Product details
Overview
TC7SBL384CFU,LF from Toshiba Electronic Devices & Storage Corporation is a low-voltage, low-capacitance CMOS single bus switch designed for analog signal routing in 1.65–3.6 V systems. It features 5.5 Ω typical on-resistance at 3.0 V, 7 pF typical on-capacitance, and active-high output enable (OE) logic. It enables bidirectional signal pass-through in high-speed digital interfaces such as USB 2.0 data lines and memory address buses.
For engineers reviewing the TC7SBL384CFU,LF datasheet, TC7SBL384CFU,LF pinout, TC7SBL384CFU,LF application, or TC7SBL384CFU,LF equivalent, key selection criteria include OE polarity (active-high), −40 to 125 °C operating range, USV package footprint, and sub-10 ns enable/disable timing across 1.8/2.5/3.3 V supply rails.
Technical Context
The TC7SBL384CFU,LF implements a single-pole, single-throw (SPST) analog bus switch with complementary metal-oxide-semiconductor (CMOS) transmission gate architecture. Its active-high OE control directly gates conduction between A and B terminals, with no internal level-shifting or buffering-preserving signal integrity for bidirectional AC-coupled or DC-coupled signals up to 200 MHz.
It integrates power-down protection on all I/O and OE pins, ensuring safe operation during partial power sequencing. The device maintains <±10 µA off-state leakage at 125 °C and supports rail-to-rail analog voltage swing (0 to VCC) on the switch path, compliant with JEDEC JESD78 Class II latch-up immunity.
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 | 5.5 Ω (typ.) @ 3.0 V - Minimizes voltage drop and signal attenuation in high-current data paths. |
| ON Capacitance | 7 pF (typ.) @ 3.0 V - Limits capacitive loading to preserve rise/fall times in >100 Mbps serial links. |
| Enable Polarity | Active-High OE - Simplifies control logic when driven by microcontroller GPIOs without inversion. |
| Operating Temp | −40 to +125 °C - Qualified for under-hood automotive and industrial control applications. |
| Switch Leakage | ≤13 µA (max) @ 125 °C - Ensures signal isolation in powered-down subsystems. |

| B | Switch Input/Output Terminal | Bidirectional analog/digital signal port; connects to load-side of switched path (e.g., peripheral pin). |
| OE | Output Enable (Active-High) | Drives switch ON when high (≥0.7×VCC); places A–B path in high-Z when low (≤0.3×VCC). |
| VCC | Positive Supply | Provides bias for internal CMOS transmission gate; must be decoupled locally with 0.1 µF ceramic capacitor. |
| GND | Ground Reference | Return path for supply and signal currents; requires low-inductance connection to system ground plane. |
Key Features

FAQ
What is the OE polarity of TC7SBL384CFU,LF?
The TC7SBL384CFU,LF uses active-high output enable (OE): the A–B switch path conducts when OE is high (≥0.7×VCC) and enters high-impedance state when OE is low (≤0.3×VCC). This differs from the TC7SBL66CFU,LF, which uses active-low OE. Confirm OE logic level matching before substituting in existing designs.
Does TC7SBL384CFU,LF support 1.8 V operation?
Yes, TC7SBL384CFU,LF operates across 1.65–3.6 V, including full specification compliance at 1.8 V ±0.15 V. At 1.8 V, typical RON is 13 Ω and tPLZ/tPHZ is 13 ns max, enabling use in modern low-voltage SoC interfaces without level shifting.
What is the maximum junction temperature for TC7SBL384CFU,LF?
The TC7SBL384CFU,LF has a maximum junction temperature of +150 °C, derived from its storage temperature rating (−65 to +150 °C) and qualified operating range (−40 to +125 °C ambient). Thermal design must ensure θJA and power dissipation keep TJ ≤150 °C under worst-case load.
Is TC7SBL384CFU,LF RoHS-compliant and halogen-free?
Yes, TC7SBL384CFU,LF meets RoHS Directive 2011/65/EU and is halogen-free per J-STD-709 definition. The USV package uses lead-free matte tin plating and complies with Toshiba's environmental specifications outlined in Rev.2.0.A datasheet dated 2026-04-21.
Can TC7SBL384CFU,LF switch analog audio signals?
Yes, TC7SBL384CFU,LF supports rail-to-rail analog signal switching from 0 V to VCC, making it suitable for line-level audio (e.g., I²S, PCM) within its bandwidth limit (~200 MHz small-signal). Its 7 pF on-capacitance and 5.5 Ω RON minimize THD+N degradation in 16–24 bit audio paths when properly decoupled and layout-controlled.
