Overview
The TPW4053-SR is a three single-pole dual-throw (SPDT) analog switch designed for multiplexer and demultiplexer applications. It operates on a single supply of 3 V to 12 V or dual supplies of ±5 V, with an operating temperature range of –40°C to 125°C. The device features low on-state resistance, typically 50 Ω at ±4.5 V and 60 Ω at 4.5 V. It provides a bandwidth of 200 MHz and fast switching times of 60 ns turn-on and 50 ns turn-off. The component includes break-before-make switching action and is housed in an SOP16 package.
Feature Summary
- Three independent SPDT switches controlled by digital select inputs S0, S1, and S2.
- Break-before-make switching action prevents momentary shorting during channel transitions.
- Input voltage range extends to the power supply rails for flexible signal handling.
- Active-low enable input (E) allows global shutdown of all channels.
Applications
- Industry control systems
- Battery-powered systems
- Audio signal routing
- Instrumentation
Procurement Notes
Verify the ordering suffix 'SR' corresponds to the SOP16 package configuration as specified in the manufacturer's order information table. Confirm that the required quantity aligns with the standard tape and reel packaging quantity of 2500 units per reel. Ensure the selected variant meets the specific thermal and electrical requirements for the target application environment.
Selection Notes
Select this component when a triple SPDT analog switch is required for signal routing within industrial or instrumentation environments. The device supports both single and dual supply configurations, making it suitable for various voltage domains. Consider the 200 MHz bandwidth and low distortion characteristics for high-fidelity audio or data acquisition applications requiring precise signal path management.
Part Context
The TPW4053 belongs to the TPW405x series of analog switches from 3PEAK, which also includes the TPW4051 (8:1) and TPW4052 (4:1 x 2). These devices share similar performance metrics such as 200 MHz bandwidth and low on-resistance but differ in channel count and configuration. The series is designed for general-purpose analog signal switching in compact packages.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult the manufacturer's official resources for recommended replacements or pin-compatible alternatives if sourcing constraints arise.
FAQ
What is the function of the Enable (E) pin?
The Enable (E) pin is active-low. When E is HIGH, all switches are turned off regardless of the state of the select inputs S0, S1, and S2.
Does the TPW4053 support simultaneous make-before-break switching?
No, the device is designed with break-before-make switching action to prevent momentary shorting between channels during switching transitions.
What is the maximum supply voltage difference allowed?
The absolute maximum rating for the supply voltage difference (VCC - VEE) is 13 V.
