MAX4545CAP+T

Analog Switches - Special Purpose Overview

The MAX4545CAP+T is a quad, low-voltage, bidirectional RF/video switch designed for switching signals from DC to 300MHz in 50Ω and 75Ω systems. It contains four normally open single-pole/single-throw (SPST) switches constructed in a T-switch configuration. 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, an off-isolation of -80dB at 10MHz, and a signal bandwidth of 300MHz. The component features TTL/CMOS-compatible logic inputs and provides 2kV ESD protection per Method 3015.7.

Analog Switches - Special Purpose Feature Summary

• Bidirectional analog signal handling with rail-to-rail capability
• High-frequency isolation and crosstalk performance optimized for RF applications
• Low on-resistance with high matching and flatness characteristics
• Logic-level translation ensuring compatibility with standard digital interfaces

Analog Switches - Special Purpose Applications

• RF switching in communication systems
• Video signal routing and multiplexing
• High-speed data acquisition systems
• Automated test equipment (ATE)
• Networking infrastructure components

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range of 0°C to +70°C. Confirm the '+T' designation corresponds to tape-and-reel packaging if required by assembly processes. Ensure the ordering code matches the exact package type needed for the target PCB layout.

Analog Switches - Special Purpose Selection Notes

Select this component when a quad SPST configuration is required for video or RF paths up to 300MHz. Consider the MAX4546 or MAX4547 if dual SPST or SPDT topologies are preferred. Evaluate supply voltage constraints, as performance degrades significantly below ±5V operation.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4545/MAX4546/MAX4547 family of CMOS analog switches manufactured by Analog Devices/Maxim Integrated. The family shares identical internal architecture but differs in switch topology, offering flexibility for various multiplexer and crossbar switch designs within low-voltage systems.
