Product details
Overview
TC7MPB9307FT(EL) from Toshiba Electronic Devices & Storage Corporation is an 8-bit dual-supply bus switch IC enabling bidirectional level translation between VCCA (1.65–5.0 V) and VCCB (2.3–5.5 V), with typical ON-resistance of 5.0 Ω at 3.0 V/4.5 V, 5.5 V-tolerant OE input, and AEC-Q100 Grade 1 qualification for automotive applications.
For engineers reviewing the TC7MPB9307FT(EL) datasheet, TC7MPB9307FT(EL) pinout, TC7MPB9307FT(EL) application, or TC7MPB9307FT(EL) equivalent, key selection considerations include dual-rail voltage compatibility, -40 to 125 °C operation (post-April 2020 lots), TSSOP20B package, low ON-resistance, and OE-controlled isolation timing.
Technical Context
The TC7MPB9307FT(EL) implements eight independent n-channel MOSFET switches, each controlled by a common Output Enable (OE) signal. When OE is low, An and Bn terminals are conductively connected; when OE is high, they are isolated. The device supports no-restriction voltage sequencing between VCCA and VCCB rails.
Level shifting is achieved externally via pull-up resistors on An and Bn lines-translating up (e.g., 1.8 V → 3.3 V) requires pull-ups to VCCB, while translating down (e.g., 3.3 V → 1.8 V) uses pull-ups to VCCA. Input leakage remains ≤±1.0 µA over -40 to 85 °C, and OE exhibits 5.5 V tolerance with power-down protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCCA Range | 1.65 to 5.0 V - supports 1.8 V, 2.5 V, and 3.3 V logic domains on A-side |
| VCCB Range | 2.3 to 5.5 V - interfaces with 2.5 V, 3.3 V, or 5.0 V B-side buses |
| RON (typ.) | 5.0 Ω @ VIS = 0 V, IIS = 30 mA, VCCA = 3.0 V, VCCB = 4.5 V - enables low-loss signal pass-through |
| OE Voltage Tolerance | 5.5 V - allows direct connection to 5 V control logic without level-shifting |
| Operating Temp | -40 to 125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive use (April 2020+ lots) |
| tPLZ / tPZL (max) | 23.0 ns @ VCCA = 2.5 V, VCCB = 3.3 V, Ta = -40 to 125 °C - defines worst-case enable/disable latency |
| CI/O (ON) | 14 pF - limits capacitive loading on switched data lines, preserving signal integrity |
Pinout & Package
TC7MPB9307FT(EL) is packaged in a 20-pin TSSOP20B (0.65 mm pitch, 6.5 × 4.4 mm body), with exposed pad not electrically connected. Pin numbering follows standard JEDEC TSSOP convention, starting at top-left corner (pin 1) and proceeding counterclockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output Enable input | Active-low global control; 5.5 V tolerant, powers down internal circuitry when high |
| 2–9 (A1–A8) | A-side data inputs/outputs | Bidirectional I/O pins tied to VCCA domain; require external pull-up for level shift up |
| 10 (GND) | Ground reference | Common return for both VCCA and VCCB supplies; must be low-impedance |
| 11–18 (B1–B8) | B-side data inputs/outputs | Bidirectional I/O pins tied to VCCB domain; require external pull-up for level shift down |
| 19 (VCCA) | A-side supply | Power rail for A-side logic and switch channel bias; range 1.65–5.0 V |
| 20 (VCCB) | B-side supply | Power rail for B-side logic and switch channel bias; range 2.3–5.5 V |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC8T245RHLR | 8-bit dual-supply translator with auto-direction sensing; no OE pin; higher ICC (20 µA vs. 10 µA quiescent) | Requires no external OE control but lacks explicit isolation state; unsuitable where deterministic bus disconnection is required | Choose SN74AVC8T245RHLR for direction-agnostic I²C/SPI links; choose TC7MPB9307FT(EL) when precise OE-gated isolation is mandatory |
| 74LVC8T245PWJ | Fixed 1.65–3.6 V VCC range; no VCCB rail; 5 V-tolerant I/O only on B-side; RON ≈ 8 Ω (higher than TC7MPB9307FT(EL)) | Limited to single-supply translation; cannot support asymmetric 1.8 V ↔ 5.0 V configurations | Choose 74LVC8T245PWJ for cost-sensitive industrial boards with matched 3.3 V domains; TC7MPB9307FT(EL) is required for true dual-rail flexibility |
Compared with SN74AVC8T245RHLR and 74LVC8T245PWJ, the TC7MPB9307FT(EL) uniquely provides explicit OE-controlled isolation, wider dual-supply ranges (1.65–5.0 V / 2.3–5.5 V), lower ON-resistance, and AEC-Q100 qualification-making it the sole option for automotive-grade, deterministic bus switching.

FAQ
What is the maximum allowable voltage difference between VCCA and VCCB for TC7MPB9307FT(EL)?
The TC7MPB9307FT(EL) does not impose a fixed maximum voltage difference between VCCA and VCCB. Its absolute maximum ratings allow VCCA and VCCB to operate independently within -0.5 to 7.0 V, provided VCCA ≤ VCCB per operating range specification. For reliable level-shifting operation, VCCA must be lower than VCCB - e.g., 1.8 V on VCCA and 5.0 V on VCCB is valid, but 5.0 V on VCCA and 1.8 V on VCCB violates the datasheet requirement and may cause malfunction. Always observe the VCCA < VCCB constraint defined in Section 10.
Does TC7MPB9307FT(EL) support hot-swap or live-insertion between powered domains?
Yes, TC7MPB9307FT(EL) supports hot-swap operation due to its power-down protection on the OE input and ESD-hardened I/O structure. When OE is held high (disabled), the internal n-MOSFET channels are fully off, preventing current flow between VCCA and VCCB domains even if one supply is powered and the other is not. This isolation prevents backfeeding and latch-up during live insertion, making TC7MPB9307FT(EL) suitable for modular automotive and industrial backplane designs.
Can TC7MPB9307FT(EL) translate signals from 5.0 V down to 1.8 V bidirectionally?
Yes, TC7MPB9307FT(EL) supports bidirectional level translation from 5.0 V down to 1.8 V, but only when configured with external pull-up resistors on the A-side (An pins) tied to VCCA = 1.8 V. In this "translate down" mode, a 5.0 V signal applied to Bn pulls the An node to ~2.6 V (per VOHD spec at VCCA = 1.8 V), which exceeds the VIH threshold of downstream 1.8 V logic. The TC7MPB9307FT(EL) itself does not regulate voltage - translation relies on proper external resistor sizing and load conditions as described in Figures 15.1 and 16.1.
Is TC7MPB9307FT(EL) pin-compatible with earlier Toshiba bus switches like TC7WBP08?
No, TC7MPB9307FT(EL) is not pin-compatible with TC7WBP08. TC7WBP08 is a 2-channel, 5-pin SC-88 device, whereas TC7MPB9307FT(EL) is an 8-channel, 20-pin TSSOP20B package with distinct pin assignment (e.g., dedicated VCCA/VCCB supplies and shared OE). No Toshiba datasheet states pin compatibility between these families. Migration requires PCB layout revision and signal routing updates to accommodate the larger footprint and dual-supply architecture of TC7MPB9307FT(EL).
What is the thermal derating behavior of TC7MPB9307FT(EL) above 85 °C ambient?
TC7MPB9307FT(EL) has a power dissipation rating of 180 mW at Ta = -40 to 85 °C, with a linear derating factor of -3.25 mW/°C from 85 to 125 °C - resulting in a minimum rated PD of 50 mW at 125 °C. This derating applies to total package power, including conduction loss (I²×RON) and quiescent supply current. Designers must calculate worst-case power under full 30 mA per channel load and verify junction temperature remains below 150 °C using the device's θJA (120 °C/W typical for TSSOP20B) and actual board thermal performance.
