TC7WB66CFK,LF(CT

Overview

The TC7WB66CFK,LF(CT is a digital bus switch IC manufactured by Toshiba Semiconductor and Storage. It features two independent channels with a maximum on-resistance of 30 Ohms. The device operates within a supply voltage range of 1.65 V to 5.5 V and supports surface mount installation in an US-8 package. Key electrical parameters include a maximum power dissipation of 200 mW, a maximum supply current of 50 uA, and propagation delays of 4 ns for turn-on and 4.5 ns for turn-off. It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides bidirectional signal transmission between buses using CMOS logic technology.
• Features low on-resistance to minimize signal attenuation during active states.
• Supports flexible voltage levels compatible with various digital logic families.

Applications

• High-speed data line switching in portable electronic devices
• Signal routing in consumer electronics systems
• Bus isolation in embedded controller interfaces

Procurement Notes

Verify the specific suffix LF(CT) against the manufacturer's official datasheet to confirm packaging type and compliance status. Ensure the component matches the required US-8 package dimensions and thermal characteristics for your PCB layout. Cross-reference the RoHS declaration with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a dual-channel bus switch with moderate speed and wide voltage compatibility is required. Compare the 30 Ohm on-resistance against system impedance requirements to ensure signal integrity. Consider the US-8 package size relative to available board space and verify that the 50 uA supply current fits within the target power budget constraints.

Part Context

This part belongs to Toshiba's TC7WB series of digital bus switches designed for general-purpose applications. It serves as a compact solution for managing signal paths in low-voltage digital circuits. The series emphasizes reliability and ease of integration into modern electronic designs requiring efficient bus management.

Replacement Considerations

Consult official Toshiba documentation for verified substitute part numbers. Do not assume functional equivalence with other manufacturers' components without verifying pinout, voltage ratings, and electrical specifications.
