MAX4545EPP

Analog Switches - Special Purpose Overview

The MAX4545EPP is a quad, low-voltage, bidirectional RF/video switch manufactured by Analog Devices Inc./Maxim Integrated. It contains four normally open single-pole/single-throw (SPST) switches designed for switching signals from DC to 300MHz in 50Ω and 75Ω systems. 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 20Ω at ±5V, a -3dB bandwidth of 300MHz, and off isolation of -80dB at 10MHz. It features TTL/CMOS-compatible logic inputs and is housed in a 20-pin Plastic DIP package.

Analog Switches - Special Purpose Feature Summary

• T-switch construction ensures excellent high-frequency off isolation and crosstalk performance
• Rail-to-rail analog signal handling capability in either direction
• Low on-resistance with tight matching and flatness specifications over the signal range
• Compatible with both TTL and CMOS logic thresholds when using standard supply voltages

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 suffix EPP corresponds to the 20-pin Plastic DIP package and the C temperature range (0°C to +70°C) as defined in the official ordering information. Confirm RoHS compliance status through the manufacturer's documentation before procurement. Ensure the component source is an authorized distributor to guarantee authenticity and traceability.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring quad SPST switching with high bandwidth up to 300MHz. Consider the ±5V optimized performance for best linearity and speed. Evaluate the 20-pin DIP package constraints against board space requirements. Verify that the single-supply operation meets the necessary signal voltage ranges if bipolar supplies are not available.

Analog Switches - Special Purpose Part Context

The MAX4545EPP belongs to the MAX4545/MAX4546/MAX4547 family of low-voltage T-switches. While the MAX4546 offers dual SPST configurations and the MAX4547 provides dual SPDT switches, the MAX4545 specifically integrates four independent SPST channels. This family shares common architectural features such as the T-switch topology and low-voltage operation capabilities.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes within the same family include the MAX4545CPP and MAX4545CWP, which offer identical functionality in different packages. Cross-family replacements like the MAX4546 or MAX4547 provide similar switching characteristics but differ in channel configuration.
