Product details
Overview
NC7SZ126L6X-L22175 from onsemi is a single ultra-high-speed CMOS buffer with three-state output, designed for level translation and bus isolation in space-constrained digital systems. It operates across 1.65 V to 5.5 V VCC, delivers ±24 mA output drive at 3 V, and achieves 2.6 ns typical propagation delay into 50 pF at 5 V - enabling high-speed signal routing in portable and low-power logic interfaces.
For engineers reviewing the NC7SZ126L6X-L22175 datasheet, pinout, applications, or equivalent options, key selection criteria include its over-voltage-tolerant inputs (up to 5.5 V independent of VCC), power-down high-impedance behavior at VCC = 0 V, and compatibility with 1.8 V/2.5 V/3.3 V/5 V mixed-supply systems.
Technical Context
The NC7SZ126L6X-L22175 implements a non-inverting buffer with active-low three-state enable (OE), supporting bidirectional bus control via output disable. Its input structure tolerates 5.5 V regardless of VCC, enabling robust 5 V-to-3.3 V or 5 V-to-1.8 V level translation without external components.
It features proprietary noise/EMI reduction circuitry and operates reliably from −40 °C to +85 °C. The device enters high-impedance state when OE is low, and maintains input/output high-impedance when VCC = 0 V - critical for hot-swap and power-gating applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports interoperability across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| tPD (Typ) | 2.6 ns into 50 pF at 5 V - enables sub-400 MHz signal routing in compact logic paths |
| Output Drive | ±24 mA at 3 V - drives multiple LVTTL/LVCMOS loads without buffering |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - eliminates need for external level shifters in mixed-voltage buses |
| IOFF (Power-Off Leakage) | ≤10 µA at VIN/VOUT = 5.5 V, VCC = 0 V - prevents back-powering and ensures safe hot-insertion |
| Quiescent ICC | ≤20 µA - minimizes static power in always-on logic monitoring circuits |
| CIN | 4 pF - reduces capacitive loading on driving gates, preserving signal integrity |
Pinout & Package
SIP6 (MicroPak) package: 1.45 mm × 1.0 mm, 0.5 mm pitch, 6-pin ultra-thin leadless package with exposed thermal pad (Case 127EB). Pin 5 is no-connect (NC); pin 6 is VCC. Compatible with reflow soldering and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OE (Active-Low Enable) | Controls three-state output: LOW disables Y, HIGH enables non-inverting pass-through of A |
| 2 | A (Input) | Buffer input; accepts 5.5 V max regardless of VCC; must be driven HIGH or LOW (no floating) |
| 3 | GND | Ground reference for logic and power; connects to PCB ground plane for noise immunity |
| 4 | Y (Output) | Three-state buffered output; tolerates up to 5.5 V in high-impedance mode |
| 5 | NC | No internal connection; left unconnected on PCB; no routing or stitching required |
| 6 | VCC | Supply voltage input (1.65–5.5 V); requires local 100 nF ceramic decoupling capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-High Speed | 2.6 ns tPD (typ) at 5 V enables timing-critical signal conditioning in FPGA I/O expansion |
| Over-Voltage Tolerant Inputs | 5.5 V input rating independent of VCC allows direct interfacing with legacy 5 V peripherals |
| Power-Down High-Z | Inputs/outputs go high-impedance when VCC = 0 V - essential for hot-plug and battery-backed subsystems |
| Low Dynamic Power | CPD = 17 pF at 3.3 V - reduces switching current and EMI in high-frequency clock/data paths |
| Pb-Free & RoHS Compliant | Made with halogen-free/BFR-free materials and qualified for industrial temperature range (−40 °C to +85 °C) |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer-with-three-state-output applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | 5-pin SOT-23 package; 1.65–5.5 V; tPD = 3.7 ns (typ) at 3.3 V; no 5.5 V input tolerance | Lacks over-voltage input capability; requires external clamping for 5 V signal sources | Preferred where board space permits larger SOT-23 and system uses only 3.3 V or lower I/O |
| 74LVC1G17GW,125 | 6-pin SC-88 package; 1.65–5.5 V; Schmitt-trigger input; tPD = 4.4 ns (typ); no 5.5 V input tolerance | Provides hysteresis for noisy environments but cannot accept 5 V inputs directly | Select when input signal edges are slow or noisy, and voltage translation is handled elsewhere |
Compared with SN74LVC1G125DBVR and 74LVC1G17GW,125, the NC7SZ126L6X-L22175 uniquely combines 5.5 V input tolerance, 2.6 ns speed, and SIP6 footprint - making it optimal for miniaturized mixed-voltage systems requiring zero external components for level translation.

FAQ
What is the maximum input voltage the NC7SZ126L6X-L22175 can tolerate?
The NC7SZ126L6X-L22175 supports DC input voltages up to 5.5 V regardless of VCC level - a key feature enabling direct connection to 5 V sources even when powered from 1.8 V or 2.5 V. This eliminates external level-shifting components and simplifies mixed-voltage interface design. Absolute maximum rating is 6.5 V, but operation above 5.5 V is not guaranteed.
Does the NC7SZ126L6X-L22175 support hot-swap or power-gating scenarios?
Yes. When VCC = 0 V, both inputs and outputs of the NC7SZ126L6X-L22175 enter a high-impedance state with ≤10 µA power-off leakage current. This prevents back-powering of upstream circuits and ensures safe insertion/removal in live backplanes or modular systems - a critical capability confirmed in the datasheet's "Power Down High-Impedance Inputs/Outputs" feature.
What is the function of Pin 5 (NC) on the NC7SZ126L6X-L22175 SIP6 package?
Pin 5 on the NC7SZ126L6X-L22175 is designated as "No Connect" (NC) - it has no internal connection to die circuitry and must remain unconnected on the PCB. Neither routing nor grounding is required. This pin exists for mechanical symmetry and package standardization, not electrical functionality.
Can the NC7SZ126L6X-L22175 drive a 50 pF load at 100 MHz?
The NC7SZ126L6X-L22175 is characterized for AC performance into 50 pF loads, with tPD = 2.6 ns (typ) at 5 V and tPZH/tPHZ < 6 ns. While it can drive such loads, sustained 100 MHz toggling requires verifying dynamic power (ICCD = CPD × VCC × fIN) and thermal dissipation - especially in SIP6's 154 °C/W θJA. For continuous 100 MHz operation, ensure adequate PCB copper pour and ambient ≤70 °C.
Is the NC7SZ126L6X-L22175 RoHS compliant and lead-free?
Yes. The NC7SZ126L6X-L22175 is explicitly marked Pb-Free and complies with RoHS Directive 2011/65/EU. It is also halogen-free and BFR-free, as stated in the "Features" section of the official datasheet (Rev. 8, August 2024). The "M" suffix in marking and packaging documentation confirms lead-free construction.
