Product details
Overview
NLU1GT125AMX1TCG 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 level translation and bus isolation in space-constrained digital systems. It operates from 1.65 V to 5.5 V, delivers 3.8 ns typical propagation delay at 5.0 V, supports ±12.5 mA output drive, and features input/output overvoltage tolerance up to 7.0 V independent of supply voltage.
For engineers reviewing the NLU1GT125AMX1TCG datasheet, pinout, applications, or equivalent options, key selection considerations include its UDFN6 (1.45 × 1.0 mm) ultra-small footprint, OE-controlled 3-state output behavior, LSTTL-compatible input thresholds (VIL = 0.8 V, VIH = 2.0 V), and automotive-grade qualification under AEC-Q100.
Technical Context
The NLU1GT125AMX1TCG implements a single CMOS-based non-inverting buffer with active-high 3-state enable (OE). Its input structure accepts TTL-level logic while driving full-rail CMOS outputs, enabling interoperability between legacy TTL and modern low-voltage CMOS domains. Input and output pins are protected against overvoltage up to 7.0 V regardless of VCC setting.
Propagation delay (tPLH/tPHL) is specified down to 3.8 ns (typ) at VCC = 5.0 V with CL = 15 pF, and output enable/disable timing (tPZL/tPLZ) is tightly balanced at 3.6–4.8 ns (typ). The device uses a rail-to-rail output stage capable of sourcing/sinking ±12.5 mA while maintaining VOH > 0.8 VCC and VOL < 0.1 VCC under load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports mixed-voltage system interfacing including 1.8 V, 3.3 V, and 5.0 V logic domains |
| tPD (Typ) | 3.8 ns @ VCC = 5.0 V, CL = 15 pF - enables high-speed data routing in compact timing-critical paths |
| IO Max | ±12.5 mA - sufficient to drive standard CMOS loads and short PCB traces without external buffering |
| VIN Tolerance | −0.5 V to +7.0 V - allows safe operation during hot-swap, power sequencing, or transient overvoltage events |
| VIH / VIL | 2.0 V / 0.8 V @ VCC ≥ 4.5 V - ensures reliable recognition of LSTTL input signals across temperature |
| Package | UDFN6 (1.45 × 1.0 mm, 0.5 mm pitch) - provides minimal PCB area occupancy for portable and dense embedded designs |
Pinout & Package
Package: UDFN6 (1.45 mm × 1.0 mm, 0.5 mm pitch), exposed thermal pad, lead-free, RoHS-compliant. Compliant with MSL Level 1 moisture sensitivity rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry and output stage return path |
| 2 | OE | Active-high 3-state enable input - drives output to high-impedance when low |
| 3 | IN A | Non-inverting digital input - accepts TTL-compatible logic levels |
| 4 | NC | No connect - internally unconnected; must be left floating or tied to GND per layout guidelines |
| 5 | OUT Y | Buffered non-inverting output - delivers full CMOS swing with ±12.5 mA drive capability |
| 6 | VCC | Positive supply input - powers internal logic and output stage; decoupling capacitor required |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-inverting 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | Same 1.65–5.5 V VCC range, but 3.5 ns tPD (typ) at 3.3 V; no 7 V overvoltage tolerance; SOT-23-5 package (larger than UDFN6) | Lacks automotive qualification and overvoltage protection; suitable only for benign commercial environments | Select when cost is primary and board space is less constrained; verify absence of voltage transients in target system |
| 74LVC1G125GW,125 | Identical logic function and VCC range; 3.9 ns tPD (typ); 7 V I/O tolerance supported; XSON6 (1.2 × 1.0 mm) package - slightly smaller footprint than NLU1GT125AMX1TCG's 1.45 × 1.0 mm | Not AEC-Q100 qualified; rated for −40 °C to +125 °C but lacks PPAP documentation | Prefer for space-optimized industrial designs where automotive compliance is not required |
Compared with SN74LVC1G125DBVR and 74LVC1G125GW,125, the NLU1GT125AMX1TCG uniquely combines AEC-Q100 qualification, 7.0 V overvoltage tolerance, and UDFN6 packaging - making it the only option qualified for automotive body electronics with transient-hardened I/O in sub-1.5 mm² area.

FAQ
What is the maximum operating temperature range for the NLU1GT125AMX1TCG?
The NLU1GT125AMX1TCG is rated for operation from −55 °C to +125 °C. This extended temperature range supports deployment in harsh environments such as under-hood automotive systems, industrial motor controls, and outdoor sensor enclosures. The device maintains specified DC and AC electrical characteristics across this full range, with parameters like VOH, VOL, and tPD validated at both extremes per the official datasheet.
Does the NLU1GT125AMX1TCG support 1.8 V logic levels?
Yes, the NLU1GT125AMX1TCG supports 1.8 V logic levels. Its recommended VCC range includes 1.65 V to 5.5 V, and input thresholds scale accordingly - for example, VIH is guaranteed ≥ 0.65 × VCC and VIL ≤ 0.35 × VCC at VCC = 1.8 V. The NLU1GT125AMX1TCG reliably interfaces with 1.8 V microcontrollers while delivering full 1.8 V CMOS output swing.
Is the NLU1GT125AMX1TCG pin-compatible with other MiniGate buffers?
No, the NLU1GT125AMX1TCG is not pin-compatible with other MiniGate variants such as NLU1GT04 or NLU1GT32. Each MiniGate device has unique pin assignments optimized for its specific logic function. The NLU1GT125AMX1TCG uses a fixed 6-pin UDFN layout with dedicated GND, OE, IN A, NC, OUT Y, and VCC terminals - confirmed in Figure 1 and PIN ASSIGNMENT table of the datasheet.
What is the purpose of the NC pin on the NLU1GT125AMX1TCG?
The NC (No Connect) pin on the NLU1GT125AMX1TCG is internally unconnected and serves no electrical function. Per the datasheet, it must be left floating or tied to GND in PCB layout to avoid parasitic coupling; it is not intended for thermal relief or mechanical anchoring. This pin exists solely for package symmetry and does not affect device operation or timing performance of the NLU1GT125AMX1TCG.
How does the NLU1GT125AMX1TCG handle power-down conditions?
The NLU1GT125AMX1TCG provides built-in power-down protection on all inputs, meaning inputs remain high-impedance and non-destructive even when VCC = 0 V - as long as applied input voltages stay within −0.5 V to +7.0 V. This allows safe "live" signal injection during power sequencing or brown-out conditions without damaging the NLU1GT125AMX1TCG or pulling current from unpowered rails.
