MAX4567CPE

Analog Switches - Special Purpose Overview

The MAX4567CPE 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 housed in a 16-pin Plastic DIP package. 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. The operating temperature range for the 'C' suffix variant is 0°C to +70°C.

Analog Switches - Special Purpose Feature Summary

• Bidirectional signal switching capability for RF and video applications
• T-switch construction ensuring high-frequency off isolation and low crosstalk
• TTL and CMOS logic input compatibility with single +5V or ±5V supplies

Analog Switches - Special Purpose Applications

• RF Switching
• Video Signal Routing
• High-Speed Data Acquisition
• Test Equipment
• ATE Equipment

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. The 'CPE' designation indicates a Plastic DIP package with a commercial temperature range. Ensure that the component source provides valid traceability and authenticity certificates, as counterfeit components may exhibit degraded high-frequency performance or incorrect logic thresholds.

Analog Switches - Special Purpose Selection Notes

Select this component when a dual SPDT configuration is required for low-voltage systems. Verify that the application environment remains within the 0°C to +70°C operating range. Confirm that the system impedance matches the 50Ω or 75Ω design targets to achieve specified insertion loss and isolation levels. Ensure adequate bypass capacitance is placed near the supply pins to maintain stability.

Analog Switches - Special Purpose Part Context

The MAX4567 is part of 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 similar T-switch architecture and low-voltage operational characteristics.

Analog Switches - Special Purpose Replacement Considerations

Direct functional substitutes within the same family include the MAX4565EEE+T and MAX4566EEE+T, though pin configurations and switch counts differ. Cross-family replacements require verification of package dimensions, pinout compatibility, and electrical parameter alignment with the original design requirements.

Analog Switches - Special Purpose FAQ

What is the maximum differential voltage allowed between V+ and V-?

The absolute maximum differential voltage between V+ and V- is 13.0V. Exceeding this limit, even briefly due to overshoot or noise spikes, may cause permanent damage to the device.

How does single-supply operation affect performance compared to dual-supply?

Single-supply operation degrades switching speed, increases on-resistance, reduces off-isolation, and increases distortion compared to the optimized ±5V dual-supply operation. AC signals are also limited to -0.3V relative to ground.

Why are separate GND_ pins provided for each switch?

Separate GND_ pins are not internally connected to improve high-frequency performance and provide flexibility. They allow individual grounding strategies but must be connected to a solid ground plane to ensure optimal isolation and crosstalk performance.
