Product details
Overview
NLVLCX125DTR2G from onsemi is a low-voltage CMOS quad non-inverting buffer with 3-state outputs and 5 V-tolerant inputs/outputs, operating from 1.65 V to 5.5 V supply. It delivers ±24 mA output drive at 3.0 V, supports live insertion/withdrawal, features IOFF protection for high-impedance state when VCC = 0 V, and is qualified for automotive applications per AEC-Q100. It is used in memory address driving and TTL-level bus transceiver systems.
For engineers reviewing the NLVLCX125DTR2G datasheet, pinout, applications, or equivalent options, key selection criteria include 5 V tolerance on all I/O pins, 14-pin TSSOP package compatibility, sub-6 ns propagation delay at 3.3 V, 10 µA quiescent ICC, and guaranteed tri-state enable/disable timing under −40 °C to +125 °C operation.
Technical Context
The NLVLCX125DTR2G implements four independent non-inverting buffers, each with dedicated active-high Output Enable (OEn) control enabling individual 3-state output management. Its input structure supports LVTTL and LVCMOS logic families while maintaining 5.5 V absolute maximum input voltage rating.
It uses advanced CMOS process technology to achieve near-zero static supply current across all logic states and latchup immunity exceeding 100 mA. The device meets ESD HBM >2000 V and supports hot-plug operation via IOFF specification that forces high-impedance outputs even when VCC is unpowered.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables direct interface between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| Input Voltage Tolerance | −0.5 V to +6.5 V - Allows safe connection to legacy 5 V TTL outputs without clamping diodes or external protection. |
| Propagation Delay (tPLH/tPHL) | 4.7 ns max at 4.5–5.5 V - Ensures tight timing margins in high-speed address/data bus applications up to ~210 MHz toggle rate. |
| Output Drive Strength | ±24 mA at 3.0 V - Sustains robust signal integrity across 50 Ω transmission lines or multiple TTL loads. |
| Quiescent Supply Current | 10 µA max - Reduces system-level standby power in battery-backed or always-on embedded controllers. |
| Operating Temperature | −40 °C to +125 °C - Validated for under-hood automotive, industrial motor control, and outdoor telecom equipment. |
| IOFF Leakage | 10 µA max when VCC = 0 V - Prevents back-powering of powered subsystems during hot-swap or partial power-down sequences. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | OEn (Output Enable n) | Active-high control per buffer channel; HIGH disables output into high-impedance state, critical for bus arbitration. |
| 2, 5, 9, 12 | Dn (Data Input n) | Non-inverting input for corresponding buffer; accepts 1.65–5.5 V logic levels with 5 V tolerance. |
| 3, 6, 8, 11 | On (Output n) | 3-state buffered output; drives HIGH/LOW or enters Hi-Z based on OEn; supports parallel bus loading. |
| 7 | GND | Ground reference for all logic and I/O; must be connected to system ground plane for noise immunity. |
| 14 | VCC | Primary power supply; decoupling capacitor (0.1 µF ceramic) required within 5 mm for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V-tolerant I/O | Enables mixed-voltage system integration without external level translators, reducing BOM count and board area. |
| Live insertion support | IOFF specification ensures outputs remain high-impedance during hot-plug events, preventing bus contention or damage. |
| Balanced ±24 mA drive | Eliminates need for external pull-up/pull-down resistors in open-drain or bus-termination configurations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74LCX125DR2G | Same die, SOIC-14 package (Case 751A); 1.27 mm pitch vs. TSSOP's 0.65 mm; higher thermal resistance (116 °C/W vs. 150 °C/W). | Suitable for through-hole prototyping or legacy PCBs with SOIC footprints; less space-constrained designs. | Select when board layout uses SOIC-14 land pattern or requires easier hand-soldering. |
| SN74LVC125APWR | TI part; identical function but different AC specs: tPLH/tPHL = 5.1 ns max at 3.3 V (vs. 6.0 ns for NLVLCX125DTR2G); IOFF not specified. | Better suited for 3.3 V-only systems needing marginally faster timing; lacks AEC-Q100 qualification and explicit IOFF guarantee. | Choose for cost-sensitive consumer applications where automotive qualification and zero-VCC isolation are not required. |

FAQ
What is the maximum input voltage rating for NLVLCX125DTR2G?
The NLVLCX125DTR2G supports DC input voltages from −0.5 V to +6.5 V, allowing safe interfacing with 5 V TTL logic even when powered from lower supply rails like 1.8 V or 2.5 V. This 5 V tolerance is explicitly guaranteed across the full operating temperature range and does not require external clamping circuitry.
Does NLVLCX125DTR2G support hot-plug operation?
Yes, NLVLCX125DTR2G supports live insertion and withdrawal due to its IOFF specification, which guarantees high-impedance outputs even when VCC = 0 V. This prevents back-driving powered subsystems and eliminates bus contention during hot-swap events in modular systems like PCIe add-in cards or industrial backplanes.
What is the propagation delay of NLVLCX125DTR2G at 3.3 V supply?
At VCC = 3.0–3.6 V and TA = −40 °C to +125 °C, the NLVLCX125DTR2G has a maximum propagation delay (tPLH/tPHL) of 6.0 ns. This value is measured under standard load conditions (CL = 50 pF, RL = 500 Ω) and enables reliable operation in address/data buses running up to 160 MHz.
Is NLVLCX125DTR2G qualified for automotive applications?
Yes, the NLVLCX125DTR2G is AEC-Q100 qualified (Grade 1: −40 °C to +125 °C) and PPAP capable. It undergoes rigorous stress testing including temperature cycling, high-temperature operating life, and ESD validation, making it suitable for under-hood and cabin electronics such as body control modules and infotainment interfaces.
