MAX4567EEE

Analog Switches - Special Purpose Overview

The MAX4567EEE is a dual, low-voltage, bidirectional RF/Video Switch IC manufactured by Analog Devices Inc./Maxim Integrated. It contains two single-pole/double-throw (SPDT) switches constructed in a T-switch configuration to ensure high-frequency isolation. The device operates with dual power supplies ranging from ±2.7V to ±6V or a single supply between +2.7V and +12V. Key electrical parameters include a maximum on-resistance of 60Ω at ±5V, a -3dB bandwidth of 350MHz, and off-isolation of -83dB at 10MHz. It features TTL/CMOS-compatible logic inputs and operates within a temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• T-switch architecture providing superior high-frequency signal isolation and crosstalk reduction
• Bidirectional analog signal handling capable of rail-to-rail operation
• Logic-level translation ensuring compatibility with both TTL and CMOS standards

Analog Switches - Special Purpose Applications

• RF switching systems
• Video signal routing and multiplexing
• High-speed data acquisition circuits
• Test and measurement equipment
• Automated test equipment (ATE)

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'EEE' corresponds to the industrial temperature grade (-40°C to +85°C) and the 16-pin QSOP package. Confirm RoHS compliance status for the exact part number variant before procurement. Ensure the ordering documentation matches the manufacturer's current datasheet revision to avoid discrepancies in pinout or electrical characteristics.

Analog Switches - Special Purpose Selection Notes

Select the MAX4567EEE when dual SPDT switching functionality is required for RF or video applications up to 350MHz. This component is suitable for designs needing low on-resistance matching and flatness. Consider the ±5V optimized performance for best AC characteristics; note that single-supply or lower voltage operation will increase on-resistance and switching times.

Analog Switches - Special Purpose Part Context

The MAX4567EEE belongs to the MAX4565/MAX4566/MAX4567 family of quad/dual low-voltage bidirectional RF/video switches. While the MAX4565 offers four SPST switches and the MAX4566 provides dual SPST switches, the MAX4567 specifically integrates two SPDT switches. All variants share the same T-switch topology and general electrical characteristics.

Analog Switches - Special Purpose Replacement Considerations

Direct functional substitutes within the same family include the MAX4565EEE and MAX4566EEE, though channel count and type differ. For cross-family replacements, verify that the alternative switch maintains comparable bandwidth, on-resistance, and package dimensions.
