TC7W66FK,LF

Overview

The TC7W66FK,LF is a dual bilateral switch IC from Toshiba Semiconductor and Storage, housed in an US8 package. It operates on a supply voltage (VCC) ranging from 2 V to 12 V and supports an operating temperature range of -40 °C to +85 °C. The device features a typical propagation delay (tpd) of 7 ns at 5 V, with a maximum quiescent supply current (ICC) of 1 μA at 25 °C. Typical ON resistance (RON) is 50 Ω at 9 V, and total harmonic distortion (THD) is 0.05% at 5 V.

Feature Summary

• High-speed switching capability with low propagation delay for digital and analog signal control
• Low power dissipation design ensuring minimal quiescent current consumption
• High noise immunity providing stable operation across varying supply voltages
• Integrated protection circuits against static discharge and transient excess voltage

Applications

• Digital and analog signal routing
• Signal multiplexing applications
• Data acquisition systems

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the FK suffix denotes the US8 package configuration. Confirm RoHS compliance status through official Toshiba documentation before procurement. Ensure the component meets the intended environmental operating temperature requirements during selection.

Selection Notes

Select this component when a dual bilateral switch is required for both digital and analog signal paths within a single package. Consider the 2 V to 12 V supply range and the specific ON resistance characteristics relative to the load current. Verify that the US8 package dimensions align with the PCB layout constraints.

Part Context

This part belongs to the TC7W series of CMOS digital integrated circuits manufactured by Toshiba Semiconductor and Storage. It serves as a high-speed bilateral switch designed for applications requiring low power consumption and high linearity. The device is functionally compatible with other similar bilateral switches in the industry.

Replacement Considerations

The datasheet indicates pin and function compatibility with the TC4W66. Verify electrical specifications and package dimensions match the original design requirements before substitution.

FAQ

What is the difference between the TC7W66FU and TC7W66FK packages?

The TC7W66FU uses an SM8 package, while the TC7W66FK utilizes a US8 package. Both contain the same internal circuitry but differ in physical footprint and weight.

How does the control input affect the switch state?

The switch turns ON when the control input (C) is high and turns OFF when the control input is low.
