MAX4574EEI+T

Analog Switches - Special Purpose Overview

The MAX4574EEI+T is a serially controlled audio/video switch IC featuring two SPST and six SPDT switches. It operates on a single supply voltage ranging from +2.7V to +5.25V. The device utilizes a 3-wire SPI/QSPI/MICROWIRE-compatible interface for control. Key electrical parameters include a maximum on-resistance of 35Ω, -90dB audio off-isolation at 20kHz, and -50dB video off-isolation at 10MHz. It supports selectable soft switching mode for clickless audio operation and break-before-make timing. The component is housed in a 28-pin QSOP package and functions within an extended temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

Configurable soft-switching mode eliminates audible clicking during audio signal transitions
Integrated 3-wire serial interface compatible with standard digital protocols
High isolation performance ensures minimal signal leakage between channels

PC Multimedia Boards
Video Conferencing Systems

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix EEI corresponds to the required 28-pin QSOP package and extended temperature rating (-40°C to +85°C). Confirm that the 3-wire serial interface matches the system controller's communication protocol. Ensure the single-supply voltage requirements align with the design constraints before finalizing procurement.

Analog Switches - Special Purpose Selection Notes

Select this component when a combination of SPST and SPDT switching is required within a single package. The MAX4574 is distinct from the MAX4571/73 due to its 3-wire interface, whereas the MAX4571/72 use I2C. Consider the 35Ω on-resistance and bandwidth limitations when routing high-frequency video signals compared to lower-resistance alternatives.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4571–MAX4574 family of serially controlled switches manufactured by Analog Devices (Maxim Integrated). While sharing core switching technology, the MAX4574 differs from siblings like the MAX4571 by offering a mixed configuration of SPST and SPDT switches rather than only SPST units. It also utilizes a different serial interface protocol compared to the I2C-based MAX4572.
