Product details
Overview
TC7SBL66CFU,LF from Toshiba Electronic Devices & Storage Corporation is a low-voltage, low-capacitance CMOS single bus switch designed for analog signal routing in high-speed digital systems. It features 5.5 Ω typical ON-resistance at 3.0 V, 7 pF typical ON-capacitance, and operates across 1.65–3.6 V supply with -40 to 125 °C temperature range - enabling use in USB 2.0 data line switching and I²C bus isolation.
For engineers reviewing the TC7SBL66CFU,LF datasheet, TC7SBL66CFU,LF pinout, TC7SBL66CFU,LF application, or TC7SBL66CFU,LF equivalent, key selection criteria include OE-active-low control logic, USV package footprint, sub-10 ns enable/disable timing, and guaranteed power-down protection on all I/O and OE pins.
Technical Context
The TC7SBL66CFU,LF implements a single-pole single-throw (SPST) analog bus switch with complementary MOSFET structure, where conduction occurs between A and B terminals when OE is low. Its design minimizes charge injection and capacitive coupling via matched transistor sizing and guard-ring layout.
It supports bidirectional analog/digital signal pass-through with rail-to-rail voltage handling (0 to VCC), exhibits <±1.0 µA input leakage at 125 °C, and maintains stable RON across VCC = 1.65–3.6 V and VIS = 0–2.4 V - critical for maintaining signal integrity in mixed-signal SoC interconnects.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.65–3.6 V - compatible with 1.8 V and 3.3 V logic domains without level shifters |
| ON Resistance | 5.5 Ω typ. @ 3.0 V - ensures <0.1% signal attenuation for 10 mA loads |
| ON Capacitance | 7 pF typ. @ 3.0 V - limits bandwidth degradation in >100 MHz signal paths |
| Enable Timing | 6 ns max tPZL/tPZH @ 3.3 V - enables cycle-accurate bus arbitration in fast peripherals |
| Operating Temp | -40 to +125 °C - qualified for under-hood automotive and industrial control environments |
| Input Leakage | ±1.0 µA max @ 125 °C - prevents false triggering in high-impedance sensor interfaces |
Pinout & Package
TC7SBL66CFU,LF is housed in a 5-pin USV (Ultra Small Outline) package measuring 1.2 × 1.0 × 0.35 mm, with 0.5 mm pitch and exposed pad for thermal dissipation. The package is RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Switch Input/Output Terminal | Bidirectional analog/digital signal path; supports rail-to-rail voltage swing (0 to VCC) |
| B | Switch Input/Output Terminal | Complementary terminal to A; forms low-RON, low-CI/O conductive path when OE = L |
| OE | Active-Low Output Enable | Drives internal FET gate; must be ≤0.3×VCC to enable conduction; high-Z state when >0.7×VCC |
| VCC | Positive Supply | Power rail for internal logic and switch biasing; decoupling capacitor required within 1 mm |
| GND | Ground Reference | Common return for VCC, OE, A, and B; connects to exposed thermal pad for thermal stability |
Key Features
| Feature | Design Value |
|---|---|
| Low ON-capacitance | 7 pF typ. - preserves signal edge rate in high-speed data lines (e.g., USB D+/D−) |
| Power-down protection | IOFF ≤ ±1.0 µA @ VCC = 0 V - prevents back-drive current during system sleep states |
| Wide temp operation | -40 to +125 °C - eliminates derating requirements in engine-control or motor-drive modules |
| ESD robustness | ±2 kV HBM - protects against assembly-handling and board-level ESD events without external clamps |
| Low propagation delay | <1 ns intrinsic delay - avoids timing skew in synchronous bus architectures |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBTLV3245APW | 8-bit wide, 3-state outputs, 5 V tolerant inputs, higher RON (6.5 Ω typ.) | Requires external level shifting for 1.8 V systems; better suited for parallel bus isolation than single-line switching | Select when multi-bit channel isolation is needed and 5 V compatibility is required |
| TS3A24159YZPR | 2-channel, dual SPDT, 1.65–3.6 V, lower CI/O (5.5 pF), but higher RON (7.5 Ω typ.) | Supports crosspoint routing; lacks power-down protection on OE, limiting use in always-on systems | Prefer for compact 2×2 signal matrix designs where ultra-low capacitance outweighs RON penalty |
Compared with SN74CBTLV3245APW and TS3A24159YZPR, TC7SBL66CFU,LF delivers optimal balance of low RON, low CI/O, and guaranteed power-down protection in a minimal 5-pin USV footprint - making it preferred for single-line, high-reliability analog switching where board space and thermal constraints are critical.

FAQ
What is the logic polarity of the OE pin on TC7SBL66CFU,LF?
The OE (Output Enable) pin on TC7SBL66CFU,LF is active-low: the A–B switch path is enabled when OE is driven to GND (≤0.3×VCC), and placed in high-impedance state when OE is pulled to VCC (≥0.7×VCC). This differs from the TC7SBL384CFU, which uses active-high OE logic.
Does TC7SBL66CFU,LF support rail-to-rail analog signal switching?
Yes, TC7SBL66CFU,LF supports bidirectional rail-to-rail analog signal switching across the full 0 V to VCC range. Its CMOS transmission gate architecture ensures linear conduction without body diode conduction, enabling clean pass-through of AC-coupled or DC-biased signals up to 3.6 V.
What is the maximum operating temperature specification for TC7SBL66CFU,LF?
The TC7SBL66CFU,LF is rated for continuous operation from -40 °C to +125 °C. This extended temperature grade applies to devices with ordering part numbers ending in ",LF" - confirmed in Toshiba's Rev. 2.0.A datasheet section 3, Note 1.
Is TC7SBL66CFU,LF compatible with 1.8 V logic systems?
Yes, TC7SBL66CFU,LF operates down to VCC = 1.65 V, making it fully compatible with 1.8 V logic families. VIH and VIL thresholds scale with VCC (VIH ≥ 0.7×VCC, VIL ≤ 0.3×VCC), ensuring reliable OE control and noise margin in 1.8 V systems.
Does TC7SBL66CFU,LF include ESD protection on all pins?
Yes, TC7SBL66CFU,LF integrates on-chip ESD protection circuits on all inputs and I/O terminals (A, B, OE), rated to ±2 kV per Human Body Model (HBM). This eliminates the need for external TVS diodes in most board-level ESD environments.
