Product details
Overview
NLVVHC1G126DFT1G from onsemi is a single-channel noninverting 3-state buffer IC designed for level-shifting and bus isolation in mixed-voltage systems. It operates from 2.0 V to 5.5 V, delivers 3.5 ns typical propagation delay at 5 V, supports ±8 mA output drive at 3.0 V, and features overvoltage-tolerant inputs/outputs up to 5.5 V - enabling reliable interfacing between 3 V and 5 V logic domains in industrial control modules.
For engineers reviewing the NLVVHC1G126DFT1G datasheet, pinout, applications, or equivalent options, key selection criteria include its CMOS-level input thresholds, IOFF partial power-down protection, SC-88A package footprint, and guaranteed operation across −55 °C to +125 °C for automotive and harsh-environment embedded designs.
Technical Context
The NLVVHC1G126DFT1G implements a three-stage buffered architecture with a high-noise-immunity 3-state output stage. Its input structures tolerate voltages up to 5.5 V independent of VCC, allowing safe 5 V-to-3 V bidirectional interfacing without external clamping.
It incorporates IOFF circuitry that disables I/O leakage when VCC = 0 V, preventing back-powering of powered-down subsystems during hot insertion or battery-backup scenarios. Output structures also withstand VOUT > VCC and survive VCC = 0 V conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports direct integration into both 3.3 V and 5 V supply rails without level translators. |
| tPD (typ) | 3.5 ns at VCC = 5 V, CL = 15 pF - enables high-speed data buffering in timing-critical digital interfaces. |
| IOH/IOL | ±8 mA at VCC = 3.0 V - drives standard TTL/CMOS loads and multiple gate inputs without fanout limitation. |
| Input Thresholds | CMOS-level (VIH = 70% VCC, VIL = 30% VCC) - ensures noise margin compatibility with modern low-voltage logic families. |
| Overvoltage Tolerance | Inputs/outputs rated to 5.5 V regardless of VCC - eliminates need for external protection diodes in mixed-supply systems. |
| IOFF Leakage | ≤10 µA at VCC = 0 V - prevents current backflow into unpowered sections during partial power-down sequences. |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive, industrial motor control, and extended-temperature instrumentation. |
Pinout & Package
NLVVHC1G126DFT1G is packaged in SC-88A (Case 419A), a 5-pin surface-mount package measuring 2.1 mm × 1.25 mm × 0.95 mm with 0.65 mm pitch. Pin 1 is marked by a dot or beveled edge per JEDEC MO-203-DA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output Enable | Active-high control: drives Y to high-impedance when low; enables noninverting pass-through when high. |
| 2 (A) | Data Input | CMOS-level input accepting 0–5.5 V signals; internally protected against overvoltage and ESD. |
| 3 (GND) | Ground Reference | Primary return path for all internal logic and I/O currents; must be low-impedance for noise immunity. |
| 4 (Y) | Buffered Output | Noninverting 3-state output with ±8 mA drive strength; tri-states when OE = low. |
| 5 (VCC) | Supply Voltage | Power rail for internal logic and output stage; accepts 2.0–5.5 V; decoupling capacitor required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 2.0 V to 5.5 V operation - eliminates separate voltage translators in multi-rail PCBs. |
| Overvoltage-tolerant I/O | 5.5 V max input/output voltage regardless of VCC - enables robust 5 V ↔ 3 V interface without external components. |
| IOFF partial power-down | Sub-10 µA leakage when VCC = 0 V - prevents unintended powering of downstream circuits during sleep modes. |
| High noise immunity | Three-stage buffered output design - suppresses ground bounce and crosstalk in dense routing environments. |
| AEC-Q100 qualified | Automotive-grade reliability with PPAP capability - validated for use in engine control units and ADAS sensor hubs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar noninverting 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74VHC1GT126DFT1G | TTL-level input thresholds (VIH = 2.0 V fixed), otherwise identical AC/DC specs and SC-88A packaging. | Better suited for legacy 5 V TTL source interfacing where CMOS threshold matching is unnecessary. | Select when driving from standard 5 V TTL outputs; avoid if interfacing with modern low-VTH MCUs. |
| SN74LVC1G126DBVR | Lower VCC min (1.65 V), higher speed (2.5 ns tPD), but only rated to 125 °C (not −55 °C). | Limited to commercial/industrial temp range; lacks AEC-Q100 qualification and extended cold-start support. | Prefer for cost-sensitive consumer electronics; avoid for automotive or extended-temperature deployments. |
Compared with MC74VHC1GT126DFT1G and SN74LVC1G126DBVR, NLVVHC1G126DFT1G uniquely combines −55 °C to +125 °C operation, CMOS-input compatibility, and AEC-Q100 qualification - making it the only choice for automotive body controllers requiring guaranteed startup below −40 °C and long-term reliability in under-hood thermal cycling.

FAQ
What is the maximum input voltage rating for NLVVHC1G126DFT1G?
NLVVHC1G126DFT1G supports DC input voltages up to 5.5 V regardless of VCC level - a key feature enabling safe interfacing between 5 V and lower-voltage logic domains without external clamping diodes. This overvoltage tolerance is verified across all operating temperatures and applies to both A and OE pins per the onsemi datasheet Absolute Maximum Ratings table.
Does NLVVHC1G126DFT1G support partial power-down operation?
Yes, NLVVHC1G126DFT1G includes IOFF circuitry that limits input/output leakage to ≤10 µA when VCC = 0 V. This prevents back-powering of unpowered system sections during hot insertion or battery-backed sleep states - a requirement explicitly validated in the datasheet's DC Electrical Characteristics section under IOFF parameter testing.
What is the propagation delay of NLVVHC1G126DFT1G at 3.3 V supply?
At VCC = 3.3 V and CL = 15 pF, NLVVHC1G126DFT1G exhibits a typical propagation delay (tPLH/tPHL) of 4.5 ns, with a maximum of 8.0 ns over −40 °C to +85 °C and 12.0 ns over the full −55 °C to +125 °C range. These values are specified in the AC Electrical Characteristics table of the official onsemi datasheet.
Is NLVVHC1G126DFT1G pin-compatible with other SC-88A logic buffers?
NLVVHC1G126DFT1G uses the standard SC-88A pinout (OE-A-GND-Y-VCC), matching industry-standard 5-pin logic buffers like SN74LVC1G126 and MC74VHC1GT126 variants. However, pin compatibility does not guarantee functional equivalence - input threshold type (CMOS vs. TTL) and temperature range differ between part numbers.
What package variant is used for NLVVHC1G126DFT1G?
NLVVHC1G126DFT1G is supplied in the SC-88A package (JEDEC case number 419A), a 5-pin, 2.1 mm × 1.25 mm surface-mount outline with 0.65 mm lead pitch. This compact footprint is confirmed in the Ordering Information table on page 8 of the onsemi datasheet and matches the marking diagram labeled "DF SUFFIX".
