Product details
Overview
74LV125PW,118 from NXP Semiconductors is a low-voltage CMOS quad non-inverting buffer/line driver with 3-state outputs, operating from 1.0 V to 5.5 V supply, featuring 14-pin TSSOP package, −40 °C to +125 °C temperature range, and pin/function compatibility with 74HC125/74HCT125 for bus interface and signal isolation in digital systems.
For engineers reviewing the 74LV125PW,118 datasheet, 74LV125PW,118 pinout, 74LV125PW,118 application, or 74LV125PW,118 equivalent, key selection criteria include supply voltage flexibility (1.0–5.5 V), guaranteed 3-state timing (enable/disable times ≤23 ns at 3.3 V), output drive capability (±16 mA), ESD robustness (HBM >2000 V), and industrial-temperature operation without derating below 60 °C.
Technical Context
The 74LV125PW,118 implements four independent non-inverting buffers, each with active-low 3-state enable (nOE) controlling high-impedance output (Z) when asserted. Its Si-gate CMOS process enables TTL-level input compatibility at VCC = 2.7–3.6 V and supports mixed-voltage interfacing across 1.2 V to 5.5 V logic domains.
Dynamic performance is characterized by propagation delay (tpd) as low as 9 ns at VCC = 3.3 V and CL = 15 pF, enable time (ten) ≤18 ns, and disable time (tdis) ≤24 ns over full temperature range - all specified with defined measurement points (VM = 1.5 V for 2.7–3.6 V VCC) and load conditions (CL = 15/50 pF).
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 families without level shifters. |
| Operating Temperature | −40 °C to +125 °C - qualified for automotive under-hood, industrial control, and extended-environment applications. |
| Propagation Delay (tpd) | 9 ns typical at VCC = 3.3 V, CL = 15 pF - ensures sub-10 ns signal path timing for high-speed bus buffering. |
| Output Drive Strength | ±16 mA at VCC = 4.5 V - supports driving 15 pF loads with <0.55 V VOL and >3.5 V VOH under full load. |
| ESD Protection | HBM >2000 V, MM >200 V - provides robust handling during PCB assembly and system integration. |
| Input Compatibility | TTL-level inputs accepted at VCC = 2.7–3.6 V - allows seamless connection to legacy 5 V TTL outputs without external resistors. |
| Power Dissipation Cap | 500 mW max at Tamb ≤60 °C (TSSOP14) - defines thermal design margin before linear derating (5.5 mW/K above 60 °C). |
Pinout & Package
74LV125PW,118 is housed in a 14-lead plastic thin shrink small outline package (TSSOP14), body width 4.4 mm, pitch 0.65 mm, compliant with JEDEC MO-153 and JEITA EIAJ ED-7401A standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | Output Enable (nOE) | Active-low control per buffer; HIGH forces output into high-impedance state, enabling bus sharing. |
| 2, 5, 9, 12 | Data Input (nA) | Non-inverting input for each buffer; accepts CMOS- or TTL-compatible logic levels depending on VCC. |
| 3, 6, 8, 11 | Data Output (nY) | Buffered non-inverting output; drives loads up to ±16 mA while maintaining rail-to-rail VOH/VOL. |
| 7 | GND | Ground reference (0 V); must be low-impedance connection to minimize ground bounce (<0.8 V typical at 3.3 V). |
| 14 | VCC | Positive supply; decoupling capacitor (100 nF) recommended near pin to suppress switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 1.0 V to 5.5 V operation - eliminates need for separate voltage rails in mixed-supply systems. |
| 3-State Timing Control | Enable/disable times ≤23 ns at 3.3 V - minimizes bus contention windows in multi-driver configurations. |
| Low Ground Bounce | Typical <0.8 V at VCC = 3.3 V - reduces noise coupling into adjacent signals and improves signal integrity. |
| High-Speed Propagation | 9 ns typical tpd at 3.3 V/15 pF - supports >50 MHz data rates in buffered address/data paths. |
| Industrial Temp Grade | −40 °C to +125 °C specification - validated for continuous operation in harsh thermal environments. |

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 1.8 V, but identical pinout and 3-state behavior. | Better suited for ultra-low-power battery-operated devices where static current dominates budget. | Select 74LVC125PW,118 when VCC ≤2.5 V and quiescent current <10 µA is critical; retain 74LV125PW,118 for wider 1.0–5.5 V tolerance and proven 5 V TTL compatibility. |
| SN74LV125APWR | TI variant with same logic function, 14-pin TSSOP, −40 °C to +125 °C rating, but different AC specs (tpd = 7.5 ns typ at 3.3 V) and slightly higher VOL (0.55 V max). | Offers faster propagation in TI-optimized designs but requires validation of output voltage margins in noise-sensitive systems. | Choose SN74LV125APWR only if layout reuse with TI reference designs is prioritized; otherwise, 74LV125PW,118 provides broader voltage margin and NXP's documented HBM >2000 V ESD robustness. |
Compared with 74LVC125PW,118 and SN74LV125APWR, the 74LV125PW,118 uniquely balances wide supply range (1.0–5.5 V), industrial temperature reliability, and TTL-input compatibility - making it the preferred choice for legacy interface bridging and mixed-voltage bus isolation where absolute minimum ICC is not the primary constraint.

FAQ
What is the maximum supply voltage rating for the 74LV125PW,118?
The 74LV125PW,118 has an absolute maximum supply voltage (VCC) of +7.0 V, but its recommended operating range is 1.0 V to 5.5 V. Operation beyond 5.5 V risks violating static characteristics and may cause permanent damage, even if within limiting values for short durations.
Does the 74LV125PW,118 support TTL-level inputs at all supply voltages?
No - the 74LV125PW,118 accepts TTL input levels only when VCC is between 2.7 V and 3.6 V, as specified in Table 6. At VCC = 1.2 V or 5.0 V, inputs must meet CMOS thresholds (VIH ≥ 0.7VCC, VIL ≤ 0.3VCC); TTL compatibility is not guaranteed outside the 2.7–3.6 V window.
What is the thermal derating behavior of the 74LV125PW,118 in its TSSOP14 package?
The 74LV125PW,118 in TSSOP14 has a total power dissipation limit of 500 mW up to +60 °C ambient. Above that, Ptot derates linearly at 5.5 mW/K - meaning at +80 °C, maximum allowable power drops to 390 mW (500 − 5.5 × 20), requiring careful thermal design in enclosed enclosures.
Can the 74LV125PW,118 be used as a direct replacement for 74HC125 in existing designs?
Yes - the 74LV125PW,118 is explicitly stated as pin and function compatible with 74HC125 and 74HCT125. However, verify VCC compatibility: 74LV125PW,118 operates down to 1.0 V and up to 5.5 V, whereas 74HC125 requires ≥2.0 V, so low-voltage operation may require circuit review.
What is the typical ground bounce voltage measured on the 74LV125PW,118?
The 74LV125PW,118 exhibits typical output ground bounce of <0.8 V at VCC = 3.3 V and Tamb = 25 °C, as measured under standard switching conditions. This value reflects transient voltage drop on the GND pin during simultaneous output transitions and informs PCB decoupling and grounding strategy.
