MAX4545CWP-T

Analog Switches - Special Purpose Overview

The MAX4545CWP-T is a quad bidirectional RF/video switch IC manufactured by Analog Devices Inc./Maxim Integrated. It features four independent SPST switches in a 20-SOIC package. The device operates on a single supply voltage ranging from 2.7 V to 12 V, or dual supplies of ±2.7 V to ±6 V. Key electrical parameters include a -3 dB bandwidth of 300 MHz, maximum on-resistance of 20 Ohms, and typical off-isolation of -80 dB. Switching times are specified with a maximum turn-on time of 120 ns and turn-off time of 200 ns. Power dissipation is rated at 800 mW, and the operating temperature range extends from 0°C to +70°C.

Analog Switches - Special Purpose Feature Summary

• Bidirectional signal path capability suitable for RF and video applications
• T-structure analog switch architecture providing high isolation characteristics
• Quad configuration integrating four independent SPST channels

Analog Switches - Special Purpose Applications

• Industrial television monitoring systems
• Multi-channel large-scale surveillance setups
• Video switching arrays requiring high bandwidth

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix against official documentation, as availability varies between tape-and-reel and tube packaging formats. Confirm RoHS compliance status for the exact variant, as some listings indicate lead-free construction while others may differ. Cross-reference the manufacturer part number with distributor codes to ensure correct component identification before ordering.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring high-frequency video signal routing with low distortion. Ensure the system power supply aligns with the 2.7 V to 12 V operational range. Verify that the 20 Ohm on-resistance meets the signal integrity requirements for the specific application bandwidth needs.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4545 series of CMOS analog switches designed for high-performance video and RF switching. It is distinct from multiplexer variants like the MAX4539 due to its SPST configuration rather than multi-input selection. The device utilizes a T-switch structure optimized for minimal signal degradation in passive switching environments.
