MAX4547EEE

Analog Switches - Special Purpose Overview

The MAX4547EEE is a dual single-pole/double-throw (SPDT) low-voltage bidirectional RF/video switch. It operates from dual supplies of ±2.7V to ±6V or a single supply of +2.7V to +12V. The device features a maximum on-resistance of 20Ω, a -3dB bandwidth of 300MHz, and typical off isolation of -82dB at 10MHz. Turn-on time is typically 150ns, while turn-off time is typically 100ns. It is housed in a 16-pin QSOP package and supports an operating temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Bidirectional signal switching with T-switch construction for high-frequency performance
• TTL and CMOS logic compatibility with defined input thresholds
• Break-before-make switching action to prevent signal shorting

Analog Switches - Special Purpose Applications

• RF switching in communication systems
• Video signal routing and multiplexing
• High-speed data acquisition systems
• 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 surface-mount package. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications.

Analog Switches - Special Purpose Selection Notes

Select this component when dual SPDT switching is required within a low-voltage environment. Ensure the application utilizes ±5V supplies to achieve optimal on-resistance matching and flatness. Verify that the board layout accommodates separate ground pins for each switch to maintain high-frequency isolation.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4545/MAX4546/MAX4547 family of low-voltage analog switches. While the MAX4545 offers four SPST switches and the MAX4546 provides two SPST switches, the MAX4547 specifically integrates two SPDT switches. All variants share similar electrical characteristics and pinout structures.

Analog Switches - Special Purpose Replacement Considerations

MAX4547CEE+ is a direct functional substitute offering identical electrical specifications but with a commercial temperature range (0°C to +70°C). Both parts utilize the same 16-QSOP package and pin configuration.
