Product details
Overview
7UL1T126FU,LF from Toshiba Electronic Devices & Storage Corporation is a single-channel CMOS bus buffer with 3-state output, designed for level-translating signal routing in low-voltage digital systems. It supports bidirectional voltage translation (up/down), operates from 2.3 V to 3.6 V, tolerates 3.6 V inputs, and delivers ±8 mA drive capability across –40 °C to +125 °C - enabling use in automotive body control modules and industrial sensor interfaces.
For engineers reviewing the 7UL1T126FU,LF datasheet, 7UL1T126FU,LF pinout, 7UL1T126FU,LF application, or 7UL1T126FU,LF equivalent, key selection criteria include its 3.6 V-tolerant inputs, power-down output protection, wide temperature range, and USV package compatibility with space-constrained PCB layouts.
Technical Context
This device implements a single non-inverting buffer with active-low 3-state enable (G), supporting voltage-level interoperability between 1.8 V/2.5 V and 3.3 V domains. Its input structure enables both up-translation (e.g., 1.8 V logic driving 3.3 V rail) and down-translation (e.g., 3.3 V input accepted on 2.5 V supply), verified across all operating voltages (2.3–3.6 V).
The 3-state output features power-down leakage protection (IOFF ≤ ±80 µA at 125 °C) and 3.6 V tolerance independent of VCC, while propagation delays remain tightly controlled: tPLH/tPHL ≤ 5.2 ns (VCC = 3.0–3.6 V, Ta = 125 °C), ensuring timing integrity in high-speed serial data paths and microcontroller peripheral expansion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.3 V to 3.6 V - supports dual-rail systems and battery-powered designs with brown-out resilience. |
| Input Voltage Range | 0 V to 3.6 V - enables 3.6 V-tolerant inputs regardless of VCC, eliminating external clamping diodes. |
| Output Drive | ±8 mA - sufficient to drive 15 pF loads with <7.6 ns propagation delay at 125 °C, suitable for FPGA I/O expansion. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive and industrial motor control environments. |
| Power-Down Leakage | IOFF ≤ ±80 µA at 125 °C - prevents back-driving and current leakage when VCC is off, critical for hot-swap applications. |
| Propagation Delay | tPLH/tPHL ≤ 5.2 ns (VCC = 3.0–3.6 V, CL = 15 pF, Ta = 125 °C) - ensures sub-6 ns timing margin in 100 MHz clock domains. |
| Input Capacitance | CIN = 3 pF - minimizes capacitive loading on upstream drivers, preserving signal edge rates in dense routing. |
Pinout & Package
7UL1T126FU,LF is housed in a 5-pin USV (Ultra Small Outline) package (1.2 × 0.8 mm, 0.4 mm pitch), optimized for ultra-compact PCB footprints in wearables and IoT edge nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Buffer Input | Accepts logic signals from any source within 0–3.6 V; supports level translation without external biasing. |
| 2 (G) | Active-Low Output Enable | Drives output to high-impedance state when high; enables shared-bus arbitration and power-gated subsystems. |
| 3 (Y) | 3-State Buffer Output | Delivers inverted logic state only when G = L; provides 3.6 V-tolerant output even during VCC power-down. |
| 4 (VCC) | Positive Supply | Supplies core logic and output stage; range 2.3–3.6 V defines compatible host domain voltage. |
| 5 (GND) | Ground Reference | Common return path for supply and I/O; must be low-inductance for stable noise immunity at high speed. |
Key Features
| Feature | Design Value |
|---|---|
| Voltage Translation | Supports both up-translation (e.g., 1.8 V → 3.3 V) and down-translation (e.g., 3.3 V → 2.5 V) without external components. |
| 3.6 V-Tolerant Inputs | Accepts 3.6 V logic levels regardless of VCC setting (2.3–3.6 V), simplifying mixed-voltage interface design. |
| Power-Down Protection | IOFF ≤ ±80 µA at 125 °C ensures no back-current flow when VCC = 0 V, enabling safe hot-plug operation. |
| Wide Temperature Range | Specified from –40 °C to +125 °C with full DC/AC performance, meeting AEC-Q100 Grade 1 requirements. |
| Low Input Capacitance | CIN = 3 pF reduces loading on driving sources, maintaining signal integrity in high-frequency data lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0101DCKR | Single-channel, 1.65–5.5 V supply, auto-direction sensing, higher ICC (10 µA typ.), larger SC70-6 package. | Requires no enable signal but lacks 3-state control; better for I²C, less suited for shared-bus arbitration. | Select TXS0101DCKR when direction detection is preferred over explicit 3-state control and board space permits SC70-6. |
| SN74LVC1T45DBVR | Single-channel, dual-supply (1.65–5.5 V), true bidirectional translation, 3-state enable, SOT-23-6 package. | Supports true bidirectional data flow (e.g., SDIO), whereas 7UL1T126FU,LF is unidirectional with separate enable. | Select SN74LVC1T45DBVR when bidirectional communication is required; otherwise, 7UL1T126FU,LF offers smaller USV footprint and lower CIN. |
Compared with TXS0101DCKR and SN74LVC1T45DBVR, the 7UL1T126FU,LF provides the smallest footprint (USV), lowest input capacitance (3 pF), and highest temperature rating (125 °C), making it optimal for space- and thermal-constrained unidirectional buffering where explicit 3-state control is needed.

FAQ
What is the maximum input voltage the 7UL1T126FU,LF can tolerate?
The 7UL1T126FU,LF supports 3.6 V-tolerant inputs across its full operating temperature range (–40 °C to +125 °C), meaning it accepts logic-high signals up to 3.6 V regardless of VCC setting (2.3–3.6 V). This eliminates the need for external clamping diodes when interfacing with higher-voltage peripherals, and is explicitly confirmed in Section 2(5) and Absolute Maximum Ratings (VIN = –0.5 to 4.6 V).
Does the 7UL1T126FU,LF support bidirectional signal translation?
No, the 7UL1T126FU,LF is a unidirectional bus buffer: signal flows from input A to output Y only. Directionality is fixed; it does not auto-detect or switch direction like bidirectional translators (e.g., TXB010x). Its function is strictly non-inverting buffering with 3-state control via active-low enable (G), as defined in the Truth Table and Functional Description.
What is the purpose of the power-down protection feature in the 7UL1T126FU,LF?
The 7UL1T126FU,LF includes power-down protection that limits IOFF leakage current to ≤ ±80 µA at 125 °C when VCC = 0 V. This prevents back-driving of powered-down sections and avoids unintended current paths during hot-swap or partial-power-down scenarios - a requirement verified in Section 2(6) and Electrical Characteristics Table 9.3.
Can the 7UL1T126FU,LF operate reliably at 125 °C ambient temperature?
Yes, the 7UL1T126FU,LF is fully specified and tested for continuous operation from –40 °C to +125 °C. All DC and AC parameters - including VOH/VOL, propagation delay (≤ 5.2 ns), and IOFF leakage (≤ ±80 µA) - are guaranteed across this range per Sections 8 and 9.3–9.6, making it suitable for under-hood automotive and industrial control applications.
What package type and dimensions does the 7UL1T126FU,LF use?
The 7UL1T126FU,LF uses the USV (Ultra Small Outline) package: 5-pin, 1.2 mm × 0.8 mm body size, 0.4 mm lead pitch, and typical weight of 6.2 mg. Pin assignment and mechanical drawings are provided in Section 4 and Package Dimensions (Page 10) of the official Toshiba datasheet Rev. 3.0.A.
