MAX4567CEE+

Analog Switches - Special Purpose Overview

The MAX4567CEE+ is a dual single-pole/double-throw (SPDT) bidirectional RF/video switch manufactured by Analog Devices. It operates from dual supplies of ±2.7V to ±6V or a single supply of +2.7V to +12V. Key electrical parameters include a maximum on-resistance of 60Ω, a -3dB bandwidth of 350MHz, and off-isolation of -83dB at 10MHz. The device supports turn-on times up to 150ns and turn-off times up to 100ns. It is housed in a 16-pin QSOP package and functions within an operating temperature range of 0°C to +70°C.

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'CEE+' against official manufacturer documentation to confirm the commercial temperature grade and lead-free status. Ensure the 16-pin QSOP package matches the design requirements. Cross-reference the ordering information table in the datasheet to validate availability and exact part identification before procurement.

Analog Switches - Special Purpose Selection Notes

Select this component when dual SPDT switching is required for signals up to 350MHz. Verify that the ±5V supply optimization aligns with the system power rails, as performance degrades at lower voltages. Ensure the board layout accommodates separate ground pins for each switch to maintain high-frequency isolation characteristics.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4565/MAX4566/MAX4567 family of low-voltage CMOS analog switches. While the MAX4565 offers four SPST channels and the MAX4566 provides two dual SPST switches, the MAX4567 specifically integrates two SPDT switches. All variants share similar T-switch construction and low-power consumption characteristics.

Analog Switches - Special Purpose FAQ

How does the T-switch configuration improve performance?

The T-switch uses two series CMOS switches with a third N-channel switch shunting capacitively-coupled signals to ground when off, ensuring superior high-frequency isolation.

What are the logic input threshold levels?

The inputs have 0.8V/2.4V logic thresholds, ensuring compatibility with both TTL and CMOS logic when using ±5V or a single +5V supply.

Can the switches handle rail-to-rail analog signals?

Yes, the switches can handle rail-to-rail analog signals in either direction across the specified supply voltage ranges.
