variant (-40°C to +85°C). Confirm the package type matches the required PCB footprint, as the CPI designation indicates a 28-pin narrow plastic DIP. Ensure supply voltages do not exceed absolute maximum ratings to prevent damage from internal ESD diode conduction.

Analog Switches - Special Purpose Selection Notes

Select this part for designs requiring dual independent 4-channel multiplexing with high isolation. Consider the 60Ω on-resistance limit when designing for low-loss paths. Verify that the logic supply voltage VL supports the required input levels, noting TTL/CMOS compatibility is guaranteed only at VL = +5V. Ensure power sequencing follows V+, V-, then VL to avoid latch-up or excessive current draw during startup.

Analog Switches - Special Purpose Part Context

The MAX4588CPI belongs to the MAX4588 family of low-voltage, high-isolation multiplexers. It shares core specifications with variants like the MAX4588EPI and MAX4588EWI, differing primarily in operating temperature range and physical package style. The CPI variant specifically denotes the industrial temperature grade and narrow DIP packaging option within the broader product line.

Analog Switches - Special Purpose Replacement Considerations

Direct pin-compatible replacements include other MAX4588 variants such as MAX4588EPI (industrial temp, DIP) or MAX4588EWI (extended temp, SOIC), provided the temperature range and package form factor meet design requirements.
