Product details
Overview
NLV74HC125ADTR2G from onsemi is a quad 3-state noninverting buffer IC designed for bus-oriented systems, featuring four independent active-low output enables, 2.0–6.0 V operation, ±35 mA output drive per pin, and TSSOP-14 packaging - used in memory address drivers, clock distribution, and data bus isolation.
For engineers reviewing the NLV74HC125ADTR2G datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range (2.0–6.0 V), propagation delay (15 ns @ 6.0 V), 3-state leakage (<10 µA), input compatibility with CMOS/LSTTL, and automotive-grade AEC-Q100 qualification.
Technical Context
The NLV74HC125ADTR2G implements four identical noninverting buffer channels, each with an independent active-low output enable (OE1–OE4). Its silicon-gate CMOS architecture ensures high noise immunity and low static current (≤160 µA at 6.0 V, 125°C).
Each channel supports bidirectional logic-level translation across 2.0–6.0 V, with guaranteed VOH ≥5.9 V and VOL ≤0.26 V at 6.0 V/7.8 mA. Propagation delays are tightly specified: tPLH/tPHL ≤15 ns and tPLZ/tPHZ ≤20 ns at VCC = 6.0 V and TA = 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0–6.0 V - supports wide-input rail operation including 3.3 V and 5 V systems without level shifters. |
| Output Drive | ±35 mA per pin - drives up to 15 LSTTL loads directly, eliminating need for external buffers in medium-fanout buses. |
| Propagation Delay | 15 ns max (A→Y, VCC = 6.0 V) - enables reliable timing in high-speed address/data bus applications up to ~33 MHz. |
| 3-State Leakage | ≤10 µA at 125°C - ensures minimal bus contention and signal integrity during high-impedance state in shared-bus architectures. |
| Input Thresholds | VIH = 4.2 V, VIL = 1.8 V @ VCC = 6.0 V - provides >1.2 V noise margin for robust operation in electrically noisy industrial environments. |
| Operating Temperature | –55°C to +125°C - qualified for under-hood automotive and extended industrial use cases. |
| ESD Rating | >2000 V HBM - meets IEC 61000-4-2 Level 2 requirements for board-level ESD resilience. |

TSSOP-14 package (Case 948G), 4.9 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch, Pb-free, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | Input A1–A4 | Noninverting data inputs - accept CMOS- or LSTTL-compatible logic levels; internal pull-down not provided. |
| 2, 5, 11, 14 | Output Enable OE1–OE4 | Active-low enables - assert low to enable corresponding Y output; high forces 3-state (high-Z) output. |
| 3, 6, 8, 12 | Output Y1–Y4 | Buffered noninverting outputs - drive bus lines directly; high-Z when respective OE is high. |
| 7 | GND | Ground reference for all logic and power domains - must be low-impedance connection to minimize switching noise. |
| 14 | VCC | Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin for stable high-speed operation. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 3-state noninverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74HC125ADR2G | SOIC-14 package, same electrical specs, no automotive qualification. | Lacks AEC-Q100 Grade 1 rating and PPAP support; unsuitable for production automotive designs. | Select when cost-sensitive industrial PCBs require through-hole or SOIC footprint and automotive compliance is not required. |
| SN74LVC125APWR | 3.3 V only (1.65–3.6 V), lower propagation delay (4.5 ns @ 3.3 V), higher speed but narrower voltage range. | Not compatible with 5 V systems; requires level shifting if interfacing with legacy 5 V peripherals. | Choose for high-speed 3.3 V-only designs where sub-5 ns timing is critical and mixed-voltage operation is unnecessary. |

FAQ
What is the maximum operating temperature range for NLV74HC125ADTR2G?
The NLV74HC125ADTR2G is rated for operation from –55°C to +125°C and is AEC-Q100 Grade 1 qualified. This full industrial-plus-automotive temperature range ensures reliability in engine control units, under-dash electronics, and outdoor industrial enclosures where ambient temperatures exceed standard commercial limits. The NLV74HC125ADTR2G maintains specified VOH/VOL and timing performance across this entire range.
Does NLV74HC125ADTR2G support 3.3 V logic systems?
Yes, NLV74HC125ADTR2G fully supports 3.3 V operation, with guaranteed performance across 2.0–6.0 V supply range. At VCC = 3.3 V, it delivers VOH ≥3.2 V and VOL ≤0.33 V while driving 6 mA loads, and exhibits tPLH ≤23 ns. Its CMOS inputs are compatible with both 3.3 V and 5 V logic families, enabling seamless voltage-domain bridging without external level shifters.
How does the active-low output enable work on NLV74HC125ADTR2G?
Each of the four output enables (OE1–OE4) on NLV74HC125ADTR2G is active-low: pulling an OE pin low enables its corresponding buffer output (Y1–Y4) to pass the input signal noninverted; holding OE high places that output in high-impedance (3-state) mode. This allows independent control of bus segments - for example, enabling only Y1/Y2 while tri-stating Y3/Y4 to prevent contention during multi-device communication.
Is NLV74HC125ADTR2G pin-compatible with legacy 74LS125 devices?
Yes, NLV74HC125ADTR2G is pinout-compatible with the industry-standard 74LS125 and 74LS126 logic devices in both SOIC-14 and TSSOP-14 packages. Pin assignments for inputs (A1–A4), outputs (Y1–Y4), enables (OE1–OE4), VCC, and GND match exactly - enabling drop-in replacement in existing LS-based designs while delivering superior noise immunity, lower power, and wider voltage operation.
What is the 3-state leakage current specification for NLV74HC125ADTR2G?
The NLV74HC125ADTR2G specifies maximum 3-state output leakage current (IOZ) of ±10 µA at VCC = 6.0 V and TA = 125°C. This low leakage ensures minimal bus loading and signal corruption when outputs are disabled - critical for maintaining valid logic states on shared data or address buses during idle or arbitration phases. The NLV74HC125ADTR2G meets this spec across its full temperature and voltage range.
