Product details
Overview
74LVC125APW/C5J from Nexperia is a quad 3-state buffer/line driver with 5 V tolerant inputs and outputs, operating from 1.2 V to 3.6 V supply, featuring Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and −40 °C to +125 °C temperature range - used in voltage-level translation between 3.3 V and 5 V logic domains in industrial I/O expansion and FPGA interface circuits.
For engineers reviewing the 74LVC125APW/C5J datasheet, 74LVC125APW/C5J pinout, 74LVC125APW/C5J application, or 74LVC125APW/C5J equivalent, this page delivers verified functional identity, TSSOP14 package mapping, 14-pin terminal roles, real-world timing (tpd ≤ 6.0 ns at 3.3 V), IOFF leakage < ±20 μA at VCC = 0 V, and direct substitution guidance for mixed-voltage bus driving.
Technical Context
The device implements four independent non-inverting buffers, each with active-low 3-state enable (nOE) controlling high-impedance output states. Its IOFF circuitry actively disables outputs during power-down, blocking backflow current when VCC = 0 V while inputs/outputs remain at up to 5.5 V.
Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at VCC = 3.3 V), enabling robust operation with slow-rising signals; static input thresholds are VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 3.3 V, and dynamic propagation delay is specified down to 2.5 ns (typ) and 6.0 ns (max) across −40 °C to +125 °C.
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 embedded systems without level shifters. |
| Input Voltage Tolerance | −0.5 V to +5.5 V - enables safe interfacing with 5 V TTL or CMOS sources while powered at 1.8 V or 3.3 V. |
| Propagation Delay (tpd) | ≤ 6.0 ns at VCC = 3.3 V, −40 °C to +125 °C - ensures timing-critical signal routing in high-speed digital control paths. |
| IOFF Leakage Current | ±20 μA max at VCC = 0 V, VI/VO = 5.5 V - prevents damaging back-current during hot-swap or partial power-down sequences. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets industrial-grade robustness requirements for board-level handling and field deployment. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood, motor control, and industrial automation environments. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive 50 Ω transmission lines or multiple LVC/LVT inputs without external buffering. |
Pinout & Package
TSSOP14 package (SOT402-1): plastic thin shrink small outline, 14 leads, 4.4 mm body width, 0.65 mm pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | nOE (active-low enable) | Independent 3-state control per buffer; HIGH forces output into high-impedance OFF-state. |
| 2, 5, 9, 12 | nA (data input) | Non-inverting input with Schmitt-trigger action; accepts 0–5.5 V regardless of VCC. |
| 3, 6, 8, 11 | nY (data output) | Buffered, 3-state output; drives loads up to ±24 mA with rail-to-rail swing (0 to VCC). |
| 7 | GND | Reference ground plane connection; required for stable logic thresholds and ESD path integrity. |
| 14 | VCC | Primary supply input; powers internal logic and output drivers; must be decoupled locally. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V tolerant I/O | Inputs and outputs withstand up to 5.5 V independently of VCC, enabling seamless 3.3 V ↔ 5 V bidirectional translation. |
| IOFF partial power-down | Outputs automatically enter high-Z and block reverse current when VCC = 0 V, supporting hot-plug and power-gating architectures. |
| Schmitt-trigger inputs | Hysteresis ≥ 0.3 V at 3.3 V supply rejects noise on slow edges, eliminating need for external RC filtering in noisy environments. |
| JEDEC-compliant voltage ranges | Fully compliant with JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V) standards. |
| Industrial temperature grade | Specified over −40 °C to +125 °C ambient, with derated power dissipation above 81 °C for TSSOP14 package. |
Applications

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, same 1.2–3.6 V range and 5 V tolerance; slightly higher ICC (max 40 μA vs 10 μA) and wider tpd range (1.5–7.5 ns). | Validated for TI-specific reference designs; pinout identical but thermal resistance differs (TSSOP14 RθJA = 137 K/W vs Nexperia's 136 K/W). | Select if sourcing from TI-authorized channels or requiring TI's extended qualification reports (e.g., AEC-Q100 stress data). |
| 74ALVC125PW (Nexperia) | Higher speed (tpd ≤ 3.5 ns typ), lower input capacitance (2.5 pF), but narrower VCC range (1.65–3.6 V) and no 1.2 V operation. | Better suited for high-frequency clock distribution; lacks 1.2 V support needed for ultra-low-power IoT nodes. | Choose when timing budget is tighter than 4 ns and system operates ≥1.65 V; avoid if 1.2 V brown-out operation is required. |
Compared with SN74LVC125APWR, 74LVC125APW/C5J offers lower quiescent current and marginally better thermal performance; versus 74ALVC125PW, it trades speed for broader voltage flexibility and lower cost in battery-sensitive applications.

FAQ
Can 74LVC125APW/C5J operate at 1.2 V supply while accepting 5 V inputs?
Yes. The device is fully specified from 1.2 V to 3.6 V supply and guarantees 5 V tolerant inputs (up to 5.5 V) across the entire range. At 1.2 V VCC, VIH is 1.08 V min and VIL is 0.12 V max, with input clamping current limited to ±50 mA - enabling safe 5 V signal reception without external resistors or diodes.
Does the TSSOP14 package include an exposed thermal pad?
No. The SOT402-1 (TSSOP14) package used for 74LVC125APW/C5J has no exposed pad; thermal dissipation relies solely on lead-frame conduction through pins 7 (GND) and 14 (VCC). Maximum power dissipation is 500 mW at Tamb ≤ 81 °C, derating linearly at 7.3 mW/K above that temperature.
How does IOFF protect the device during partial power-down?
When VCC = 0 V, the IOFF circuit disables all output drivers and presents high-impedance terminals, limiting backflow current to ±20 μA maximum even if inputs or outputs are held at 5.5 V - preventing latch-up, overheating, or damage to upstream/downstream devices in hot-swap or multi-rail power sequencing scenarios.
Is the Schmitt-trigger input hysteresis specified in the datasheet?
While absolute hysteresis values are not tabulated, the datasheet confirms Schmitt-trigger action at all inputs and specifies VIH/VIL thresholds with guaranteed margins: at VCC = 3.3 V, VIH min = 2.0 V and VIL max = 0.8 V, yielding ≥1.2 V total hysteresis - sufficient to reject noise spikes up to ±600 mV on slow edges (Δt/ΔV ≤ 10 ns/V).
