Product details

Overview

74LVC1G125 from Nexperia is a single 3-state bus buffer/line driver with Schmitt-trigger inputs, IOFF partial power-down protection, and 1.65 V to 5.5 V supply operation. It enables level translation between 3.3 V and 5 V logic domains, supports ±24 mA output drive at 3.0 V, and operates across –40 °C to +125 °C for industrial interface isolation in microcontroller I/O expansion.

For engineers reviewing the 74LVC1G125 datasheet, 74LVC1G125 pinout, 74LVC1G125 application, or 74LVC1G125 equivalent, this device is selected for low-voltage mixed-supply signal buffering where input tolerance, high noise immunity, and power-down safety are critical - especially in space-constrained embedded control and sensor interface designs.

Technical Context

The 74LVC1G125 implements a non-inverting buffer with active-low 3-state enable (OE), supporting bidirectional voltage translation via overvoltage-tolerant inputs rated to 5.5 V regardless of VCC. Its Schmitt-trigger inputs accept slow-rising signals down to 10 ns/V transition rate, eliminating external hysteresis components.

IOFF circuitry actively disables the output when VCC = 0 V, blocking backflow current and enabling hot-swap capability in powered-backplane systems. The device complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36 across its full 1.65–5.5 V operating range.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.65 V to 5.5 V - Enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters.
Input Voltage Tolerance	Up to 5.5 V - Allows 5 V inputs to be safely driven into 3.3 V or lower VCC systems without clamping diodes or external protection.
Output Drive Strength	±24 mA at VCC = 3.0 V - Sufficient to drive 50 Ω transmission lines or multiple CMOS/TTL loads in point-to-point or stubbed bus topologies.
Propagation Delay	0.5–4.5 ns (VCC = 3.0–3.6 V) - Supports >100 MHz data rates in short-reach digital interconnects with deterministic timing.
IOFF Leakage Current	±2 μA at VCC = 0 V - Prevents damaging backfeed current during partial system power-down, meeting IEC 61000-4-2 ESD robustness requirements.
Operating Temperature	–40 °C to +125 °C - Qualified for under-hood automotive, industrial PLC, and outdoor IoT edge node environments.
ESD Protection	HBM >2000 V, CDM >1000 V - Reduces need for external TVS devices in board-level ESD protection schemes.

Pinout & Package

XSON5 plastic thermal-enhanced extremely thin small outline package with side-wettable flanks (SWF); 5 terminals; body size 1.1 × 0.85 × 0.5 mm (SOT8065-1). Exposed die pad improves thermal performance in high-density PCB layouts.

Pin/Terminal	Circuit Role	Design Meaning
GND	Ground reference	Primary return path for all internal logic and output current; must be low-impedance connection to minimize ground bounce.
VCC	Power supply	Supplies core logic and output stage; decoupling capacitor (100 nF) required within 2 mm of this pin for stable switching.
Y	Buffered output	Non-inverting, 3-state output; enters high-impedance state when OE is HIGH, enabling bus sharing without contention.
OE	Active-low enable	Low-level assertion enables Y; tied HIGH or controlled by MCU GPIO to manage bus arbitration or power sequencing.
A	Data input	Schmitt-trigger input accepts slow or noisy signals; threshold hysteresis prevents chatter on marginal edges.

Key Features

Feature	Design Value
Wide supply range	Operates from 1.65 V to 5.5 V - eliminates need for separate voltage translators in multi-rail systems.
IOFF partial power-down	Blocks backflow current when VCC = 0 V - enables safe insertion/removal in live backplanes and modular subsystems.
Schmitt-trigger inputs	Input hysteresis ≥0.3 V at 3.3 V - rejects noise on long traces or unshielded cables without external RC filtering.
Overvoltage-tolerant inputs	Withstands 5.5 V input regardless of VCC - simplifies design of mixed-voltage interfaces such as USB-C PD controller signaling.
Thermal-enhanced XSON5	R_θJA ≈ 220 °C/W (typ.) - supports continuous operation at 125 °C ambient in compact 1.1 mm × 0.85 mm footprint.

Equivalent & Alternatives

The following parts are listed as comparable options for similar bus buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G125DBVR	TI part in SOT-23-5 package; identical logic function but lacks side-wettable flanks and has higher R_θJA (300 °C/W).	Less suitable for automated optical inspection (AOI) and reflow profiling in high-volume manufacturing due to non-SWF package.	Select when legacy SOT-23 footprint compatibility is required and thermal margin exceeds 20 °C.
74AUP1G125GW	Nexperia AUP variant; lower static current (0.9 μA vs. 4 μA), wider VCC range (0.8–3.6 V), but no 5 V tolerance.	Not usable in mixed 3.3 V/5 V systems; limited to ultra-low-power sub-2 V domains like wearables or energy harvesting nodes.	Select only for battery-powered applications requiring sub-1 μA ICC and where 5 V inputs are absent.

Compared with SN74LVC1G125DBVR and 74AUP1G125GW, the 74LVC1G125GZ offers superior manufacturability via SWF leads, guaranteed 5 V input tolerance across full VCC range, and tighter thermal resistance - making it optimal for automotive and industrial designs demanding reliability, testability, and mixed-voltage interoperability.

FAQ

Can the 74LVC1G125GZ drive a 50 Ω transmission line directly?

Yes - at VCC = 3.0 V, it delivers ±24 mA output drive, sufficient to source/sink full swing into a 50 Ω load (requiring ≤60 mA for 3 Vpp). Propagation delay remains under 4.5 ns, preserving signal integrity up to ~100 MHz. Layout must include controlled impedance routing and local VCC decoupling.

Does the IOFF feature work when VCC is disconnected but OE and A remain biased?

Yes - IOFF activates when VCC = 0 V, regardless of OE or A voltage. Input and output are isolated; leakage stays below ±2 μA even if 5.5 V is applied to A or Y. This meets IEC 61000-4-2 system-level ESD survivability requirements during maintenance or hot-swap events.

Is the Schmitt-trigger input compatible with slow-switching thermistor or potentiometer signals?

Yes - with minimum input transition rate of 10 ns/V at VCC ≥2.7 V, it reliably digitizes signals with rise/fall times up to 100 μs (e.g., RC-filtered sensor outputs). Hysteresis prevents oscillation near threshold, eliminating need for external debouncing circuitry in analog front-end interfacing.

What is the maximum recommended trace length for 74LVC1G125GZ driving a capacitive load?

For CL ≤30 pF (including probe/jig), max trace length is 5 cm on FR-4 with 50 Ω impedance. At 50 pF load, limit to 2 cm to maintain <10% overshoot and t_pd variation <0.5 ns. Always simulate with IBIS model if routing exceeds 3 cm or CL >25 pF.
