Product details
Overview
74LV1T125GW-Q100 from Nexperia is a single-channel, automotive-grade level-translating buffer/line driver with 3-state output, supporting bidirectional voltage translation across 1.8 V, 2.5 V, 3.3 V, and 5.0 V CMOS logic domains. It features 5 V tolerant inputs, AEC-Q100 Grade 1 qualification (−40 °C to +125 °C), and operates with supply voltages from 1.6 V to 5.5 V. Used in signal interface bridging between mixed-voltage subsystems in automotive infotainment and body control modules.
For engineers reviewing the 74LV1T125GW-Q100 datasheet, 74LV1T125GW-Q100 pinout, 74LV1T125GW-Q100 application, or 74LV1T125GW-Q100 equivalent, key selection criteria include its single-supply up/down translation capability, 3-state enable control timing (tdis ≤ 7.3 ns at 5.0 V), 5 V input tolerance, and guaranteed operation over full automotive temperature range without external level-shifting components.
Technical Context
This device implements a single-buffer architecture with independent OE-controlled 3-state output, where output logic levels are referenced to VCC-not input voltage-enabling true level translation. Input thresholds scale with VCC (e.g., VIH = 0.65 × VCC min at 3.0 V), ensuring reliable recognition of lower-voltage signals (e.g., 1.8 V inputs at VCC = 3.3 V).
It supports both up-translation (1.8 V → 3.3 V) and down-translation (5.0 V → 3.3 V), enabled by 5 V tolerant inputs and rail-referenced CMOS output drive. Propagation delay is load- and voltage-dependent: tpd = 3.2 ns (typ) at VCC = 5.0 V, CL = 15 pF; disable time tdis = 5.0–7.3 ns across −40 °C to +125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.6 V to 5.5 V - enables direct interfacing with 1.8 V, 2.5 V, 3.3 V, and 5.0 V logic domains using one supply. |
| Input Voltage Tolerance | Up to 7.0 V - allows safe connection of 5 V signals into lower-VCC systems without clamping diodes or external protection. |
| Propagation Delay (tpd) | 3.2 ns (typ) at VCC = 5.0 V, CL = 15 pF - supports >50 MHz data rates in high-speed digital interconnects. |
| 3-State Disable Time (tdis) | 5.0–7.3 ns across −40 °C to +125 °C - ensures fast bus release for multi-drop shared-bus applications. |
| Operating Temperature | −40 °C to +125 °C - meets AEC-Q100 Grade 1 requirements for under-hood and cabin automotive electronics. |
| ESD Protection | HBM >2000 V, CDM >1000 V - provides robust handling during PCB assembly and system integration in production environments. |
| Output Drive Strength | ±25 mA - sufficient to drive 15–30 pF loads directly, eliminating need for external buffers in short-trace interfaces. |
Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package, 5-lead, 1.25 mm body width, 0.65 mm pitch, 1.1 mm height - optimized for space-constrained automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output enable input | Active-HIGH control: HIGH forces Y into high-impedance OFF-state; critical for bus arbitration and power-gated subsystems. |
| 2 (A) | Data input | 5 V tolerant; accepts 1.2 V–5.0 V logic levels regardless of VCC - enables flexible upstream signal sourcing. |
| 3 (GND) | Ground reference | 0 V return path for all internal circuitry and output current; must be low-inductance connection to minimize noise coupling. |
| 4 (Y) | Data output | CMOS rail-to-rail output referenced to VCC; drives 1.8 V–5.0 V logic thresholds depending on supply setting. |
| 5 (VCC) | Supply voltage | Single power rail defining output logic levels and input threshold scaling - eliminates dual-supply complexity in voltage translation. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply level translation | Eliminates need for dual-rail translators or discrete resistor networks - reduces BOM count and layout area in mixed-voltage ECUs. |
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C - supports deployment in engine control, ADAS sensor hubs, and gateway modules. |
| 5 V tolerant inputs | Accepts legacy 5 V microcontroller outputs while operating at 1.8 V or 2.5 V VCC - extends compatibility with older subsystems during platform migration. |
| Low ICC supply current | ≤10 μA typical at 1.8–5.0 V - minimizes quiescent power in always-on vehicle networks like LIN or CAN partial networking nodes. |
| Fast 3-state switching | ten ≤ 5.5 ns and tdis ≤ 7.3 ns at 5.0 V - prevents bus contention in time-critical multiplexed communication paths (e.g., shared debug or configuration buses). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar level-translating buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1T45DBVR | Bidirectional auto-sensing translation; requires direction control pin; max VCC = 5.5 V; no AEC-Q100 qualification. | Suitable for non-automotive portable devices; lacks guaranteed −40 °C to +125 °C operation and automotive reliability testing. | Select when bidirectional flow is required and automotive qualification is not mandatory. |
| TXB0101DCKR | Auto-direction sensing; 1.2 V–3.6 V VCCA/VCCB dual supply; no 5 V tolerant inputs; AEC-Q100 not claimed. | Designed for ultra-low-voltage IoT edge nodes; incompatible with 5 V signal sources or automotive temperature extremes. | Prefer for battery-powered wearables or industrial sensors where dual-supply flexibility outweighs automotive compliance. |
Compared with SN74LVC1T45DBVR and TXB0101DCKR, the 74LV1T125GW-Q100 uniquely delivers unidirectional 5 V tolerant translation with AEC-Q100 Grade 1 certification - making it the only option qualified for direct integration into safety-critical automotive signal paths requiring guaranteed operation at +125 °C and robust ESD/latch-up immunity.

FAQ
What is the maximum input voltage the 74LV1T125GW-Q100 can safely accept?
The device supports input voltages up to 7.0 V per Absolute Maximum Ratings, with 5 V tolerance explicitly guaranteed across all operating conditions. This allows direct connection of 5 V logic signals even when VCC is set to 1.8 V or 2.5 V, eliminating external clamping components in mixed-voltage automotive designs.
Does the 74LV1T125GW-Q100 support bidirectional level translation?
No - it is a unidirectional buffer: signal flows only from input A to output Y. Directionality is fixed; the device does not auto-detect or switch direction. For bidirectional applications, separate devices or dedicated bidirectional translators (e.g., TXB0101) are required, though those lack AEC-Q100 Grade 1 qualification.
How does the 3-state output behave when OE is HIGH?
When OE is driven HIGH, the Y output enters a high-impedance OFF-state (Z), electrically disconnecting the output from the bus. This behavior is fully characterized across −40 °C to +125 °C, with IOZ ≤ ±2.5 μA, ensuring minimal leakage and clean bus release in multi-driver configurations such as shared diagnostic or configuration lines.
Can the 74LV1T125GW-Q100 operate at 1.6 V VCC while driving a 3.3 V logic load?
No - output voltage levels are strictly referenced to VCC. At VCC = 1.6 V, the VOH is ~1.21 V (min), insufficient to meet 3.3 V logic HIGH thresholds. To drive a 3.3 V load, VCC must be set to 3.3 V (or 5.0 V), enabling VOH ≥ 2.8 V - confirming its role as a *supply-defined* translator, not a fixed-output voltage shifter.
