Product details
Overview
74LVC1G126GM,132 from Nexperia is a single 3-state bus buffer/line driver with Schmitt-trigger inputs, IOFF partial power-down support, and overvoltage-tolerant inputs up to 5.5 V. It operates from 1.65 V to 5.5 V, delivers ±24 mA output drive at 3.0 V, and functions across –40 °C to +125 °C - enabling level translation between 3.3 V and 5 V logic domains in space-constrained industrial I/O interfaces.
For engineers reviewing the 74LVC1G126GM,132 datasheet, 74LVC1G126GM,132 pinout, 74LVC1G126GM,132 application, or 74LVC1G126GM,132 equivalent, this device serves as a low-power, high-noise-immunity unidirectional buffer for mixed-voltage microcontroller GPIO expansion, sensor interface isolation, and FPGA peripheral bus conditioning where compact XSON6 packaging and guaranteed 3-state behavior during power sequencing are critical.
Technical Context
This device implements a single non-inverting buffer with active-high 3-state output control (OE), enabling bidirectional bus sharing via external logic coordination. Its Schmitt-trigger inputs accept slow-rising signals (Δt/ΔV down to 10 ns/V at VCC ≥ 2.7 V) and tolerate input voltages beyond VCC - essential for robust interfacing with legacy 5 V peripherals in modern low-voltage systems.
The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current and preventing damage during hot-insertion or partial system power-down. Static leakage remains below ±2 μA under power-off conditions, meeting JEDEC JESD8-7/8C/36 compliance 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 connection to 1.8 V, 2.5 V, 3.3 V, and 5 V rails without level shifters. |
| Input Voltage Range | –0.5 V to 5.5 V - enables safe interfacing with 5 V TTL outputs even when powered from 1.8 V. |
| Output Drive | ±24 mA at VCC = 3.0 V - sufficient to drive 15 pF loads with <6 ns propagation delay and maintain signal integrity on PCB traces. |
| Propagation Delay | 0.5–4.5 ns (VCC = 3.0–3.6 V) - ensures timing-critical data paths meet setup/hold requirements in high-speed digital subsystems. |
| IOFF Leakage | ±2 μA max at VCC = 0 V - prevents disruptive current flow during power sequencing in multi-rail embedded systems. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O cards, and outdoor edge-node hardware. |
| ESD Protection | HBM >2000 V, CDM >1000 V - withstands handling and board-level ESD events without latch-up or parametric shift. |
Pinout & Package
XSON6 plastic extremely thin small outline package (SOT886); no leads; 6 terminals; body dimensions 1.0 mm × 1.45 mm × 0.5 mm; thermal pad not present; side-wettable flanks absent; pin 1 index located at lower-left corner beneath marking code "VN".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output enable input | Active-high control: drives Y to high-impedance when LOW; must be pulled HIGH or driven to enable buffer function. |
| 2 (A) | Data input | Non-inverting input with Schmitt-trigger hysteresis - accepts slow edges and rejects noise spikes ≥150 mV. |
| 3 (GND) | Ground reference | 0 V return path for all internal logic and output stages; requires low-inductance connection to system ground plane. |
| 4 (Y) | Data output | 3-state buffered output; sinks or sources up to ±24 mA; high-impedance state isolates downstream loads during OE = LOW. |
| 5 (n.c.) | No-connect terminal | Internally unconnected; must remain floating - no external biasing or routing permitted. |
| 6 (VCC) | Supply voltage | Primary power rail; decoupling capacitor (100 nF ceramic) required within 2 mm of this pin for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 1.65–5.5 V operation eliminates need for external voltage translators in mixed-supply systems. |
| Overvoltage-tolerant inputs | Accepts 5.5 V inputs regardless of VCC - enables direct connection to 5 V sensors or legacy controllers while powered from 1.8 V. |
| IOFF partial power-down | Blocks backflow current when VCC = 0 V - protects powered subsystems during hot-swap or staged power-up sequences. |
| Schmitt-trigger inputs | Provides ≥150 mV hysteresis - suppresses false triggering from noisy or slow-rising signals in industrial environments. |
| Low dynamic power | CPD = 25 pF enabled / 6 pF disabled - reduces switching current in battery-powered applications with frequent bus activity. |

FAQ
Can 74LVC1G126GM,132 operate with VCC = 1.65 V while accepting 5 V inputs?
Yes. The device features overvoltage-tolerant inputs rated to 5.5 V independent of VCC, allowing safe 5 V signal reception even at minimum 1.65 V supply. Input thresholds scale with VCC (e.g., VIH = 0.65×VCC at 1.65 V), ensuring reliable logic recognition without external clamping.
What is the purpose of the n.c. pin (Pin 5) in the XSON6 package?
Pin 5 is internally unconnected and must remain electrically floating - no external connection, pull-up, or pull-down is permitted. This terminal exists solely for mechanical symmetry and package standardization; routing or biasing it risks violating the device's absolute maximum ratings and may cause parametric drift.
How does IOFF functionality protect the device during partial power-down?
When VCC = 0 V, the IOFF circuit disables both input and output buffers, limiting leakage current to ±2 μA maximum. This prevents reverse current flow from powered downstream circuits into the unpowered IC - eliminating risk of latch-up, overheating, or corruption of active subsystems during staged power cycling.
Is the 74LVC1G126GM,132 compatible with PCB assembly processes using lead-free reflow profiles?
Yes. The XSON6 (SOT886) package is qualified for standard lead-free reflow per JEDEC J-STD-020, with peak temperatures up to 260 °C. Its 0.5 mm pitch and coplanar terminals support automated optical inspection (AOI) and X-ray void detection, ensuring high first-pass yield in high-volume SMT lines.
