Overview
The TC7SBL66CFU,LF is a low-voltage, low-capacitance CMOS single bus switch manufactured by Toshiba. It operates within a supply voltage range of 1.65 V to 3.6 V and supports an operating temperature range of -40 °C to 85 °C for the (CT) variant. The device features a typical ON-resistance of 5.5 Ω at 3.0 V and a typical ON capacitance of 7 pF. It utilizes a USV package with five pins. Power-down protection is included for inputs, and static discharge protection is provided on all input terminals.
Feature Summary
- Low capacitance design minimizes signal propagation delay
- Wide operating temperature range suitable for industrial environments
- Power-down protection prevents leakage current during power-off states
Applications
- Portable devices requiring low power consumption
- High-speed data transmission lines
- Battery-powered equipment
Procurement Notes
Verify the specific ordering suffix to confirm the operating temperature range, as variants ending in (CT) support up to 85 °C while others extend to 125 °C. Confirm RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Ensure the package type matches the PCB footprint requirements.
Selection Notes
Select this component when low capacitance and low ON-resistance are critical for maintaining signal integrity in high-speed applications. Ensure the supply voltage remains within the 1.65 V to 3.6 V range. Consider the OE pin logic level requirements, as the TC7SBL66CFU requires a low signal to enable the high-impedance state.
Part Context
This part belongs to the TC7SBL series of low-voltage, low-capacitance CMOS digital integrated circuits. It is designed alongside similar parts like the TC7SBL384CFU, differing primarily in control logic polarity. The series targets applications demanding minimal signal distortion and low power usage in compact form factors.
Replacement Considerations
Direct substitutes include other single bus switches from Toshiba with matching voltage ranges and package types. Verify that any replacement maintains the same low capacitance characteristics and control logic polarity to ensure circuit compatibility without redesign.
