Product details
Overview
74LV125PW,112 from NXP Semiconductors is a low-voltage Si-gate CMOS quad non-inverting buffer/line driver with 3-state outputs, pin- and function-compatible with 74HC125 and 74HCT125. It operates from 1.0 V to 5.5 V, supports TTL input levels at VCC = 2.7 V–3.6 V, delivers ≤14 ns propagation delay at 3.3 V, and is rated for −40 °C to +125 °C ambient operation - used in bus interface and level-shifting circuits in industrial control and embedded logic systems.
For engineers reviewing the 74LV125PW,112 datasheet, 74LV125PW,112 pinout, 74LV125PW,112 application, or 74LV125PW,112 equivalent, key selection criteria include 3-state output timing (enable/disable times ≤23 ns), wide supply range (1.0–5.5 V), guaranteed operation down to 1.0 V, ESD robustness (>2000 V HBM), and TSSOP14 package compatibility with high-density PCB layouts.
Technical Context
The 74LV125PW,112 implements four independent non-inverting buffers, each with an active-low 3-state output enable (nOE) controlling high-impedance OFF-state behavior. Its CMOS architecture ensures rail-to-rail output swing and low static current (≤20 µA at 5.5 V), while TTL-compatible inputs simplify interfacing with legacy logic families across 2.7–3.6 V supply conditions.
Dynamic performance is characterized by propagation delay (tpd), enable time (ten), and disable time (tdis), all specified over temperature and voltage - e.g., tpd = 9 ns (typ) at VCC = 3.3 V, CL = 15 pF; ten/tdis = 14–23 ns (max) across −40 °C to +125 °C. Input transition rate limits are voltage-dependent, tightening from 500 ns/V at 1.0–2.0 V to 50 ns/V above 3.6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0 V to 5.5 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| Propagation Delay (tpd) | 9 ns (typ) at VCC = 3.3 V, CL = 15 pF - supports >50 MHz bus toggle rates in high-speed digital interfaces. |
| Enable/Disable Time | 14–23 ns (max) at VCC = 3.0–3.6 V, −40 °C to +125 °C - ensures precise bus arbitration timing in shared-data-path applications. |
| Input Voltage Compatibility | TTL-level inputs accepted at VCC = 2.7–3.6 V - allows seamless integration with 5 V-tolerant microcontrollers and legacy peripherals. |
| ESD Protection | HBM >2000 V, MM >200 V - provides robust handling margin during board assembly and field service without external protection. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive, industrial motor drives, and outdoor telecom equipment. |
| Output Drive Strength | ±8 mA at VCC = 3.0 V (VOH/VOL), ±16 mA at VCC = 4.5 V - sufficient to drive 15 pF loads with <0.4 V ground bounce at 3.3 V. |
Pinout & Package
74LV125PW,112 uses the SOT402-1 (TSSOP14) package: plastic thin shrink small outline, 14 leads, 4.4 mm body width, 0.65 mm lead pitch, and exposed pad not present. Pin 1 is marked by a dot or beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 (1OE–4OE) | Active-low output enable | Drives corresponding Y output into high-impedance state when HIGH; enables concurrent bus sharing across four channels. |
| 2, 5, 9, 12 (1A–4A) | Data input | Non-inverting logic input per buffer; accepts TTL thresholds at VCC ≥2.7 V and full CMOS swing otherwise. |
| 3, 6, 8, 11 (1Y–4Y) | 3-state buffered output | Drives HIGH/LOW or floats (Z) based on nOE; supports wired-OR and multiplexed bus topologies. |
| 7 (GND) | Ground reference | Primary return path for all I/O and supply currents; must be low-inductance connection to minimize ground bounce. |
| 14 (VCC) | Positive supply | Single supply rail powering all four buffers; decoupling capacitor (100 nF) required within 1 cm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 1.0 V to 5.5 V operation - eliminates need for separate voltage regulators in mixed-supply systems. |
| Guaranteed 1.0 V functionality | Functional down to VCC = 1.0 V with GND/VCC input levels - supports ultra-low-power wake-up and battery-backed logic. |
| Low ground bounce | Typical <0.8 V at VCC = 3.3 V, Tamb = 25 °C - reduces noise coupling into adjacent analog or RF sections. |
| High-temperature rating | Specified from −40 °C to +125 °C - validated for extended life in thermally stressed environments without derating. |
| Multiple package options | TSSOP14 (SOT402-1) footprint - enables high-density routing and automated assembly compatible with SO14 land patterns. |
Applications
| Industrial Bus Interface | Microcontroller GPIO Expansion |
|---|---|

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 |
|---|---|---|---|
| 74LVC125PW,118 | Lower ICC (10 µA max), tighter VOH/VOL specs at 1.8 V, but only rated to +85 °C. | Suitable for portable consumer electronics where power and 1.8 V compatibility are critical, but not for extended-temperature industrial use. | Select 74LVC125PW,118 only if ambient stays ≤85 °C and 1.8 V operation is required; otherwise retain 74LV125PW,112 for full −40 °C to +125 °C coverage. |
| SN74LV125APW | Identical electrical specs and pinout; TI's version uses same SOT402-1 package and shares NXP's 74LV125 functional spec. | No functional difference; dual-sourcing option for supply chain resilience in high-volume production. | SN74LV125APW is a second-source alternative with identical timing, voltage, and thermal specs - ideal for BOM diversification without redesign. |
Compared with 74LVC125PW,118, the 74LV125PW,112 offers broader temperature support and higher drive strength at 3.3 V; versus SN74LV125APW, it provides identical performance with NXP-specific qualification and traceability - making it preferred for automotive-qualified or long-lifecycle industrial programs.

FAQ
What is the maximum operating frequency supported by the 74LV125PW,112?
The 74LV125PW,112 does not specify a maximum clock frequency, but its propagation delay (tpd = 9 ns typ at 3.3 V, CL = 15 pF) supports reliable data toggling up to approximately 55 MHz in bus applications. Actual usable frequency depends on load capacitance, trace impedance, and system timing margins - design validation is required for >30 MHz operation.
Is the 74LV125PW,112 pin-compatible with the 74HC125 and 74HCT125?
Yes, the 74LV125PW,112 is explicitly pin- and function-compatible with both 74HC125 and 74HCT125, sharing identical pinout (TSSOP14), logic diagram, and truth table. However, its wider 1.0–5.5 V supply range and lower dynamic power distinguish it from those families - no PCB changes are needed for drop-in replacement in existing designs.
Does the 74LV125PW,112 require external pull-up or pull-down resistors on its 3-state outputs?
No, the 74LV125PW,112 does not require external pull-up or pull-down resistors on its 3-state outputs (1Y–4Y) when used in properly terminated bus systems. Its high-impedance OFF-state leakage (IOZ ≤10 µA at VCC = 5.5 V) is sufficiently low to prevent floating nodes in typical PCB environments - external resistors are only needed if bus leakage or EMI susceptibility exceeds system requirements.
Can the 74LV125PW,112 operate reliably at 1.2 V supply voltage?
Yes, the 74LV125PW,112 is fully specified and guaranteed to operate at VCC = 1.2 V, with static characteristics including VIH/VIL thresholds and VOH/VOL levels validated across −40 °C to +125 °C. At 1.2 V, propagation delay increases to 55 ns (typ), and output drive is reduced - but logic functionality remains intact for ultra-low-power monitoring and wake-up circuits.
What is the thermal resistance (RθJA) of the 74LV125PW,112 in its TSSOP14 package?
The 74LV125PW,112 in SOT402-1 (TSSOP14) has a junction-to-ambient thermal resistance (RθJA) of 182 K/W, derived from its 500 mW total power dissipation limit and 60 °C derating threshold. This value assumes standard JEDEC 2-layer board conditions (1 inch² copper); actual RθJA improves with additional copper area or thermal vias beneath the package.
