Overview
The TC7SBL66CFU,LF(CT is a low voltage and low capacitance CMOS single bus switch manufactured by Toshiba. It operates within a supply voltage range of 1.65 V to 3.6 V. The device features an ON resistance of 5.5 Ω (typical) at VCC = 3 V with VIS = 0 V. Input capacitance is 4 pF, while the switch terminal OFF-capacitance is 3.5 pF and ON-capacitance is 7 pF (typical). The output enable (OE) input must be set low to place the output into the high impedance state. The component supports an operating temperature range of -40 °C to 85 °C for the (CT) suffix variant.
Feature Summary
- Low capacitance design suitable for high-speed signal routing
- Power-down protection provided for all inputs
- Wide operating temperature range available
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. Devices ending in (CT) support -40 °C to 85 °C, while other suffixes may differ. Confirm RoHS compliance status directly with the manufacturer or authorized distributors before finalizing procurement plans.
Selection Notes
Select this component when a single-channel analog bus switch with minimal propagation delay is required. Ensure the control logic matches the active-low OE requirement. Verify that the system voltage stays within the 1.65 V to 3.6 V limit to maintain specified electrical characteristics.
Part Context
This part belongs to the TC7SBL66 series of CMOS digital integrated circuits. It shares functional similarities with the TC7SBL384CFU but differs in the polarity of the output enable control signal. Both are designed for low voltage applications with low on-resistance capabilities.
Replacement Considerations
Check pin compatibility and control logic polarity against alternatives. The TC7SBL384CFU requires the OE input to be set high for high impedance, which is opposite to this part.
