TPW4157-TR

Overview

The TPW4157-TR is a low-voltage Single Pole Double Throw (SPDT) analog switch manufactured by 3PEAK. It operates within a supply voltage range of 1.65 V to 5.5 V and features an ultra-low on-state resistance, typically 0.95 Ω at 4.5 V. The device supports a bandwidth of 100 MHz with fast switching times of 40 ns for turn-on and 15 ns for turn-off. It incorporates break-before-make switching logic and maintains very low quiescent current even when control voltages are lower than the supply rail. The component is available in SOT23-6 packaging and functions reliably across an extended temperature range from –40°C to 125°C.

Feature Summary

• Ultra-low on-state resistance ensures minimal signal attenuation in active paths.
• Break-before-make switching prevents signal shorting during channel transitions.
• Low quiescent current allows direct interfacing with processor GPIOs regardless of supply levels.
• Wide operating voltage range supports diverse low-power system architectures.

Applications

• Industry Control Systems
• Battery-Powered Systems
• Audio Signal Routing
• Portable Instruments and Mobile Devices

Procurement Notes

Verify that the ordering suffix matches the required package type, as the TPW4157-TR specifically denotes the SOT23-6 variant. Confirm the tape and reel quantity aligns with production requirements. Ensure the selected part meets the necessary moisture sensitivity level standards for your assembly process. Cross-reference the date code to verify manufacturing recency if storage conditions are critical.
