TS3DDR3812RUAR

Analog Switches - Special Purpose Overview

The TS3DDR3812RUAR is a high-speed multiplexer switch IC from Texas Instruments, featuring 12 channels configured as 1:2 MUX/DEMUX switches. It operates within a supply voltage range of 3 V to 3.6 V and utilizes a WQFN-42 package for surface mount installation. Key electrical parameters include a maximum on-resistance of 12 Ohms, a typical off-isolation of -42 dB, and a bandwidth of 1.675 GHz. The device supports a maximum operating frequency with a propagation delay of 40 ps, while turn-on and turn-off times are limited to 7 ns and 5 ns respectively. It functions reliably across an industrial temperature range from -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix RUAR corresponds to the required WQFN-42 package and reel packaging configuration. Confirm that the 3.3 V operating voltage aligns with the target system design before procurement. Ensure compatibility with the specified industrial temperature range of -40°C to +85°C for the intended application environment.

Analog Switches - Special Purpose Selection Notes

Select this component when a dense array of 12 high-speed SPDT switches is required in a compact footprint. The 12 Ohm on-resistance and -42 dB off-isolation make it suitable for maintaining signal integrity in high-frequency applications. Consider the WQFN-42 package constraints regarding thermal dissipation and PCB layout requirements during the design phase.
