Product details
Overview
74LVC1G126GW,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, supporting mixed-voltage translation between 3.3 V and 5 V systems, delivering ±24 mA output drive at 3.0 V, and specified for -40 °C to +125 °C industrial operation.
For engineers reviewing the 74LVC1G126GW,125 datasheet, 74LVC1G126GW,125 pinout, 74LVC1G126GW,125 application, or 74LVC1G126GW,125 equivalent, this device serves as a low-power, voltage-tolerant interface for I/O expansion, level-shifting in microcontroller peripheral buses, and bidirectional signal conditioning in space-constrained embedded control modules.
Technical Context
The 74LVC1G126GW,125 implements a non-inverting buffer with active-high 3-state enable (OE), enabling precise control of signal flow on shared data lines. Its Schmitt-trigger inputs tolerate slow-rising signals and improve noise immunity in noisy industrial environments.
IOFF circuitry ensures safe partial power-down operation by disabling outputs and blocking backflow current when VCC = 0 V, meeting JEDEC JESD8-7/5/C/36 compliance across 1.65–5.5 V supply ranges and supporting direct TTL-level interfacing without external biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables direct use in 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive 15 pF loads with <6 ns propagation delay and maintain signal integrity over PCB traces. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - Allows 5 V inputs to be safely accepted while powered from 1.65–3.3 V supplies. |
| Propagation Delay | 0.5–4.5 ns (VCC = 3.0–3.6 V) - Supports high-speed digital interfaces up to ~200 MHz clock-equivalent timing. |
| IOFF Leakage Current | ±2 μA at VCC = 0 V - Prevents damaging backfeed current during hot-swap or partial system power-down sequences. |
| Operating Temperature | -40 °C to +125 °C - Qualified for under-hood automotive, industrial motor control, and outdoor IoT edge nodes. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - Reduces field failure risk in manual handling and unshielded board assembly environments. |
Pinout & Package
TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5-lead, 1.25 mm body width, 0.65 mm lead pitch, exposed padless construction optimized for reflow soldering and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OE | Output Enable input | Active-HIGH control: drives Y to high-impedance when LOW; enables buffered A→Y pass-through when HIGH. |
| 2 - A | Data input | Non-inverting input with Schmitt-trigger hysteresis (typ. 0.3 V at 3.3 V) - rejects noise on slow-rising control or sensor signals. |
| 3 - GND | Ground reference | 0 V return path for all internal logic and output drivers; must be low-impedance to minimize ground bounce. |
| 4 - Y | 3-state output | Buffered, non-inverted copy of A when OE = HIGH; high-Z (≥10 MΩ) when OE = LOW - isolates downstream bus segments. |
| 5 - VCC | Power supply | Primary supply rail (1.65–5.5 V); powers all logic and output stages; requires local 100 nF ceramic decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 1.65 V to 5.5 V operation enables drop-in replacement across legacy and modern logic families without redesign. |
| Overvoltage-Tolerant Inputs | Accepts 5.5 V inputs regardless of VCC level - eliminates need for external clamping diodes in mixed-voltage interconnects. |
| IOFF Partial Power-Down | Automatically disables outputs and blocks reverse current when VCC = 0 V - critical for hot-plug and modular system architectures. |
| Schmitt-Trigger Inputs | Provides ≥0.3 V hysteresis at 3.3 V - stabilizes switching against EMI, crosstalk, and long trace ringing in industrial control wiring. |
| JEDEC Compliance | Fully conforms to JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), JESD8C (2.7–3.6 V), and JESD36 (4.5–5.5 V) - guarantees interoperability in multi-supply systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G126DBVR | TI part in SOT-23-5 package; identical 1.65–5.5 V range and ±24 mA drive but lacks IOFF specification at VCC = 0 V. | Not qualified for partial power-down scenarios requiring backflow prevention; limited to full-system power sequencing. | Select only if system never operates with VCC = 0 V while inputs remain active. |
| 74AUP1G126GW,125 | Nexperia AUP variant in same TSSOP5 package; lower ICC (0.9 μA typ), wider temp range (-40 °C to +125 °C), but reduced drive (±4 mA at 3.0 V). | Better suited for ultra-low-power sensor nodes than high-drive bus termination; propagation delay increases to 11 ns at 1.8 V. | Prefer for battery-powered edge devices where drive strength <8 mA suffices and quiescent current is critical. |
Compared with SN74LVC1G126DBVR and 74AUP1G126GW,125, the 74LVC1G126GW,125 uniquely balances industrial-grade IOFF protection, 24 mA drive, and 125 °C operation in a 5-pin TSSOP - making it optimal for safety-critical partial-power-down systems where both robustness and performance are required.

FAQ
What is the maximum input voltage the 74LVC1G126GW,125 can tolerate when VCC = 1.8 V?
The device accepts inputs up to 5.5 V regardless of VCC level, as confirmed in Table 5 (Limiting Values) and Table 6 (Recommended Operating Conditions). This overvoltage tolerance allows safe connection of 5 V signals to a 1.8 V-powered buffer without external clamping components.
Does the 74LVC1G126GW,125 support hot-swap insertion into a live backplane?
Yes - its IOFF circuitry actively disables outputs and blocks reverse current when VCC = 0 V, satisfying hot-swap safety requirements. Per Section 1, IOFF leakage is limited to ±2 μA under these conditions, preventing damage to upstream drivers or bus contention.
How does the Schmitt-trigger input improve noise immunity in industrial settings?
Schmitt-trigger action provides hysteresis (~0.3 V at 3.3 V), meaning the input threshold rises after a HIGH transition and falls after a LOW transition. This prevents multiple toggles caused by slow edges or noise spikes on long cables or unshielded harnesses common in factory automation environments.
Can the 74LVC1G126GW,125 drive a 50 pF load at 10 MHz while maintaining signal integrity?
Yes - with typical propagation delay of 2.0 ns and output drive of ±24 mA at 3.0 V, the device delivers rise/fall times <2.5 ns into 50 pF (per Table 10 test conditions), ensuring clean edges and minimal jitter at 10 MHz clock rates in standard PCB layouts.
