Overview
The TC7WB67CFK,LF(CT is a general-purpose digital bus switch IC manufactured by Toshiba Semiconductor and Storage. It features a dual bus switch architecture with two independent channels. The device operates within a supply voltage range of 1.65 V to 5.5 V, supporting low-voltage applications. Key electrical parameters include a maximum on-resistance of 30 Ohms and a maximum power dissipation of 200 mW. Timing characteristics specify a maximum propagation delay of 4 ns for turn-on and 4.5 ns for turn-off. The component functions across an extended temperature range from -40°C to +85°C and utilizes an 8-pin US-8 surface-mount package.
Feature Summary
- Dual-channel configuration providing independent signal routing capabilities
- Low capacitance design suitable for high-speed data transmission lines
- Wide operating voltage compatibility spanning standard logic levels
Applications
- Portable equipment requiring low-power signal switching
- Consumer electronics utilizing multiple data buses
- Industrial control systems needing isolated signal paths
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm packaging format. The part number indicates availability in cut tape or reel configurations. Ensure compliance with RoHS directives as specified in the official datasheet. Cross-reference the Mouser number 757-TC7WB67CFKLFCT for distributor-specific handling requirements. Confirm lead times directly with authorized suppliers prior to procurement planning.
Selection Notes
Select this component when dual-channel isolation is required within a compact footprint. The 1.65 V minimum supply voltage makes it suitable for battery-operated devices. Evaluate the 30 Ohm on-resistance against load requirements to ensure signal integrity. The US-8 package offers a space-efficient solution for dense PCB layouts compared to larger DIP alternatives.
Part Context
This component belongs to the TC7WB series of digital bus switches from Toshiba. It serves as a signal routing element within complex electronic systems. The device complements other logic families by providing dedicated switching functionality without requiring external discrete components. Its integration into the broader Toshiba portfolio supports standardized design methodologies for mixed-signal applications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should consult the official Toshiba datasheet for pin-compatible alternatives within the same product family. Verify electrical parameter overlaps before considering cross-brand replacements.
