TPW4051-SR

Overview

The TPW4051-SR is a single-pole octal-throw (SP8T) analog switch designed for general-purpose multiplexer and demultiplexer applications. It features three digital select inputs, eight independent I/O channels, and an active-low enable input. The device supports supply voltages of 3.3 V, 5 V, 10 V, and ±5 V, with a total supply range of 3 V to 12 V. Typical on-state resistance is 60 Ω at 4.5 V, 50 Ω at ±4.5 V or 9 V, and 300 Ω at 3 V. It offers a bandwidth of 200 MHz, turn-on time of 60 ns, and turn-off time of 50 ns. Operating temperature ranges from –40°C to 125°C.

Feature Summary

Break-before-make switching action prevents momentary shorting during channel transitions.
Input signal range extends fully to the power supply rails.
Enhanced process technology provides low power dissipation and high switching speed.
Active-low digital enable input allows easy system control.

Applications

Industry Control Systems
Battery-Powered Systems
Audio Signal Routing
Instrumentation

Procurement Notes

Verify the specific package type required, as the TPW4051-SR designation corresponds to the SOP16 package in official documentation. Confirm that the ordering suffix aligns with the desired tape and reel quantity and RoHS compliance status before finalizing procurement orders.

Selection Notes

Select this component when an 8:1 multiplexing configuration is required within a 12 V system. Ensure the application voltage falls within the 3 V to 12 V operating range. Consider the 200 MHz bandwidth and low leakage characteristics if high-frequency signal integrity is critical for the design.

Part Context

The TPW4051 belongs to the 3PEAK TPW40xx series of general-purpose analog switches. This family includes variants with different channel counts, such as the TPW4052 (dual 4:1) and TPW4053 (triple 2:1), offering flexible routing options for various signal processing architectures.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by comparing pin configurations, electrical specifications, and thermal requirements against alternative components.

FAQ

What is the function of the Enable (E) pin?

The Enable pin is active-low. When held high, the switch is turned off, disconnecting all channels regardless of the state of the select inputs S0, S1, and S2.

How does the break-before-make feature benefit the circuit?

This feature ensures that the common output disconnects from the current channel before connecting to the new one, preventing momentary shorting between channels during switching operations.
