Product details
Overview
NLU1GT126AMX1TCG from onsemi is a single-channel, non-inverting 3-state buffer IC with TTL-compatible inputs and full 5.0 V CMOS output swing, designed for high-speed signal routing in space-constrained applications. It features 3.8 ns typical propagation delay at 5.0 V, ±12.5 mA output drive, and operates across −55 °C to +125 °C. Used in low-power logic interfacing between mixed-voltage domains.
For engineers reviewing the NLU1GT126AMX1TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its UDFN6-1.45×1.0 mm package, OE-controlled 3-state operation, LSTTL input compatibility, and robust 7.0 V overvoltage tolerance on I/O pins.
Technical Context
The NLU1GT126AMX1TCG implements a single CMOS-based non-inverting buffer with active-low 3-state enable (OE), requiring OE = Low to assert high-impedance output. Its input structure accepts TTL-level thresholds (VIL = 0.8 V, VIH = 2.0 V) while delivering rail-to-rail CMOS outputs (VOH > 0.8 VCC, VOL < 0.1 VCC).
Input and output pins are protected against overvoltage up to 7.0 V independent of VCC, enabling safe hot-swap and level-shifting use cases. Propagation delays (tPLH/tPHL) and enable/disable timing (tPZL/tPLZ) are characterized across 1.65–5.5 V supply range and full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports dual-supply systems and battery-backed logic interfaces |
| Propagation Delay (Typ) | 3.8 ns @ VCC = 5.0 V, CL = 15 pF - enables sub-260 MHz signal routing without timing closure issues |
| Output Drive | ±12.5 mA - sufficient to drive 50 pF loads or multiple standard CMOS inputs |
| Input Thresholds | VIL = 0.8 V, VIH = 2.0 V - ensures reliable recognition of legacy TTL signals at 5 V |
| I/O Overvoltage Tolerance | −0.5 V to +7.0 V - allows safe connection to unpowered or higher-voltage subsystems |
| Operating Temperature | −55 °C to +125 °C - qualified for automotive under-hood and industrial control environments |
| Power Dissipation (Max) | 20 µA ICC @ TA = 25 °C - enables ultra-low static power in always-on monitoring circuits |

Package: UDFN6 (1.45 mm × 1.0 mm × 0.50 mm, 0.5 mm pitch), case 517AQ, Pb-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GND | Ground reference | Primary return path for all internal logic and I/O current; must be low-impedance to minimize noise coupling |
| 2 - OE | Active-low 3-state enable | Drives output Y to high-impedance when Low; tied High to enable buffer function |
| 3 - IN A | Non-inverting data input | Accepts TTL/CMOS logic levels; internally clamped to support 7.0 V tolerant operation |
| 4 - NC | No connect | Internally unconnected; must remain floating or grounded per layout guidelines - no external connection |
| 5 - OUT Y | Buffered non-inverting output | Delivers full CMOS swing (0–VCC); high-impedance when OE = Low; rated for ±12.5 mA sink/source |
| 6 - VCC | Positive supply | Supplies core logic and output drivers; bypass capacitor (0.1 µF) required within 2 mm of this pin |
Key Features

FAQ
What is the recommended operating voltage range for the NLU1GT126AMX1TCG?
The NLU1GT126AMX1TCG operates reliably from 1.65 V to 5.5 V DC supply voltage. This wide range supports both 3.3 V and 5.0 V system domains, and enables use in battery-powered devices with varying discharge profiles. The device maintains specified timing and drive performance across this entire range, as validated in the AC Electrical Characteristics table of the official datasheet.
Does the NLU1GT126AMX1TCG support true 5 V TTL input compatibility?
Yes, the NLU1GT126AMX1TCG features LSTTL-compatible inputs with guaranteed VIL ≤ 0.8 V and VIH ≥ 2.0 V at VCC = 4.5–5.5 V, ensuring reliable recognition of standard 5 V TTL logic levels. This eliminates the need for external biasing or level translation when interfacing with legacy 5 V logic families.
Can the NLU1GT126AMX1TCG be used in hot-swap or partial-power-down scenarios?
Yes, the NLU1GT126AMX1TCG provides input and output structures rated for −0.5 V to +7.0 V regardless of VCC state, enabling safe operation during hot-swap or partial power-down conditions. This overvoltage tolerance is explicitly verified per JEDEC JESD78 latch-up testing and does not require external protection components.
What is the thermal performance rating of the NLU1GT126AMX1TCG?
The NLU1GT126AMX1TCG is rated for continuous operation from −55 °C to +125 °C ambient temperature, with junction temperature limited to 150 °C. Its UDFN6 package exhibits low thermal resistance, and the device meets MSL Level 1 moisture sensitivity - allowing standard reflow without baking for most assembly processes.
Is the NLU1GT126AMX1TCG pin-compatible with other MiniGate buffers?
No - the NLU1GT126AMX1TCG uses a dedicated 6-pin UDFN6 layout (case 517AQ) with specific pin assignment (GND, OE, IN A, NC, OUT Y, VCC). Other MiniGate variants like NLU1GT125 or NLU1GT132 have different logic functions and distinct pinouts; direct substitution requires schematic and layout review.
