Product details
Overview
74LV1T126GW-Q100 from Nexperia is a single-channel, automotive-grade level-translating buffer/line driver with 3-state output, supporting bidirectional voltage translation (1.8 V ↔ 3.3 V, 2.5 V ↔ 5.0 V), 5 V tolerant inputs, and operation across 1.6 V to 5.5 V supply range. It enables logic-level bridging between mixed-voltage subsystems in automotive body control modules and infotainment interfaces.
For engineers reviewing the 74LV1T126GW-Q100 datasheet, 74LV1T126GW-Q100 pinout, 74LV1T126GW-Q100 application, or 74LV1T126GW-Q100 equivalent, this device serves as a compact, AEC-Q100 Grade 1 qualified solution for voltage domain isolation, bus driving with enable-controlled high-impedance state, and low-power signal conditioning in space-constrained automotive PCBs.
Technical Context
This IC implements a single non-inverting buffer with active-low 3-state output enable (OE), where output logic levels are referenced to VCC and input thresholds scale dynamically with supply voltage. Its architecture supports both up-translation (e.g., 1.8 V input → 3.3 V output at VCC = 3.3 V) and down-translation (e.g., 5.0 V input → 3.3 V output at VCC = 3.3 V).
Input pins tolerate up to 7.0 V independent of VCC, enabling safe interfacing with higher-voltage logic domains. The device operates across -40 °C to +125 °C ambient, with static and dynamic parameters fully characterized over that full range, including propagation delays as low as 3.2 ns (VCC = 5.0 V, CL = 15 pF) and disable time under 6.8 ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.6 V to 5.5 V - Enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5.0 V logic domains without external level shifters. |
| Input Voltage Tolerance | Up to 7.0 V - Allows safe connection to 5 V systems while powered from lower VCC (e.g., 2.5 V or 3.3 V), eliminating need for external clamping. |
| tpd (A→Y) | 3.2 ns typical at VCC = 5.0 V, CL = 15 pF - Supports >50 MHz signal integrity in high-speed digital interconnects such as sensor-to-ECU links. |
| IOZ (OFF-state current) | ±2.5 μA max at -40 °C to +125 °C - Ensures minimal leakage into downstream circuits during 3-state disable, critical for low-power sleep modes. |
| Ambient Temp Range | -40 °C to +125 °C - Qualified per AEC-Q100 Grade 1, meeting thermal requirements for under-hood and cabin-mounted automotive electronics. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Provides robust handling tolerance during SMT assembly and field service in automotive manufacturing environments. |
| ICC (Supply Current) | 10 μA max per input pin at VCC = 5.0 V - Delivers ultra-low static power for always-on vehicle networks like LIN or wake-up monitoring circuits. |
Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package: 5-lead, 1.25 mm body width, 0.65 mm lead pitch, 1.1 mm height - optimized for high-density automotive PCB layouts with reflow-compatible footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output enable input (active LOW) | Drives Y to high-impedance when LOW; enables bidirectional bus sharing and power-gated subsystem isolation. |
| 2 (A) | Data input | Accepts 1.2 V–5.0 V logic signals; threshold scales with VCC to support multi-supply domain interfacing. |
| 3 (GND) | Ground reference | 0 V return path for all internal circuitry; must be low-impedance to maintain noise immunity in automotive EMI environments. |
| 4 (Y) | 3-state buffered output | CMOS-compatible output referenced to VCC; sinks/source up to ±25 mA; transitions cleanly between driven and Hi-Z states. |
| 5 (VCC) | Supply voltage | Single supply powering internal logic and output stage; defines output voltage swing and input threshold levels. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply level translation | Eliminates need for dual-rail translators or discrete resistor-divider networks in mixed-voltage automotive subsystems. |
| 5 V tolerant inputs | Permits direct connection to legacy 5 V microcontrollers or sensors without external protection diodes or voltage dividers. |
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C, including latch-up immunity (>250 mA) and extended life testing. |
| Low dynamic power (CPD = 11.6 pF at 5 V) | Reduces switching power dissipation in high-frequency data paths such as CAN transceiver control lines or display interface buffers. |
| Fast enable/disable timing (ten ≤ 5.5 ns, tdis ≤ 6.8 ns) | Enables precise temporal control of bus arbitration and reduces signal contention windows in shared communication lines. |
Applications
| Body Control Module (BCM) Signal Conditioning | Infotainment System Voltage Bridging |

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 | Direction control pin instead of OE; dual-supply (VCCA/VCCB); no AEC-Q100 qualification. | Requires two supplies and lacks automotive temperature/qualification coverage; suited for industrial PC designs only. | Select only if bidirectional translation and dual-rail flexibility outweigh automotive compliance needs. |
| TXS0101DCKR | Auto-direction sensing; open-drain outputs; no 3-state control; higher ICC (20 μA typical vs. 10 μA). | Not suitable for push-pull bus driving or deterministic OE timing; limited to I²C/SMBus-style open-drain protocols. | Choose only for low-speed, bidirectional, open-drain applications where automatic direction detection is required. |
Compared with SN74LVC1T45DBVR and TXS0101DCKR, the 74LV1T126GW-Q100 uniquely combines AEC-Q100 Grade 1 qualification, single-supply operation, deterministic 3-state control, and 5 V tolerant inputs-making it the only drop-in solution for safety-critical, space-constrained automotive signal bridging where supply count, qualification, and timing predictability are non-negotiable.

FAQ
What is the maximum input voltage the 74LV1T126GW-Q100 can safely accept?
The device accepts input voltages up to 7.0 V regardless of VCC level, as confirmed in Table 5 (Limiting Values). This 5 V tolerance allows direct interfacing with legacy 5 V logic without external protection, provided VI remains within -0.5 V to +7.0 V and current limits are observed.
Does the 74LV1T126GW-Q100 support true bidirectional level translation?
No-it is a unidirectional buffer (A → Y) with 3-state output control. Bidirectional translation requires separate devices per direction or a dedicated auto-sensing translator like TXS0101. Its OE pin enables bus sharing but does not reverse signal flow.
Can this device operate reliably at 1.6 V supply voltage?
Yes. Per Table 6, VCC min is 1.6 V across the full -40 °C to +125 °C range. Static and dynamic parameters-including VIH/VIL thresholds and tpd-are specified down to 1.65 V, confirming functional operation at 1.6 V with appropriate timing margin.
Is the 74LV1T126GW-Q100 pin-compatible with standard 74LVC1G126 variants?
No. While functionally similar, it uses the TSSOP5 (SOT353-1) 5-lead package with pin 1 = OE, pin 2 = A, pin 3 = GND, pin 4 = Y, pin 5 = VCC-distinct from SC-70 or SOT363 packages used by many LVC variants, requiring PCB layout adaptation.
