Product details
Overview
TC7MBL3245CFT(EL) from Toshiba Electronic Devices & Storage Corporation is a low-voltage, low-capacitance octal bus switch IC designed for high-speed signal routing in 1.65–3.6 V systems. It features 8-bit bidirectional switching, 6.5 Ω typical on-resistance at 3.0 V, 7.5 pF typical ON-capacitance, and AEC-Q100 Grade 1 qualification for automotive infotainment and ADAS data path isolation.
For engineers reviewing the TC7MBL3245CFT(EL) datasheet, TC7MBL3245CFT(EL) pinout, TC7MBL3245CFT(EL) application, or TC7MBL3245CFT(EL) equivalent, key selection criteria include its -40 to 125 °C operating range (for units manufactured after April 2020), OE-controlled high-impedance state, and TSSOP20B package with 0.65 mm pitch for space-constrained PCB layouts.
Technical Context
This device implements an 8-bit, single-pole double-throw (SPDT) analog bus switch architecture with independent OE control. Its CMOS design enables rail-to-rail signal pass-through with minimal propagation delay and no DC blocking-critical for I²C, SPI, and parallel data bus applications requiring signal integrity across voltage domains.
The switch operates with true bidirectional conduction and includes power-down protection on all I/O and OE pins. Input leakage remains ≤±10 µA over full temperature range, and output enable/disable times are specified at 7–12 ns (max) across 1.8/2.5/3.3 V supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.65–3.6 V: Enables interoperability with 1.8 V, 2.5 V, and 3.3 V logic families without level shifters. |
| ON Resistance | 6.5 Ω typ. @ 3.0 V: Ensures <100 mV voltage drop at 15 mA load-preserves signal swing in high-speed digital interfaces. |
| ON Capacitance | 7.5 pF typ. @ 3.0 V: Limits capacitive loading on source drivers, supporting >100 MHz data rates in low-impedance paths. |
| Operating Temp | -40 to +125 °C (post-April 2020 units): Validated for under-hood automotive modules and industrial controllers. |
| Enable Timing | tPZL/tPZH ≤ 12 ns max @ 1.8 V: Guarantees fast bus arbitration response in real-time communication protocols. |
| AEC-Q100 Grade | Grade 1 qualified: Meets automotive reliability requirements for mission-critical signal routing in non-safety-critical ECUs. |
Pinout & Package
TC7MBL3245CFT(EL) is packaged in a 20-pin TSSOP20B (0.65 mm pitch, 6.5 × 4.4 mm body), optimized for automated assembly and thermal performance in dense automotive PCBs.

|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | A-side I/O terminals | Bidirectional signal ports connected to upstream logic or microcontroller peripherals. |
| 11, 12, 13, 14, 15, 16, 17, 18 | B-side I/O terminals | Bidirectional signal ports routed to downstream devices such as sensors, displays, or memory buffers. |
| 9 | OE (Output Enable) | Active-high control: drives all switches into high-Z when low; enables simultaneous 8-bit bus isolation. |
| 10, 20 | VCC | Single positive supply input; decoupling capacitor required near Pin 10 for noise suppression. |
| 19 | GND | Common reference for all I/O and internal circuitry; must be low-inductance connection to system ground plane. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBT3245APW | Higher RON (7 Ω min), wider VCC range (4.5–5.5 V), no AEC-Q100 qualification | Targeted at 5 V industrial control, not automotive-qualified | Select when operating at 5 V or where automotive qualification is unnecessary. |
| 74LVC245AT20-13 | Direction-controlled transceiver (not bidirectional switch), 3-state outputs only, no analog pass-through | Used for unidirectional data buffering-not suitable for analog or bidirectional signal routing | Choose only for pure digital bus extension with direction pin control. |
Compared with SN74CBT3245APW and 74LVC245AT20-13, the TC7MBL3245CFT(EL) uniquely combines automotive qualification, sub-7 Ω on-resistance, and true bidirectional analog switching in a 1.65–3.6 V domain-making it the sole fit for AEC-Q100-compliant, low-voltage, high-fidelity signal routing.

FAQ
What is the maximum operating temperature range supported by the TC7MBL3245CFT(EL)?
The TC7MBL3245CFT(EL) supports -40 to +125 °C operation-but only for units manufactured after April 2020. Earlier production lots are rated for 0 to +85 °C. Always verify date code or consult Toshiba's latest revision notes to confirm thermal specification applicability for your batch of TC7MBL3245CFT(EL).
Does the TC7MBL3245CFT(EL) require external pull-up resistors on the OE pin?
No, the TC7MBL3245CFT(EL) does not require external pull-up resistors on OE. Its OE input has standard CMOS thresholds (VIH ≥ 0.7×VCC, VIL ≤ 0.3×VCC) and internal ESD protection, allowing direct connection to microcontroller GPIOs. However, unused OE must be tied to VCC or GND per datasheet guidance to prevent floating states that could cause unintended switching in the TC7MBL3245CFT(EL).
Can the TC7MBL3245CFT(EL) be used for analog signal switching, such as audio or sensor voltages?
Yes, the TC7MBL3245CFT(EL) supports analog signal routing within its voltage limits: switch I/O voltage is specified from 0 to VCC, and OFF-state leakage is ≤±10 µA at 125 °C. Its 6.5 Ω RON and 7.5 pF CI/O make it suitable for low-distortion audio paths and precision sensor multiplexing-provided signals remain within the 0–3.6 V range and do not exceed ±50 mA per switch, as defined in the TC7MBL3245CFT(EL) absolute maximum ratings.
Is the TC7MBL3245CFT(EL) pin-compatible with the TC7MBL3245CFN?
No, the TC7MBL3245CFT(EL) is not pin-compatible with the TC7MBL3245CFN. The TC7MBL3245CFT(EL) uses the TSSOP20B package (0.65 mm pitch), while the TC7MBL3245CFN uses the SSOP20 package (0.635 mm pitch) with different mechanical dimensions and land pattern requirements. PCB layout and solder stencil must be redesigned when substituting between these variants of the TC7MBL3245CFT(EL) family.
What is the typical power consumption of the TC7MBL3245CFT(EL) in active operation?
The TC7MBL3245CFT(EL) draws ≤10 µA quiescent supply current (ICC) across 1.65–3.6 V and -40 to +85 °C. At 3.0 V and 25 °C, typical ICC is 1 µA. This ultra-low static power enables use in always-on automotive modules without impacting battery drain-confirming the TC7MBL3245CFT(EL)'s suitability for energy-sensitive applications like telematics wake-up circuits.
