TPW4052-TR

Overview

The TPW4052-TR is a dual SP4T analog switch manufactured by 3PEAK, designed for analog and digital multiplexer or demultiplexer applications. It features three digital select inputs (S0, S1), eight independent I/Os (An, Bn), two common I/Os (A, B), and an active-low enable input (/E). The device operates on a single supply of 3 V to 12 V or dual supplies up to ±6 V. Key electrical parameters include a typical bandwidth of 200 MHz, turn-on time of 60 ns, and turn-off time of 50 ns. On-resistance varies with voltage: typically 300 Ω at 3 V, 60 Ω at 4.5 V, and 50 Ω at 9 V. It supports an operating temperature range from -40°C to 125°C.

Feature Summary

• Dual SP4T configuration providing flexible signal routing capabilities
• Break-before-make switching action prevents momentary shorting during channel transitions
• Enhanced CMOS process technology ensures low power dissipation while maintaining high switching speeds
• Input range extends to the supply rails, allowing full signal swing compatibility

Applications

• Industry control systems requiring reliable signal multiplexing
• Battery-powered systems benefiting from low quiescent current
• Audio signal routing applications demanding low distortion
• General-purpose instrumentation equipment

Procurement Notes

Verify the specific package variant when ordering, as the TPW4052-TR designation corresponds to the TSSOP16 package in the official order information. Confirm that the required quantity aligns with the standard tape and reel packaging of 3000 units per reel. Ensure that the application environment remains within the specified absolute maximum ratings to maintain device reliability and longevity.

Selection Notes

Select the TPW4052-TR when a dual 4-to-1 multiplexer architecture is required within a compact surface-mount footprint. Consider this component for designs needing rail-to-rail signal handling and fast switching speeds under varying supply voltages. Evaluate the thermal performance characteristics if the design operates near the upper limits of the specified temperature range or requires minimal heat dissipation.

Part Context

The TPW4052 belongs to the 3PEAK general-purpose analog switch family, which includes variants like the TPW4051 and TPW4053 offering different channel configurations. These devices share similar process technologies and performance profiles, such as 200 MHz bandwidth and low on-resistance. The TPW4052 specifically addresses applications requiring two independent 4-to-1 switching paths within a single integrated circuit.

Replacement Considerations

The datasheet does not list specific public substitute part numbers. Designers should evaluate industry-standard equivalents based on pin compatibility and electrical specifications, ensuring that any replacement meets the required voltage ranges and switching speed requirements.
