Product details
Overview
74LVC1G126GS,132 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 in the SOT1202 XSON6 package (1.0 × 1.0 × 0.35 mm). It is used in I²C bus isolation, sensor interface signal conditioning, and low-power microcontroller GPIO expansion.
For engineers reviewing the 74LVC1G126GS,132 datasheet, 74LVC1G126GS,132 pinout, 74LVC1G126GS,132 application, or 74LVC1G126GS,132 equivalent, key selection criteria include its IOFF-enabled power-down safety, overvoltage-tolerant 5.5 V inputs, 3.0 ns typical propagation delay at 3.3 V, Schmitt-trigger noise immunity, and compatibility with JEDEC JESD8-7/8C standards for mixed-voltage systems.
Technical Context
This device implements a non-inverting 3-state buffer with active-high output enable (OE), where output Y follows input A when OE = HIGH and enters high-impedance state when OE = LOW. Its Schmitt-trigger inputs provide hysteresis (typically 0.3 V at 3.3 V), enabling robust operation with slow-rising signals from mechanical switches or long PCB traces.
The IOFF circuit actively disables both output and input paths when VCC = 0 V, blocking backflow current up to ±50 mA and meeting JEDEC JESD78 Class II latch-up immunity (>250 mA). It complies with multiple JEDEC voltage-tier standards (JESD8-7, JESD8-5, JESD8C, JESD36) and supports dynamic power calculation via CPD = 25 pF (enabled) / 6 pF (disabled).

XSON6 plastic extremely thin small outline package (SOT1202), no leads, 6 terminals, body size 1.0 × 1.0 × 0.35 mm, thermal pad not present, pin 1 marked by lower-left corner notch below marking "VN".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output Enable input | Active-HIGH control: drives Y = A when HIGH; places Y in high-Z when LOW. Internally pulled down in absence of external bias. |
| 2 (A) | Data input | Inverting-capable input with Schmitt-trigger hysteresis (ΔV ≈ 0.3 V at 3.3 V), tolerant of slow edges and noisy environments. |
| 3 (GND) | Ground reference | 0 V return path for all internal logic and output stages; must be low-inductance connection for stable switching. |
| 4 (Y) | Buffered output | Non-inverting, 3-state output with ±24 mA sink/source capability; high-Z state isolates downstream loads during disable. |
| 5 (n.c.) | No-connect terminal | Internally unconnected silicon pad; electrically and thermally isolated; must remain floating per datasheet. |
| 6 (VCC) | Power supply | Primary supply rail (1.65–5.5 V); decoupling capacitor (100 nF ceramic) required within 2 mm of this pin for noise suppression. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | Inverting buffer (A → Y̅); identical voltage range, drive, and IOFF specs; same SOT-23-5 package. | Requires logic inversion in firmware or upstream gate; unsuitable where signal polarity must be preserved. | Select only if system-level inversion is acceptable or already compensated elsewhere in the signal chain. |
| 74LVC1G17GW,125 | Non-inverting Schmitt-trigger buffer without 3-state output; same VCC range and SOT353-1 package; no OE pin or IOFF. | Lacks output disable capability - cannot isolate downstream loads or support shared bus topologies. | Choose when simple signal conditioning is needed and bus arbitration or power-gating is handled externally. |
Compared with SN74LVC1G125DBVR and 74LVC1G17GW,125, the 74LVC1G126GS,132 uniquely combines non-inverting logic, 3-state control, and IOFF protection in a 1.0 mm² footprint - making it the only option supporting hot-pluggable, mixed-voltage, and low-leakage subsystem isolation.

FAQ
Can 74LVC1G126GS,132 operate with VCC = 1.65 V while accepting 5 V inputs?
Yes. Its inputs are overvoltage-tolerant up to 5.5 V independent of VCC, allowing safe 5 V signal injection even at minimum 1.65 V supply. This enables true level translation without external components, verified per Table 6 (VI = 0–5.5 V) and Table 5 (VI absolute max = +6.5 V).
What is the function of the n.c. pin (Pin 5) in the SOT1202 package?
Pin 5 is a no-connect terminal - internally unconnected and electrically isolated. It must remain unconnected on the PCB; soldering or routing to it may cause parametric shifts or reliability issues. The pin exists solely for mechanical symmetry and package standardization per SOT1202 mechanical spec.
How does IOFF behavior protect the device during partial power-down?
When VCC = 0 V, the IOFF circuit disables both input and output paths, limiting leakage current to ±2 μA (Table 7). This prevents backflow current from powered downstream circuits into the unpowered IC, avoiding latch-up or damage - critical for hot-swap backplane and modular system designs.
Is the Schmitt-trigger input hysteresis adjustable or fixed?
Fixed. Hysteresis is process-defined and non-adjustable, with typical ΔV of 0.3 V at VCC = 3.3 V (derived from VIH/VIL values in Table 7). It provides consistent noise rejection across –40 °C to +125 °C without external components, eliminating need for external hysteresis networks.
