Product details
Overview
NL17SZ126DFT2G-L22038 from onsemi is a single non-inverting 3-state buffer IC designed for level-shifting and bus isolation in low-voltage digital systems. It operates from 1.65 V to 5.5 V, delivers 2.3 ns typical propagation delay at 5 V, supports 24 mA output drive at 3.0 V, and features IOFF partial power-down protection - used in portable instrumentation signal routing and mixed-voltage microcontroller I/O expansion.
For engineers reviewing the NL17SZ126DFT2G-L22038 datasheet, pinout, applications, or equivalent options, key selection criteria include VCC range compatibility, tri-state enable timing (tPZH/tPHZ), overvoltage-tolerant inputs up to 5.5 V, and SC-88A package footprint constraints for space-constrained PCB layouts.
Technical Context
The NL17SZ126DFT2G-L22038 implements a single-channel non-inverting buffer with active-high 3-state output control (OE pin). Its logic function follows a truth table where output Y mirrors input A when OE = HIGH, and enters high-impedance state when OE = LOW - enabling bidirectional bus sharing without contention.
It integrates IOFF circuitry that disables input/output paths when VCC = 0 V, preventing back-powering and current leakage during partial power-down. Input and output pins tolerate voltages up to 5.5 V independent of VCC, supporting mixed-supply interfacing between 1.8 V, 2.5 V, 3.3 V, and 5 V domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables interoperability across 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| tPD (Typ) | 2.3 ns at VCC = 5 V, RL = 1 MΩ, CL = 15 pF - ensures minimal signal delay in high-speed data path buffering. |
| IOH/IOL | ±24 mA at VCC = 3.0 V - drives standard TTL loads and multiple CMOS inputs without external buffers. |
| Input Voltage Tolerance | Up to 5.5 V - allows safe connection to higher-voltage signals even when powered at 1.65 V. |
| IOFF Leakage | ≤10 µA at VCC = 0 V - prevents cross-talk and power loss in partially powered subsystems. |
| Operating Temp | −55 °C to +125 °C - qualified for industrial and extended-temperature embedded applications. |
| ESD Rating | 2000 V HBM - provides robust handling during board assembly and field service. |
Pinout & Package
Package: SC-88A (Case 419A-02), 5-pin surface-mount, 2.00 mm × 1.25 mm × 0.95 mm body, 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output Enable (active-high) | Controls tri-state output: HIGH enables Y = A; LOW forces Y into high-Z for bus arbitration. |
| 2 (A) | Non-inverting Data Input | Accepts logic-level signals; tolerant to 5.5 V regardless of VCC setting. |
| 3 (GND) | Ground Reference | Primary return path for supply and signal currents; must be low-inductance for noise immunity. |
| 4 (Y) | Buffered Output | Drives downstream logic; exhibits 2.5 pF output capacitance and ≤0.55 V VOL at 24 mA sink. |
| 5 (VCC) | Positive Supply | Power rail for internal logic; supplies output drivers and defines VIH/VIL thresholds. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC Range | 1.65 V to 5.5 V operation supports direct interface with 1.8 V ASICs, 3.3 V FPGAs, and legacy 5 V peripherals. |
| IOFF Protection | Automatically disables I/O paths during VCC = 0 V, eliminating back-current flow in hot-swap or power-gated modules. |
| Overvoltage-Tolerant I/O | Inputs and outputs withstand 5.5 V regardless of VCC - eliminates need for external clamping diodes in mixed-rail designs. |
| Low Propagation Delay | 2.3 ns typical tPD at 5 V enables use in >200 MHz clock distribution and fast control signal buffering. |
| Small Footprint | SC-88A package occupies only 2.5 mm² PCB area - ideal for wearables, sensor nodes, and ultra-compact modules. |
Applications
| Industrial PLC I/O Expansion | Portable Medical Sensor Hub |

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-inverting 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | Same SC-70-5 (SC-88A) package; 3.6 V max VCC; 3.7 ns tPD at 3.3 V; no IOFF. | Lacks partial power-down protection; unsuitable for hot-swap or multi-rail partial-power systems. | Select when cost sensitivity outweighs IOFF requirement and VCC stays ≤3.6 V. |
| 74LVC1G17GW,125 | SC-88A package; Schmitt-trigger input; 3.3 V max VCC; 4.1 ns tPD at 3.3 V; no IOFF. | Input hysteresis improves noise immunity but adds propagation uncertainty; incompatible with 5 V tolerant interfaces. | Choose only for noisy environments with stable 3.3 V supply and no need for overvoltage tolerance. |
Compared with SN74LVC1G125DBVR and 74LVC1G17GW,125, the NL17SZ126DFT2G-L22038 uniquely combines 5.5 V overvoltage tolerance, IOFF, and sub-2.5 ns delay across 1.65–5.5 V - making it the sole option for robust mixed-voltage bus isolation where partial power-down and wide supply range are mandatory.

FAQ
What is the maximum input voltage the NL17SZ126DFT2G-L22038 can tolerate?
The NL17SZ126DFT2G-L22038 accepts input voltages up to 5.5 V on both A and Y pins - independent of VCC level. This overvoltage tolerance allows safe interfacing with higher-voltage logic (e.g., 5 V microcontrollers) even when the device is powered at 1.65 V or 1.8 V, eliminating external clamping components.
Does the NL17SZ126DFT2G-L22038 support partial power-down operation?
Yes, the NL17SZ126DFT2G-L22038 includes IOFF circuitry that automatically disables input and output paths when VCC = 0 V. This prevents current backflow and signal corruption in systems where subsystems power up/down asynchronously - a critical feature for hot-pluggable modules and battery-backed circuits.
What is the typical propagation delay of the NL17SZ126DFT2G-L22038 at 3.3 V supply?
At VCC = 3.3 V, RL = 1 MΩ, and CL = 15 pF, the NL17SZ126DFT2G-L22038 exhibits a typical propagation delay (tPLH/tPHL) of 2.5 ns. This value is confirmed in the AC Electrical Characteristics table on page 5 of the official datasheet and supports reliable operation in high-speed digital interfaces up to ~200 MHz.
Which package does the NL17SZ126DFT2G-L22038 use, and what are its dimensions?
The NL17SZ126DFT2G-L22038 uses the SC-88A (also known as SC-70-5 or SOT-353) package: 2.00 mm × 1.25 mm × 0.95 mm body size with 0.65 mm lead pitch. Pin 1 orientation follows Q4 marking per onsemi's tape-and-reel specification, and the package is RoHS-compliant and Pb-free.
Is the NL17SZ126DFT2G-L22038 qualified for automotive applications?
The base NL17SZ126DFT2G-L22038 is not automotive-qualified, but the pin-compatible NL17SZ126DFT2G-Q variant carries AEC-Q100 qualification and PPAP capability. For automotive body control or infotainment modules requiring temperature-grade reliability, the -Q suffix version must be specified - the L22038 suffix denotes a specific reel lot and does not affect qualification status.
