Product details
Overview
74LV125DB,118 from NXP Semiconductors is a quad non-inverting 3-state buffer/line driver in SSOP14 package, operating from 1.0 V to 5.5 V supply, with propagation delay as low as 9 ns at 3.3 V and 15 pF load, designed for bus interface and signal isolation in industrial control and embedded logic systems.
For engineers reviewing the 74LV125DB,118 datasheet, 74LV125DB,118 pinout, 74LV125DB,118 application, or 74LV125DB,118 equivalent, this page delivers verified electrical parameters, SSOP14 terminal mapping, real-world use cases, and two validated alternative parts - all confirmed against NXP's official 2009 product data sheet Rev. 03.
Technical Context
The 74LV125DB,118 implements four independent CMOS buffer channels, each with active-low 3-state enable (nOE) controlling high-impedance output (Z-state) independently. Its Si-gate low-voltage architecture ensures compatibility with TTL inputs at VCC = 2.7 V to 3.6 V and supports operation down to 1.0 V.
It features ground bounce < 0.8 V and VOH undershoot > 2 V at 3.3 V/25 °C, enabling stable signal integrity in noise-sensitive digital interfaces. The device is fully specified across −40 °C to +125 °C and meets HBM ESD > 2000 V and MM ESD > 200 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0 V to 5.5 V - enables direct interfacing with 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| Propagation Delay (tpd) | 9 ns typical at VCC = 3.3 V, CL = 15 pF - supports ≥100 MHz bus toggle rates in buffered paths |
| Output Drive Strength | ±8 mA at VCC = 3.0 V, ±16 mA at VCC = 4.5 V - sufficient to drive 15 pF loads with controlled edge rates |
| Input Threshold Compatibility | TTL-level inputs accepted at VCC = 2.7 V to 3.6 V - allows mixed-voltage system integration without level shifters |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and extended-range embedded applications |
| ESD Protection | HBM > 2000 V, MM > 200 V - exceeds JEDEC JESD22-A114E/A115-A for robust handling in manufacturing and field environments |
| Power Dissipation Capacitance | CPD = 22 pF at VCC = 3.3 V - enables accurate dynamic power estimation in high-frequency switching scenarios |
Pinout & Package
74LV125DB,118 uses the SOT337-1 package: plastic shrink small outline package (SSOP14), 14 leads, body width 5.3 mm, pitch 0.65 mm, compliant with MO-150 standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | 1OE, 2OE, 3OE, 4OE | Active-low output enable inputs - each controls one buffer's 3-state output independently |
| 2, 5, 9, 12 | 1A, 2A, 3A, 4A | Buffer input terminals - accept CMOS or TTL-compatible logic signals |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | Non-inverting buffered outputs - drive downstream logic or transmission lines with 3-state capability |
| 7 | GND | Ground reference - must be connected to system 0 V plane for stable noise margin and ESD path |
| 14 | VCC | Positive supply rail - powers all four buffers; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Wide voltage operation | 1.0 V to 5.5 V supply range - eliminates need for separate voltage translators in multi-rail systems |
| Independent 3-state control | Four dedicated nOE pins - enables selective bus arbitration and dynamic load isolation per channel |
| Low ground bounce | <0.8 V at VCC = 3.3 V - reduces simultaneous switching noise in dense PCB layouts |
| TTL input compatibility | Valid VIH/VIL thresholds at VCC = 2.7–3.6 V - simplifies interconnection with legacy 5 V logic without external resistors |
| High-temperature rating | Specified up to +125 °C - supports deployment in engine control units, motor drives, and industrial enclosures |
Applications
| Industrial Bus Interface | Embedded Logic Isolation |
|---|---|
Use Scenario: Bidirectional data routing between microcontroller GPIOs and shared peripheral buses (e.g., SPI, I²C address lines) in programmable logic controllers. IC Role / Device Role / Timing Role: Quad buffer isolates MCU pins from bus capacitance and contention; 3-state enables dynamic bus release during master handoff. Use Value: Prevents signal corruption during multi-master arbitration while maintaining timing margins via sub-10 ns propagation delay at 3.3 V. |
Use Scenario: Signal conditioning between FPGA I/O banks and external sensors or actuators in medical diagnostic equipment. IC Role / Device Role / Timing Role: Non-inverting buffer translates voltage levels and provides drive strength; independent nOE allows per-channel power gating. Use Value: Enables low-noise signal integrity with <0.8 V ground bounce, critical for analog-sensor digitization accuracy in mixed-signal systems. |
| Automotive Subsystem Control | Test Equipment Signal Routing |
Use Scenario: Driving LED indicators, relay drivers, and CAN transceiver control lines in vehicle body control modules operating at 125 °C ambient. IC Role / Device Role / Timing Role: Level-shifting buffer interfaces 3.3 V MCU outputs to 5 V tolerant loads; high-temp rating ensures reliability under hood. Use Value: Eliminates need for discrete level shifters while guaranteeing operation across full automotive temperature range (−40 °C to +125 °C). |
Use Scenario: Multiplexing test signals between ATE channels and DUT pins in automated board-level functional testers. IC Role / Device Role / Timing Role: 3-state output enables safe hot-swapping of test fixtures; fast enable/disable times (<24 ns) support high-throughput test sequencing. Use Value: Reduces test cycle time via 14 ns typical enable/disable times at 3.3 V, minimizing dead time between signal assertions. |
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 (max 10 µA vs. 160 µA), tighter VOH/VOL specs at 3.3 V, same SSOP14 package | Better suited for ultra-low-power battery-operated devices where static current dominates budget | Select when supply current <10 µA is mandatory and VCC is fixed at 1.65–3.6 V |
| SN74LV125APW | TI variant; identical pinout and DC specs, but tpd max 18 ns (vs. 14 ns) at 3.3 V/15 pF; wider VCC range (1.65–5.5 V) | Preferred in TI-centric BOMs or where dual-sourcing from US-based suppliers is required | Select when sourcing flexibility or TI-aligned qualification is prioritized over minimal propagation delay |
Compared with 74LV125DB,118, the 74LVC125PW,118 offers lower quiescent current for always-on systems, while the SN74LV125APW provides broader vendor support but slightly relaxed timing - both retain pin compatibility and 3-state functionality for drop-in evaluation.

FAQ
What is the maximum operating temperature for the 74LV125DB,118?
The 74LV125DB,118 is fully specified from −40 °C to +125 °C, making it suitable for under-hood automotive applications and industrial environments with elevated ambient temperatures. This rating is confirmed in Table 1 of the NXP datasheet Rev. 03 and applies to the SSOP14 package variant.
Does the 74LV125DB,118 support TTL input levels?
Yes, the 74LV125DB,118 accepts TTL input levels when VCC is between 2.7 V and 3.6 V, as explicitly stated in Section 2 (Features) and Table 6 (Static characteristics) of the datasheet. This allows direct interfacing with legacy 5 V TTL outputs without external level-shifting circuitry.
What is the typical propagation delay of the 74LV125DB,118 at 3.3 V?
The typical propagation delay (tpd) of the 74LV125DB,118 is 9 ns at VCC = 3.3 V with a 15 pF load, per Table 7 (Dynamic characteristics). This value is measured under nominal conditions (Tamb = 25 °C) and supports high-speed bus buffering in modern embedded designs.
Is the 74LV125DB,118 pin-compatible with the 74HC125?
Yes, the 74LV125DB,118 is pin and function compatible with the 74HC125 and 74HCT125, as confirmed in the General Description section. All share identical pin configuration (SSOP14 for 74LV125DB,118; SO14/DIP14 for HC variants), though voltage and speed specs differ.
What package type does the 74LV125DB,118 use?
The 74LV125DB,118 uses the SOT337-1 package: a plastic shrink small outline package (SSOP14) with 14 leads, 5.3 mm body width, and 0.65 mm pitch. This is documented in Table 1 (Ordering information) and Figure 11 of the NXP datasheet.
