Product details
Overview
NC7WZ125L8X from Fairchild Semiconductor is a dual non-inverting buffer IC with independent active-low 3-STATE enable inputs, fabricated in advanced CMOS for ultra-high-speed operation (2.6 ns typical propagation delay at 5V), ±24 mA output drive at 3V, and broad 1.65V–5.5V supply range - used in voltage-level translation and bus isolation in portable logic systems.
For engineers reviewing the NC7WZ125L8X datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, MicroPak package details, functional pin mapping, real-world use cases, and two validated alternative parts for logic interface design.
Technical Context
The NC7WZ125L8X implements two independent buffer channels, each with dedicated active-low OE input controlling 3-STATE output state. Its architecture supports bidirectional voltage translation: inputs tolerate up to 5.5V regardless of VCC, and outputs remain overvoltage-tolerant (0–5.5V) in high-impedance mode.
It operates across industrial temperature (−40°C to +85°C) with guaranteed AC performance into 50 pF loads, including tPLH/tPHL ≤ 5.3 ns at 3.3V and ≤ 4.8 ns at 5V, plus sub-nanosecond output skew (tOSLH/tOSHL ≤ 1.0 ns), enabling precise timing in multi-channel digital interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - enables single-supply operation across 1.8V, 2.5V, 3.3V, and 5V logic domains |
| tPD (Typ) | 2.6 ns at 5V into 50 pF - ensures minimal signal delay in high-speed data paths |
| IOUT Drive | ±24 mA at 3V - supports driving moderate capacitive loads without external buffers |
| Input Tolerance | 0V to 5.5V independent of VCC - allows safe 5V-to-3V translation without level shifters |
| 3-STATE Output Range | 0V to 5.5V - maintains compatibility with mixed-voltage buses during disable |
| Operating Temp | −40°C to +85°C - qualified for industrial-grade embedded control and portable electronics |
Pinout & Package
Pb-Free 8-pin MicroPak package (JEDEC MO-255, variation UAAD), 1.6 mm wide, leadless, bottom-terminal land pattern with exposed die pad - requires solder paste stencil optimization and reflow profile validation per JEDEC J-STD-020B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Input Channel 1 | Non-inverting data input for first buffer; accepts 0–5.5V regardless of VCC |
| 2 (OE1) | Enable Input 1 | Active-low control for Y1 output; pulls Y1 to high-Z when HIGH |
| 3 (Y1) | Output Channel 1 | 3-STATE non-inverting output; drives or floats based on OE1 state |
| 4 (GND) | Ground | Reference for all signals and power return path |
| 5 (VCC) | Supply Voltage | Primary power rail (1.65–5.5V); powers internal logic and output drivers |
| 6 (A2) | Input Channel 2 | Non-inverting data input for second buffer; electrically identical to A1 |
| 7 (OE2) | Enable Input 2 | Active-low control for Y2 output; independent of OE1 for channel gating |
| 8 (Y2) | Output Channel 2 | 3-STATE non-inverting output; fully isolated from Y1 in timing and drive |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 3-STATE control | Enables selective bus isolation per channel without shared enable logic |
| Overvoltage-tolerant inputs | Eliminates need for external clamping diodes when interfacing 5V peripherals to 3.3V/1.8V controllers |
| High-output-drive capability | ±24 mA at 3V supports direct connection to multiple CMOS inputs or small capacitive traces |
| Power-down high-impedance I/O | Inputs and outputs float safely at VCC = 0V - prevents backfeeding in hot-swap or power-gated systems |
| Ultra-low propagation skew | ≤1.0 ns between Y1/Y2 outputs ensures synchronized channel timing in parallel data paths |
Applications
| USB Peripheral Interface | Low-Power Sensor Hub |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer with 3-STATE applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G125DCUR | Same 8-pin VSSOP package; slightly higher ICC (10 µA vs. 1 µA typ), identical VCC range and 3-STATE behavior | TI part offers tighter VOL/VOL specs at 3.3V but lacks 5.5V input tolerance | Select when lower static current is critical and input voltage stays within VCC+0.3V |
| 74LVC2G125GW,125 | NXP's 8-pin XSON package; 1.65–5.5V VCC, 5.5V-tolerant inputs, but tPD = 3.7 ns (slower than NC7WZ125L8X's 2.6 ns) | Better thermal resistance (θJA = 210°C/W vs. 250°C/W), suited for dense layouts with limited airflow | Choose when board space is constrained and thermal performance outweighs speed priority |
Compared with SN74LVC2G125DCUR and 74LVC2G125GW,125, the NC7WZ125L8X delivers the fastest propagation delay (2.6 ns), lowest quiescent current (1 µA typ), and widest input voltage tolerance (0–5.5V) - making it optimal for battery-powered, mixed-voltage, and timing-critical logic interfaces.

FAQ
What is the maximum operating frequency supported by the NC7WZ125L8X?
The NC7WZ125L8X does not specify a maximum clock frequency in its datasheet because it is a combinational buffer, not a clocked device. Its usable frequency limit depends on propagation delay and load capacitance: with tPD = 2.6 ns (typ) at 5V into 50 pF, it supports clean signal transmission up to ~200 MHz for short traces and light loads. For reliable operation, ensure input rise/fall times meet datasheet limits (e.g., ≤10 ns/V at 3.3V).
Can the NC7WZ125L8X be used for 5V-to-3.3V level translation?
Yes, the NC7WZ125L8X supports 5V-to-3.3V level translation when powered at VCC = 3.3V. Its inputs tolerate up to 5.5V regardless of supply voltage, allowing 5V signals to be safely applied. Outputs swing from 0V to VCC (3.3V), providing valid 3.3V logic levels. No external components are needed - just tie OE pins LOW to enable and ensure proper decoupling.
Is the NC7WZ125L8X pin-compatible with the NC7WZ125K8X?
No, the NC7WZ125L8X and NC7WZ125K8X are not pin-compatible. The NC7WZ125L8X uses the Pb-Free MicroPak package (MAC08A, 1.6 mm wide, bottom terminals), while the NC7WZ125K8X uses the US8 package (MAB08A, 3.1 mm wide, gull-wing leads). Their land patterns, soldering methods, and mechanical footprints differ significantly - PCB layout must be redesigned for each.
Does the NC7WZ125L8X require external pull-up or pull-down resistors on its inputs or outputs?
No, the NC7WZ125L8X does not require external pull-up or pull-down resistors on inputs or outputs under normal operation. Inputs have negligible leakage (±0.1 µA typ), and floating inputs are discouraged per datasheet Note 3. However, if an input must be held static when unused, tie it directly to VCC or GND - no resistor needed due to CMOS input structure. Outputs in 3-STATE mode present high impedance and should not be left floating on shared buses without external termination.
What is the thermal resistance (θJA) of the NC7WZ125L8X in its MicroPak package?
The NC7WZ125L8X in the MicroPak package (MAC08A) has a junction-to-ambient thermal resistance (θJA) of 250°C/W, as specified in the Absolute Maximum Ratings table. This value assumes standard JEDEC test conditions (single-layer board, no copper pour). Actual θJA improves significantly with PCB copper area under the exposed pad - adding thermal vias and a solid ground plane can reduce effective θJA by 30–50% in production layouts.
