Product details
Overview
NLVVHCT125ADTRG from onsemi is an automotive-grade quad bus buffer with 3-state control inputs, fabricated in silicon gate CMOS technology. It delivers TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2.0 V), 3.8 ns typical propagation delay at 5.0 V, full 5.0 V CMOS output swing, and operates across 2.0–5.5 V supply range. It serves as a level-shifting interface between 3.3 V and 5.0 V systems in engine control units and body electronics.
For engineers reviewing the NLVVHCT125ADTRG datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, TSSOP-14 package, 3-state enable logic (active-low OE), ±8 mA drive capability, and input tolerance up to 7.0 V - critical for hot-swap and mixed-voltage automotive signal routing.
Technical Context
The NLVVHCT125ADTRG implements four independent non-inverting buffers, each with a dedicated active-low 3-state enable (OE) input. Its input structure tolerates voltages from −0.5 V to +7.0 V regardless of VCC, enabling robust interfacing between 3.0 V and 5.0 V domains without external level shifters.
Internally, it uses three-stage buffering to ensure high noise immunity and balanced propagation delays. The output stage provides controlled rise/fall times and supports hot insertion via power-down protection - outputs remain safe even when VCC = 0 V, and inputs are protected against supply–input mismatch during battery backup or system wake-up events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - enables operation in both 3.3 V and 5.0 V automotive subsystems without voltage translation. |
| Propagation Delay (tPD) | 3.8 ns (typ) at VCC = 5.0 V, CL = 15 pF - supports high-speed data routing in CAN/LIN gateway interfaces. |
| Output Drive Strength | ±8.0 mA at VCC = 4.5 V - sufficient to drive multiple TTL loads or 50 pF traces in distributed ECUs. |
| Input Voltage Tolerance | −0.5 V to +7.0 V - prevents damage during load dump transients or cross-supply probing in vehicle harness testing. |
| Quiescent Supply Current | 4.0 µA (max) at TA = 25°C - ensures low static power in always-on vehicle modules like door controllers. |
| ESD Rating | HBM > 2000 V, MM > 200 V - meets baseline requirements for assembly handling and in-vehicle ESD robustness. |
| Operating Temperature | −55°C to +125°C - qualified for under-hood and transmission control applications per AEC-Q100 Grade 1. |
Pinout & Package
TSSOP-14 (DT suffix, Case 948G), Pb-free, RoHS compliant, 4.4 mm × 5.0 mm footprint with 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | Data Input (A1–A4) | Non-inverting buffer inputs; accept TTL- or CMOS-level signals; tolerate up to 7.0 V. |
| 2, 5, 11, 14 | 3-State Enable (OE1–OE4) | Active-low controls; OE = HIGH forces output into high-impedance state - essential for bus arbitration. |
| 3, 6, 8, 12 | Buffer Output (Y1–Y4) | CMOS-compatible outputs with rail-to-rail swing; drive capability ±8 mA; support hot insertion. |
| 7 | GND | Ground reference for all I/O and internal logic; must be low-impedance connection in automotive PCB layout. |
| 14 | VCC | Primary power supply pin; decoupling capacitor (100 nF) required within 5 mm for noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-Compatible Inputs | VIL = 0.8 V / VIH = 2.0 V - allows direct connection to legacy 5 V microcontrollers without pull-ups or translators. |
| Wide Supply Range | 2.0 V to 5.5 V operation - supports dual-rail designs and brown-out resilience in 12 V vehicle electrical systems. |
| Input/Output Protection | Inputs withstand −0.5 V to +7.0 V; outputs safe at VCC = 0 V - eliminates need for external clamping diodes in body control modules. |
| AEC-Q100 Qualified | NLV prefix indicates automotive qualification, PPAP capability, and unique site/control change tracking - required for Tier 1 production release. |
| Low Dynamic Noise | VOLP ≤ 0.8 V (max) - minimizes ground bounce in multi-buffer fanout configurations on shared PCB planes. |
Applications
| Engine Control Unit (ECU) Signal Conditioning | Body Control Module (BCM) Bus Isolation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74VHCT125ADTRG | Same die, non-automotive grade; lacks NLV prefix, AEC-Q100 qualification, and PPAP documentation. | Approved for industrial/commercial use only; not accepted in OEM automotive BOMs requiring PPAP submission. | Select when cost sensitivity outweighs automotive compliance requirements and temperature range ≤ 85°C suffices. |
| SN74LVC125APW | 3.3 V only (1.65–3.6 V); lower drive (±24 mA); no 7.0 V input tolerance; different pinout (SOIC-14 vs TSSOP-14). | Suitable for 3.3 V-only systems; requires redesign if interfacing to 5 V buses or surviving load dump events. | Choose for new 3.3 V designs where board space allows SOIC-14 and automotive qualification is unnecessary. |
Compared with MC74VHCT125ADTRG, NLVVHCT125ADTRG adds AEC-Q100 Grade 1 validation and traceable automotive change control, while SN74LVC125APW offers higher drive but sacrifices mixed-voltage interoperability and automotive qualification - making NLVVHCT125ADTRG the sole drop-in solution for legacy 5 V automotive signal routing upgrades.

FAQ
What is the operating temperature range for NLVVHCT125ADTRG?
The NLVVHCT125ADTRG is rated for −55°C to +125°C operation and is AEC-Q100 qualified for automotive Grade 1 applications. This range covers under-hood environments such as engine control units and transmission control modules. The device maintains specified DC and AC performance across this full range, with derating applied above 65°C per the TSSOP package thermal limits. NLVVHCT125ADTRG's design ensures stable timing and logic integrity even during rapid thermal cycling in vehicle start-stop cycles.
Is NLVVHCT125ADTRG pin-compatible with standard 74-series logic devices?
Yes, NLVVHCT125ADTRG is pin- and function-compatible with industry-standard 74HCT125 and 74VHCT125 devices in TSSOP-14 packages. Its pinout matches the JEDEC MS-012 standard: inputs (A1–A4) and enables (OE1–OE4) occupy alternating positions, with outputs (Y1–Y4), VCC, and GND placed identically. This allows direct replacement in existing layouts without PCB revision - provided the original design used TSSOP-14 and accounted for the NLV prefix's automotive qualification requirements.
Does NLVVHCT125ADTRG support hot insertion?
Yes, NLVVHCT125ADTRG supports hot insertion due to its powered-off output protection: outputs remain safe even when VCC = 0 V, and inputs tolerate −0.5 V to +7.0 V regardless of supply state. This behavior is confirmed in the datasheet's "Power Down Protection" feature and Maximum Ratings table. In practice, NLVVHCT125ADTRG can be safely inserted into a live 5 V backplane or module connector without damaging itself or upstream circuitry - a key requirement for serviceable automotive subassemblies like infotainment head units or ADAS camera modules.
What is the maximum output drive capability of NLVVHCT125ADTRG?
NLVVHCT125ADTRG delivers ±8.0 mA output drive per channel at VCC = 4.5 V, as specified in the DC Electrical Characteristics table under VOL and VOH test conditions. This enables driving multiple TTL loads (e.g., 10x 74HCT inputs) or 50 pF transmission lines typical in automotive wiring harnesses. The device maintains this drive strength across −55°C to +125°C, with VOL ≤ 0.52 V and VOH ≥ 2.34 V under worst-case conditions - ensuring noise margin preservation in electrically noisy vehicle environments.
How does NLVVHCT125ADTRG handle voltage level translation between 3.3 V and 5.0 V systems?
NLVVHCT125ADTRG performs bidirectional level translation via its TTL-compatible inputs and full 5.0 V CMOS output swing. Inputs recognize 3.3 V logic highs (VIH = 2.0 V min) and provide rail-to-rail 5.0 V outputs, enabling 3.3 V MCUs to drive 5.0 V peripherals. Its input tolerance up to 7.0 V also allows reverse-direction interfacing - e.g., 5.0 V sensors feeding 3.3 V processors - without external components. This capability is explicitly documented in the datasheet's "level converter" application note and verified across recommended operating conditions.
