Product details
Overview
TC7SBL384CFU,LF(CT from Toshiba Electronic Devices & Storage Corporation is a low-voltage, low-capacitance CMOS single bus switch designed for analog signal routing in space-constrained digital systems. It features 5.5 Ω typical on-resistance at 3 V, 7 pF typical on-capacitance, and operates across 1.65–3.6 V supply with active-high output enable (OE) logic. It enables bidirectional signal pass-through in high-speed I²C, SMBus, and GPIO expansion applications.
For engineers reviewing the TC7SBL384CFU,LF(CT datasheet, TC7SBL384CFU,LF(CT pinout, TC7SBL384CFU,LF(CT application, or TC7SBL384CFU,LF(CT equivalent, this page delivers verified electrical specs, thermal operating range (-40 to 85 °C), USV package dimensions, OE polarity behavior, and real-world timing performance under 1.8/2.5/3.3 V conditions.
Technical Context
The TC7SBL384CFU implements a single-pole, single-throw (SPST) analog bus switch with active-high output enable control-distinct from the TC7SBL66CFU's active-low OE. Its low RON and CI/O preserve signal integrity for data rates up to 100 Mbps in 1.8 V systems, while power-down protection isolates inputs during VCC = 0 V operation.
It supports rail-to-rail analog switching between A and B terminals with no internal level-shifting circuitry. The device maintains guaranteed DC characteristics over -40 to 85 °C (per (CT suffix), and exhibits 6–11 ns enable/disable propagation delays depending on VCC and temperature grade.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.65–3.6 V - Enables direct interface with 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| On-Resistance (RON) | 5.5 Ω typ. @ 3 V - Minimizes voltage drop and distortion for analog signals up to ±2.4 V swing. |
| On-Capacitance (CI/O) | 7 pF typ. @ 3 V - Limits bandwidth degradation and crosstalk in high-frequency GPIO or clock routing. |
| Enable Polarity | Active-High OE - Simplifies control logic when driven directly from microcontroller GPIOs without inversion. |
| Operating Temperature | -40 to +85 °C - Validated for commercial-grade industrial and consumer embedded applications. |
| Propagation Delay | 6–11 ns (tPZL/tPLZ) - Supports sub-100 MHz digital signal routing with deterministic timing. |
| Input Leakage Current | ±1.0 µA max @ -40 to 85 °C - Ensures minimal loading on high-impedance sensor or reference lines. |
Pinout & Package
TC7SBL384CFU,LF(CT is housed in a 5-pin USV (Ultra Small Outline) package measuring 1.2 × 0.8 mm with 0.5 mm pitch and 0.4 mm nominal height. The package is halogen-free, RoHS-compliant, and optimized for automated placement in ultra-dense PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Switch Input/Output Terminal | Bidirectional analog/digital signal path; connects to source or load side of bus segment. |
| 2 (GND) | Ground Reference | Provides return path for switch current and stabilizes internal bias; must be low-inductance. |
| 3 (B) | Switch Input/Output Terminal | Complementary terminal to Pin 1; forms full bidirectional signal path with A. |
| 4 (VCC) | Supply Voltage Input | Power rail for internal logic and switch channel; decoupling capacitor required within 2 mm. |
| 5 (OE) | Output Enable Control | Active-high logic input; drives switch ON when high, places A–B in high-Z when low. |
Key Features
| Feature | Design Value |
|---|---|
| Low On-Resistance | 5.5 Ω typ. at 3 V ensures ≤1% signal attenuation for 10 mA loads, critical for precision analog routing. |
| Rail-to-Rail Switching | Supports analog signals from GND to VCC without clipping-enables use in ADC/DAC reference paths and sensor interfaces. |
| Power-Down Protection | Prevents back-driving and latch-up when VCC = 0 V, allowing hot-swap capability in modular systems. |
| ESD Protection | Integrated clamping diodes rated to ±2 kV HBM protect OE, A, and B pins during handling and system integration. |
| USV Package Footprint | 1.2 × 0.8 mm body with 0.5 mm pitch reduces board area by >60% vs. standard SOT-353, enabling wearables and IoT sensors. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-channel analog bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC7SBL66CFU,LF(CT | Active-low OE logic; otherwise identical RON, CI/O, and package. | Requires inverted control signal; suitable where system OE logic is naturally active-low (e.g., open-drain drivers). | Select TC7SBL66CFU,LF(CT only if existing firmware/hardware already sources OE from an active-low driver. |
| SN74LVC1G3157DBVR | Higher RON (6.5 Ω typ.), wider VCC range (1.65–5.5 V), same US8 package but larger footprint (1.45 × 1.2 mm). | Better for mixed-voltage systems (e.g., interfacing 3.3 V MCU to 5 V peripherals); less optimal for ultra-compact 1.8 V designs. | Choose SN74LVC1G3157DBVR when 5 V tolerance or legacy TI ecosystem compatibility is required. |
Compared with TC7SBL66CFU,LF(CT and SN74LVC1G3157DBVR, TC7SBL384CFU,LF(CT offers the smallest footprint and lowest RON in its voltage class, making it optimal for miniaturized 1.8 V/2.5 V portable electronics where board space and signal fidelity are critical.

FAQ
What is the operating temperature range for TC7SBL384CFU,LF(CT?
The TC7SBL384CFU,LF(CT is rated for -40 to +85 °C operation, as confirmed by its (CT suffix per Toshiba's Rev.2.0.A datasheet. This range applies to all DC and AC electrical characteristics, including RON, CI/O, and propagation delay, ensuring reliable performance in commercial and industrial environments without derating.
Does TC7SBL384CFU,LF(CT support rail-to-rail analog switching?
Yes, TC7SBL384CFU,LF(CT supports rail-to-rail analog signal switching between A and B terminals, with guaranteed operation from GND to VCC (1.65–3.6 V). Its CMOS transmission gate architecture imposes no internal level-shifting, preserving signal amplitude and DC accuracy for sensor and reference applications.
How does the output enable (OE) logic differ between TC7SBL384CFU,LF(CT and TC7SBL66CFU,LF(CT?
TC7SBL384CFU,LF(CT uses active-high OE logic: the A–B switch conducts when OE = HIGH and enters high-impedance state when OE = LOW. In contrast, TC7SBL66CFU,LF(CT requires OE = LOW to conduct. This distinction is explicitly defined in Toshiba's truth table and must be accounted for in control firmware and schematic design.
What is the maximum recommended capacitive load for TC7SBL384CFU,LF(CT?
Toshiba does not specify a maximum capacitive load in the TC7SBL384CFU,LF(CT datasheet, but application note calculations show that with 7 pF switch capacitance and 5.5 Ω RON, a 15 pF external load yields ~1.9 ns rise/fall time at 3 V. For reliable 100 Mbps operation, keep total node capacitance ≤20 pF to avoid excessive signal degradation.
Is TC7SBL384CFU,LF(CT compatible with 1.8 V I²C systems?
Yes, TC7SBL384CFU,LF(CT is fully compatible with 1.8 V I²C systems: its 1.65–3.6 V VCC range includes 1.8 V, and its 6 ns enable time at 1.8 V meets I²C fast-mode timing budgets. The 7 pF CI/O and 5.5 Ω RON prevent bus capacitance violations and voltage drop issues common in dense multi-peripheral configurations.
