Overview
The TC7SBL384CFU,LF(CT 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) suffix variant. The device features an ON resistance of 5.5 Ω typical at 3.0 V and an ON capacitance of 7 pF. It includes power-down protection for inputs and utilizes a USV package.
Feature Summary
- Low capacitance design minimizes signal distortion in high-speed data lines
- Power-down protection prevents leakage current during low-power states
- Wide operating temperature range suitable for industrial environments
Applications
- Portable devices requiring low power consumption
- High-speed data transmission lines
- Consumer electronics with limited supply voltage
Procurement Notes
Verify the specific ordering suffix (CT) to confirm the extended temperature rating of -40 to 85 °C versus the standard -40 to 125 °C. Ensure compatibility with the USV package dimensions during PCB layout. Confirm RoHS compliance status through official distributor channels prior to procurement.
Selection Notes
Select this component when a single-channel analog bus switch with minimal propagation delay is required. The low ON resistance ensures efficient signal transfer. Consider the OE input logic polarity, as this model requires a high signal for high-impedance state activation, differing from complementary variants.
Part Context
This part belongs to the TC7SBL series of low-voltage, low-capacitance CMOS digital integrated circuits. It shares functional similarities with the TC7SBL66CFU but differs in control logic polarity. Both are designed for applications demanding minimal signal degradation in compact form factors.
Replacement Considerations
The TC7SBL66CFU is a functional alternative within the same family. Note that the TC7SBL66CFU requires a low signal on the OE input to enter the high-impedance state, whereas the TC7SBL384CFU requires a high signal. Verify logic level compatibility before substitution.
