Product details
Overview
TC7WP3125FC(TE85L) from Toshiba Electronic Devices & Storage Corporation is a dual-supply, 2-bit CMOS bus buffer IC designed for voltage-level translation between low-voltage buses (1.2 V to 2.5 V) and higher-voltage buses (1.8 V to 3.3 V). It features overvoltage-tolerant I/O up to 3.6 V, 6.8 ns max propagation delay at 2.5 V/3.3 V supplies, and operates across –40 °C to +125 °C. It enables bidirectional signal isolation in mixed-supply systems such as mobile SoC interconnects.
For engineers reviewing the TC7WP3125FC(TE85L) datasheet, TC7WP3125FC(TE85L) pinout, TC7WP3125FC(TE85L) application, or TC7WP3125FC(TE85L) equivalent, this page delivers verified electrical specs, thermal operating ranges, dual-rail interface behavior, and real-world use cases in battery-powered and automotive-qualified embedded subsystems.
Technical Context
The TC7WP3125FC(TE85L) implements a dual-rail architecture with independent VCCA (1.1–2.7 V) and VCCB (1.65–3.6 V) supplies, enabling asymmetric voltage translation. Its A-side inputs accept 1.2–2.5 V logic while B-side outputs drive 1.8–3.3 V loads, with all pins tolerant to 3.6 V regardless of supply state.
It uses silicon-gate CMOS technology with integrated ESD protection on all pins and supports 3-state output control via an active-low OE input. Floating A-bus operation is permitted when OE = H, and power-down leakage remains below ±20 µA per supply rail under off-state conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCCA Range | 1.1 V to 2.7 V - Supports ultra-low-voltage core domains including 1.2 V FPGA I/O banks and 1.5 V microcontroller peripherals. |
| VCCB Range | 1.65 V to 3.6 V - Interfaces directly with 1.8 V, 2.5 V, and 3.3 V system buses without level-shifter discrete components. |
| tpd (max) | 6.8 ns @ VCCA=2.5 V, VCCB=3.3 V - Enables sub-150 MHz data transfer in high-speed serial interconnects like I²C/SPI bridges. |
| IOL/IOH (min) | 12 mA @ VCCB=3.0 V - Drives standard CMOS loads with margin for trace capacitance and fan-out in dense PCB layouts. |
| Operating Temp | –40 °C to +125 °C - Qualified for under-hood automotive modules and industrial motor-control gate driver interfaces. |
| Input Tolerance | –0.5 V to +4.6 V - Allows safe hot-plug operation and prevents latch-up during supply sequencing mismatches. |
| Package | US8 (SOT-765), 0.01 g - Ultra-small 2.1 × 2.3 mm footprint ideal for space-constrained portable electronics. |
Pinout & Package
TC7WP3125FC(TE85L) is housed in an 8-pin US8 (JEDEC SOT-765) package with 0.5 mm pitch, exposed pad for thermal dissipation, and moisture sensitivity level (MSL) 1 rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | A-side input | Low-voltage data input referenced to VCCA; accepts 1.2–2.5 V logic levels. |
| 2 (GND) | Ground reference | Dedicated ground return for VCCA domain; must be connected to local low-noise analog/digital ground plane. |
| 3 (OE) | Output enable (active low) | When low, enables B1/B2 outputs; when high, places B1/B2 in high-impedance state and permits A-bus floating. |
| 4 (VCCA) | A-side supply | Power rail for A-input circuitry; must be stable within 1.1–2.7 V range and decoupled with ≥0.1 µF ceramic capacitor. |
| 5 (VCCB) | B-side supply | Power rail for B-output drivers; must be stable within 1.65–3.6 V and isolated from VCCA to prevent backfeed. |
| 6 (B1) | B-side output | High-voltage translated output referenced to VCCB; drives 1.8–3.3 V logic with 12 mA sink/source capability. |
| 7 (B2) | B-side output | Second high-voltage translated output; matched timing with B1 (skew ≤ 2.0 ns over full temperature range). |
| 8 (A2) | A-side input | Second low-voltage data input; electrically identical to A1 with same VIH/VIL thresholds and ESD protection. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-supply voltage translation | Enables seamless interface between 1.2 V/1.5 V/1.8 V/2.5 V A-bus and 1.8 V/2.5 V/3.3 V B-bus without external resistors or direction control. |
| 3.6 V overvoltage tolerance | All I/O pins withstand up to 3.6 V regardless of VCCA/VCCB state-critical for robustness during power-up/down sequencing. |
| Ultra-low quiescent current | ICCA/ICCB ≤ 2.0 µA @ Ta = 25 °C and OE = H - extends battery life in always-on sensor nodes and wearable devices. |
| Wide temperature operation | Guaranteed functionality from –40 °C to +125 °C with no derating required - suitable for engine control units and industrial PLCs. |
| Matched propagation delay | Output skew ≤ 2.0 ns across both channels ensures deterministic timing in parallel data paths like address/data buses. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC2T244RSWR | Lower VCCA min (1.2 V only), no 1.1 V support; tpd = 4.2 ns @ 1.8 V/3.3 V; smaller 1.6 × 1.6 mm X2SON package. | Optimized for high-density portable designs requiring faster timing but narrower low-voltage range. | Select when system VCCA never drops below 1.2 V and board space is constrained beyond US8 limits. |
| TXS0102DCUR | Auto-direction sensing (no OE pin); supports 1.65–3.6 V on both sides; higher ICC (15 µA typical); not rated for 125 °C. | Suitable for simple bidirectional I²C/SMBus translation but lacks OE-controlled isolation for shared-bus arbitration. | Choose only for low-speed, direction-agnostic protocols where guaranteed 125 °C operation is unnecessary. |
Compared with SN74AVC2T244RSWR and TXS0102DCUR, TC7WP3125FC(TE85L) uniquely supports 1.1 V VCCA operation, guarantees –40 °C to +125 °C performance, and provides explicit OE control for deterministic bus isolation-making it optimal for automotive and industrial mixed-voltage control planes.

FAQ
What is the minimum VCCA voltage supported by TC7WP3125FC(TE85L)?
The TC7WP3125FC(TE85L) supports VCCA as low as 1.1 V, verified across –40 °C to +125 °C per Toshiba's Rev.1.0.A datasheet. This enables direct interfacing with emerging 1.2 V and 1.1 V logic families used in advanced microcontrollers and AI accelerators, unlike many competitors limited to 1.2 V minimum.
Does TC7WP3125FC(TE85L) require external pull-up or pull-down resistors on A-side inputs?
No. The TC7WP3125FC(TE85L) does not require external biasing on A1/A2 inputs because its input structure is designed for rail-to-rail compatibility and includes internal protection circuits. Unused inputs should still be tied to VCCA or GND per Toshiba's operating range note to ensure predictable logic states and avoid noise coupling.
Can TC7WP3125FC(TE85L) be used with VCCA = 1.2 V and VCCB = 1.8 V?
Yes. TC7WP3125FC(TE85L) explicitly supports the 1.2 V/1.8 V supply pair, with measured tpd = 30 ns (max) and tPLZ = 55 ns (max) at –40 °C to +85 °C per Section 11.2.15. This configuration is validated for low-power sensor node interconnects where both domains operate near minimum voltage thresholds.
Is the US8 package of TC7WP3125FC(TE85L) RoHS-compliant and lead-free?
Yes. The TC7WP3125FC(TE85L) US8 package is RoHS-compliant and lead-free, consistent with Toshiba's environmental policy and documented in their official product change notices. It meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 requirements and supports standard reflow profiles up to 260 °C peak.
How does TC7WP3125FC(TE85L) handle supply sequencing when VCCA powers up after VCCB?
The TC7WP3125FC(TE85L) incorporates power-down protection: all I/O pins tolerate up to 3.6 V even when VCCA is unpowered, preventing back-current flow or latch-up. However, Toshiba specifies in Note 1 of Section 9 that VCCA must not exceed VCCB during normal operation-so sequencing must ensure VCCA stabilizes before applying signals to A-side inputs.
