Product details
Overview
74LVC1G125GW,125 from Nexperia is a single 3-state bus buffer/line driver with Schmitt-trigger inputs, operating from 1.65 V to 5.5 V supply. It enables level translation between 3.3 V and 5 V logic domains, features ±24 mA output drive at 3.0 V, IOFF circuitry for partial power-down protection, and operates across –40 °C to +125 °C. It is used in mixed-voltage I/O interfacing on microcontroller peripheral buses.
For engineers reviewing the 74LVC1G125GW,125 datasheet, 74LVC1G125GW,125 pinout, 74LVC1G125GW,125 application, or 74LVC1G125GW,125 equivalent, this device supports robust signal integrity in space-constrained industrial control modules, low-power sensor hubs, and automotive body electronics where voltage domain bridging and high noise immunity are required.
Technical Context
The 74LVC1G125GW,125 implements a non-inverting buffer with active-low 3-state enable (OE), enabling bidirectional bus control via external gating. Its Schmitt-trigger inputs accept slow-rising signals up to 10 ns/V transition rate (VCC ≥ 2.7 V), ensuring reliable operation with noisy or RC-filtered sources.
IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±2 μA and preventing damage during hot insertion or partial system power-down. The device complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36 across its full 1.65–5.5 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.65 V to 5.5 V - supports direct interface with both 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| Output Drive | ±24 mA at VCC = 3.0 V - sufficient to drive 15 pF loads with <4.5 ns propagation delay, enabling use in high-speed digital interconnects. |
| Propagation Delay | 0.5–4.5 ns (VCC = 3.0–3.6 V) - ensures sub-5 ns timing margin for 100 MHz clocked data paths in compact embedded systems. |
| IOFF Leakage | ±2 μA at VCC = 0 V - prevents destructive backfeed current during board-level power sequencing or hot-swap events. |
| Input Threshold | VIL ≤ 0.35×VCC, VIH ≥ 0.65×VCC - provides wide noise margin (>0.5 V at 3.3 V) and tolerance to ground bounce or supply ripple. |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive, industrial PLC I/O modules, and extended-temperature IoT edge nodes. |
| ESD Rating | HBM >2000 V, CDM >1000 V - meets IEC 61000-4-2 Level 2 requirements for handling robustness in manufacturing and field service. |
Pinout & Package
TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5-lead, 1.25 mm body width, 0.65 mm pitch, exposed pad not present.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OE (active-low) | 3-state enable input; pulls output Y to high-impedance when HIGH, allowing shared bus arbitration. |
| 2 | A | non-inverting data input; Schmitt-triggered to reject noise on slow-rising control lines. |
| 3 | GND | reference ground for all I/O and internal logic; must be low-inductance connection for stable switching. |
| 4 | Y | buffered, 3-state output; capable of sourcing/sinking ±24 mA while maintaining VOL ≤ 0.55 V / VOH ≥ 2.3 V at 3.0 V. |
| 5 | VCC | primary supply rail; powers internal logic and output stage; decoupling capacitor (100 nF) required within 5 mm. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 1.65–5.5 V operation enables drop-in replacement across legacy and next-gen logic families without redesign. |
| Overvoltage-Tolerant Inputs | Inputs withstand up to 5.5 V regardless of VCC - allows safe interfacing with 5 V peripherals even when powered from 1.8 V. |
| IOFF Partial Power-Down | Outputs disable automatically when VCC = 0 V, eliminating need for external isolation switches in modular power architectures. |
| Schmitt-Trigger Inputs | Input hysteresis >0.3 V at 3.3 V suppresses chatter from slow or noisy signals, reducing false triggering in motor control feedback paths. |
| Low Dynamic Power | CPD = 25 pF (enabled), 6 pF (disabled) - minimizes switching current in battery-powered sensor nodes with burst-mode communication. |
Applications
| Industrial Sensor Interface | Automotive Body Control Module |
|---|---|
Use Scenario: Interfacing analog sensor ADCs with different supply domains (e.g., 5 V sensor, 3.3 V MCU). IC Role / Device Role / Timing Role: Level-translating buffer isolating ADC data lines from MCU GPIO, enabling clean readout during mixed-voltage operation. Use Value: Eliminates need for discrete level-shifter ICs; IOFF prevents backfeed when ADC is powered off while MCU remains active. |

IC Role / Device Role / Timing Role: Output buffer with 3-state control for multiplexed indicator updates and fault-safe shutdown. Use Value: ±24 mA drive supports direct LED driving; Schmitt inputs tolerate noisy chassis-ground-referenced switch inputs. |
| Compact IoT Edge Node | Programmable Logic Controller I/O Expansion |
Use Scenario: Isolating SPI bus segments between low-power host SoC and external flash memory or transceivers. IC Role / Device Role / Timing Role: Bidirectional bus buffer enabling hot-plug detection and dynamic bus segmentation. Use Value: Sub-5 ns propagation delay preserves SPI timing margins at 20 MHz; TSSOP5 footprint saves PCB area in space-constrained modules. |
Use Scenario: Extending digital I/O count on PLC mainboard using daisy-chained shift registers or parallel port expanders. IC Role / Device Role / Timing Role: Signal repeater and voltage translator between 5 V legacy I/O cards and modern 3.3 V controller ASICs. Use Value: JEDEC-compliant operation across 1.65–5.5 V ensures compatibility with legacy and new designs; latch-up immunity >250 mA enhances field reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | Same logic function and pinout; SOT-23-5 package; lower max ambient temp (+85 °C vs. +125 °C); IOFF not specified. | Limited to commercial temperature grade; unsuitable for under-hood or industrial ambient environments. | Select only for cost-sensitive consumer applications where extended temperature range and IOFF are not required. |
| 74AUP1G125GW,125 | Lower static current (0.9 μA vs. 4 μA), wider VCC range (0.8–3.6 V), but no 5 V tolerance; max drive ±4 mA at 3.0 V. | Optimized for ultra-low-power battery operation, not mixed 3.3/5 V translation. | Choose when power budget is critical and 5 V interface capability is unnecessary; avoid if interfacing with 5 V peripherals. |
Compared with SN74LVC1G125DBVR and 74AUP1G125GW,125, the 74LVC1G125GW,125 uniquely combines 5 V-tolerant inputs, IOFF protection, and –40 °C to +125 °C operation in a 5-pin TSSOP, making it the only option qualified for harsh-environment mixed-voltage buffering.

FAQ
Can the 74LVC1G125GW,125 operate with a 1.8 V supply and interface to a 5 V microcontroller?
Yes. Its inputs tolerate up to 5.5 V regardless of VCC, so a 1.8 V-powered 74LVC1G125GW,125 can safely accept 5 V logic inputs. Outputs swing from GND to 1.8 V, requiring an external pull-up or level shifter for 5 V-compatible high levels - but input-side translation is fully supported.
What is the purpose of the IOFF feature, and how does it behave during power sequencing?
IOFF disables the output stage when VCC = 0 V, limiting leakage current to ±2 μA. During power-down, this prevents backflow current from live downstream circuits into the unpowered IC - protecting both the buffer and connected devices in modular or hot-swap systems.
Does the Schmitt-trigger input affect timing parameters like propagation delay?
No. Propagation delay (tpd) is measured between input and output transitions under standard test conditions (VI = 0.5×VCC). Schmitt action only affects input threshold behavior - improving noise immunity without adding delay - as confirmed by Nexperia's tpd specs across all VCC ranges.
Is the TSSOP5 (SOT353-1) package RoHS-compliant and lead-free?
Yes. The 74LVC1G125GW,125 in SOT353-1 packaging is RoHS-compliant and lead-free per Nexperia's product compliance documentation (document ID: "74LVC1G125_125" revision 17.1), with homogeneous material declarations available upon request.
