TPW4066-TR

Overview

The TPW4066-TR is a quad single-pole single-throw (SPST) analog switch manufactured by 3PEAK, designed for analog and digital multiplexer or demultiplexer applications. It features four independent switches controlled by dedicated digital select inputs (S1–S4). The device supports supply voltages of 3.3 V, 5 V, and 10 V, with an operating range from 3 V to 12 V. Key electrical parameters include a typical bandwidth of 200 MHz at 5 V/10 V supplies and fast switching times of tON = 60 ns and tOFF = 50 ns. On-state resistance varies with voltage: typically 300 Ω at 3 V, 60 Ω at 4.5 V, and 50 Ω at 9 V. It operates within a temperature range of –40°C to 125°C and utilizes TSSOP14 packaging.

Feature Summary

• Break-before-make switching logic prevents signal overlap during channel transitions.
• Input signals extend fully to the positive and negative supply rails.
• Enhanced process technology ensures low power dissipation and high switching speed.
• Capable of functioning as either multiplexers or demultiplexers.

Applications

• Industry control systems
• Battery-powered systems
• Audio signal routing
• Instrumentation

Procurement Notes

Verify the specific package variant when ordering, as the TPW4066-TR designation corresponds to the TSSOP14 package in the official order information. Confirm that the required quantity aligns with the standard tape and reel count of 3,000 units per manufacturer specification. Ensure design compatibility with the –40°C to 125°C operating temperature range and validate ESD protection requirements against the specified HBM and CDM levels before finalizing procurement.

Selection Notes

Select the TPW4066-TR when a quad SPST configuration is required for signal routing in space-constrained designs utilizing TSSOP14 packages. Consider this component for applications demanding high bandwidth up to 200 MHz and low on-state resistance at higher supply voltages. Evaluate the trade-off between the 300 Ω resistance at 3 V operation versus lower resistance at 5 V or 10 V if signal integrity under varying load conditions is critical to the system performance.

Part Context

The TPW4066 belongs to the 3PEAK analog switch family, which includes multiplexers like the TPW4051 and TPW4052. Unlike these multi-channel selectors, the TPW4066 provides four independent SPST channels, offering greater flexibility for parallel signal paths. It shares similar performance characteristics, such as 200 MHz bandwidth and 12 V maximum supply rating, with other devices in the series but distinguishes itself through its specific pinout and independent control architecture.

FAQ

What is the maximum supply voltage supported by the TPW4066?

The absolute maximum supply voltage (VCC to GND) is 13 V, with recommended operating conditions supporting up to 12 V.

How does the on-state resistance change with supply voltage?

The typical on-state resistance decreases as supply voltage increases: it is approximately 300 Ω at 3 V, 60 Ω at 4.5 V, and 50 Ω at 9 V.

Does the TPW4066 support rail-to-rail input signals?

Yes, the device input range extends to the supplies, allowing it to operate effectively with signals spanning the full supply voltage range.
