Product details
Overview
74LVC125APW,112 from Nexperia is a quad 3-state buffer/line driver with 5 V tolerant inputs and outputs, operating across 1.2 V–3.6 V supply, supporting mixed-voltage translation between 3.3 V and 5 V systems, featuring Schmitt-trigger inputs for noise immunity and IOFF circuitry for partial power-down protection. It is used in bus interface and level-shifting applications in industrial control and embedded communication subsystems.
For engineers reviewing the 74LVC125APW,112 datasheet, 74LVC125APW,112 pinout, 74LVC125APW,112 application, or 74LVC125APW,112 equivalent, this device is selected for its 5 V tolerance on all I/O pins, guaranteed 3-state isolation under power-down, sub-6 ns propagation delay at 3.3 V, and TSSOP14 packaging suitable for high-density PCB layouts.
Technical Context
The 74LVC125APW implements four independent non-inverting buffers, each with an active-low output enable (nOE) controlling high-impedance state. Its CMOS design ensures rail-to-rail input thresholds compliant with JEDEC JESD8-7A, JESD8-5A, and JESD8-C standards across 1.65 V–3.6 V operation.
Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at 3.3 V), enabling robust operation with slow-rising signals. The IOFF feature disables outputs when VCC = 0 V, limiting backflow current to ±10 μA at 5.5 V, making it suitable for hot-swap and multi-rail power sequencing environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.2 V to 3.6 V - supports single-supply operation in low-voltage microcontroller I/O domains and battery-powered logic interfaces. |
| Input/output voltage tolerance | Up to 5.5 V - enables direct connection to 5 V peripherals without external level shifters in mixed-voltage buses. |
| Propagation delay (tpd) | 1.0 ns to 6.0 ns (VCC = 1.2 V to 3.6 V) - ensures timing-critical signal buffering with sub-6 ns latency at full 3.3 V operation. |
| IOFF leakage current | ±10 μA max at VCC = 0 V, VI/VO = 5.5 V - prevents damaging back-current during partial power-down or system reset sequences. |
| Operating temperature | −40 °C to +125 °C - qualified for extended industrial and automotive under-hood ambient conditions. |
| ESD protection | HBM >2000 V, CDM >1000 V - meets robustness requirements for handling and board-level integration without additional protection circuitry. |
| Output drive strength | ±24 mA at VCC = 3.0 V - sufficient to drive 50 pF loads with <6 ns rise/fall times, compatible with standard TTL and LVC fanout requirements. |
Pinout & Package
TSSOP14 package (SOT402-1): plastic thin shrink small outline, 14-lead, 4.4 mm body width, 0.65 mm pitch, 1.2 mm max height - optimized for automated assembly and thermal performance in space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | nOE (active-low output enable) | Independent per-buffer control: HIGH forces output into high-impedance state; LOW enables non-inverting pass-through of input to output. |
| 2, 5, 9, 12 | nA (data input) | CMOS input with Schmitt-trigger hysteresis - accepts slow edges and rejects noise; tolerant to 5.5 V regardless of VCC. |
| 3, 6, 8, 11 | nY (data output) | 3-state CMOS output with 5.5 V tolerance; drives up to ±24 mA; IOFF active when VCC = 0 V. |
| 7 | GND | Reference ground plane connection - must be low-inductance for stable switching and EMI control. |
| 14 | VCC | Primary supply rail - decoupling capacitor (100 nF ceramic) required within 5 mm for noise suppression and transient current delivery. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V tolerant I/O | Inputs and outputs withstand up to 5.5 V independently of VCC - eliminates need for discrete level translators in 3.3 V ↔ 5 V interconnects. |
| IOFF partial power-down | Outputs disabled and leakage limited to ±10 μA when VCC = 0 V - enables safe insertion/removal in live backplanes and multi-supply systems. |
| Schmitt-trigger inputs | Hysteresis ≥0.3 V at 3.3 V - suppresses chatter on noisy or slow-rising control lines (e.g., pushbutton debouncing, long trace interfaces). |
| JEDEC-compliant voltage ranges | Fully specified for JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V) - ensures interoperability across legacy and modern low-voltage logic families. |
| Wide temperature range | −40 °C to +125 °C operation - validated for use in industrial motor drives, PLC I/O modules, and automotive body electronics without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC125APWR (TI) | Identical logic function, 1.65 V–3.6 V VCC range, same TSSOP14 package, but rated only to +85 °C (not +125 °C); IOFF not explicitly characterized in datasheet. | Limited to commercial/industrial ambient environments below 85 °C; unsuitable for under-hood or high-temp industrial enclosures. | Select when cost sensitivity outweighs extended temperature requirement and IOFF assurance is not critical. |
| 74LVC125AD,118 (Nexperia SO14) | Same electrical specs and temperature rating, but SO14 package (SOT108-1) - larger footprint (8.75 mm × 3.9 mm vs. 5.1 mm × 4.4 mm), lower thermal resistance (10.1 mW/K derating above 100 °C vs. 7.3 mW/K). | Better thermal performance in high-power-density applications; less suitable for fine-pitch automated assembly due to wider lead pitch (1.27 mm vs. 0.65 mm). | Select when board-level thermal management is prioritized over space constraints and reflow compatibility with 0.5 mm pitch processes. |
Compared with SN74LVC125APWR and 74LVC125AD,118, the 74LVC125APW,112 uniquely combines +125 °C qualification, verified IOFF behavior, and TSSOP14 miniaturization - making it optimal for thermally demanding, space-constrained, and hot-swap-capable industrial designs.

FAQ
Can 74LVC125APW,112 operate with a 1.2 V supply and still accept 5 V inputs?
Yes. The device is fully specified from 1.2 V to 3.6 V supply and guarantees 5.5 V input tolerance across that entire range. Input clamping diodes and internal protection circuitry allow safe operation even when driven by 5 V sources while VCC is at minimum 1.2 V - confirmed in Table 4 (Limiting Values) and Table 5 (Recommended Operating Conditions).
What is the maximum capacitive load the outputs can drive while maintaining specified timing?
The 74LVC125APW,112 is characterized up to 50 pF load capacitance (see Table 9 test conditions). At VCC = 3.0 V–3.6 V, it delivers <6.0 ns propagation delay and <7.0 ns disable time into 50 pF with 500 Ω termination. Driving >50 pF increases delay nonlinearly and may exceed timing budgets - external series resistors or buffer staging are recommended beyond this limit.
Does the IOFF feature require any external bias or configuration?
No. IOFF is fully automatic and requires no external components or configuration. When VCC = 0 V, the internal circuitry disables all outputs and limits leakage current to ±10 μA (max) regardless of input or output voltage (up to 5.5 V), as verified in Table 6 (Static Characteristics) under IOFF parameter.
Is the TSSOP14 package (SOT402-1) RoHS and REACH compliant?
Yes. Nexperia confirms SOT402-1 packaging for 74LVC125APW,112 meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, including SVHC screening. Full compliance documentation, including substance declarations and test reports, is available via Nexperia's product change notification portal and Aetrix Electronics' material compliance library.
