TC7W66FU,LF

Overview

The TC7W66FU,LF is a dual bilateral switch manufactured by Toshiba Semiconductor and Storage using silicon gate CMOS technology. It features four independent high-speed switches capable of controlling digital or analog signals while maintaining low power dissipation. The device operates within a supply voltage range of 2 V to 12 V and an operating temperature range of -40°C to +85°C. Key electrical parameters include a typical propagation delay (tpd) of 7 ns at 5 V, a maximum quiescent supply current (ICC) of 1 μA at 25°C, and a typical ON resistance (RON) of 50 Ω at 9 V. The package is SM8.

Feature Summary

• High speed operation with typical propagation delay of 7 ns
• Low power dissipation with maximum quiescent current of 1 μA
• High noise immunity with minimum noise margins of 28% VCC

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the datasheet indicates compatibility with both FU (SM8) and FK (US8) variants. Confirm RoHS compliance status through official Toshiba documentation before procurement. Ensure the component meets the intended application's reliability standards by consulting the Toshiba Semiconductor Reliability Handbook for derating concepts and failure rate data.

Selection Notes

Select this component when a dual bilateral switch with high speed and low power consumption is required. Consider the 2 V to 12 V supply voltage range and the -40°C to +85°C operating temperature range for environmental suitability. Evaluate the ON resistance and leakage current specifications against the specific signal integrity requirements of the application.

Part Context
