TC7S66F,LF

Overview

The TC7S66F,LF is a high-speed C2MOS bilateral switch manufactured by Toshiba Semiconductor and Storage. It operates on a supply voltage range of 2 V to 12 V with an operating temperature range of -40 °C to +85 °C. The device features a typical propagation delay of 7 ns at 5 V and a maximum quiescent current of 1 μA at 25 °C. On-resistance varies from 90 Ω to 400 Ω depending on the supply voltage. Input protection circuits are included for static discharge and transient excess voltage.

Feature Summary

• High-speed switching capability utilizing silicon gate C2MOS technology
• Low power dissipation characteristics suitable for battery-operated applications
• Integrated input protection against static discharge and transient voltages
• Bilateral signal transmission for both digital and analog control

Applications

• Signal routing in portable electronic devices
• Battery-powered equipment requiring low standby current
• Analog signal switching in consumer electronics
• Digital bus isolation and control

Procurement Notes

Verify the specific package variant (TC7S66F or TC7S66FU) required for the design, as physical dimensions differ between SSOP-5-P-0.95 and SSOP-5-P-0.65A formats. Confirm RoHS compliance status directly with the manufacturer or authorized distributor prior to ordering. Ensure the selected component matches the exact suffix specified in the bill of materials to guarantee correct pin pitch and mechanical fit.

Selection Notes

Select this component when a single-channel bilateral switch is needed for signals up to 12 V. The C2MOS process offers lower power consumption compared to standard CMOS switches. Consider the on-resistance variation across the 2 V to 12 V range when designing for signal integrity. Verify that the application does not require automotive-grade reliability or aerospace certification, as these are excluded from intended use.
