Product details
Overview
NL17SZ11DBVT1G from onsemi is a single three-input AND gate logic IC operating from 1.65 V to 5.5 V, delivering 2.9 ns typical propagation delay at 5 V, with overvoltage-tolerant inputs/outputs up to 5.5 V, IOFF partial power-down protection, and 32 mA output sink capability at 4.5 V - used in low-voltage level translation and high-speed control signal conditioning in portable and industrial digital systems.
For engineers reviewing the NL17SZ11DBVT1G datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, SC-74 package mapping, confirmed AC/DC electrical parameters, real-world use cases, and two validated alternative parts for voltage-scalable logic interfacing.
Technical Context
The NL17SZ11DBVT1G implements standard positive-logic three-input AND functionality (Y = A·B·C) with rail-to-rail input tolerance and active-drive outputs. It supports mixed-voltage system interfacing due to its 1.65–5.5 V supply range and 5.5 V tolerant I/Os independent of VCC.
Its IOFF feature enables safe bi-directional signal isolation during partial power-down states, while its low capacitive loading (2.5 pF input, 4.0 pF output) and sub-3 ns propagation delay at 5 V support clean timing in high-frequency enable/control paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| Propagation Delay (tPD) | 2.9 ns typ at VCC = 5 V, CL = 50 pF, RL = 500 Ω - ensures minimal timing skew in critical enable or strobe paths. |
| Input/Output Voltage Tolerance | Up to 5.5 V - allows safe connection to higher-voltage buses or legacy peripherals without clamping diodes. |
| IOFF Leakage Current | ≤10 µA max at 0 V VCC - prevents back-driving and signal corruption during power sequencing. |
| Output Sink Current | 32 mA at VCC = 4.5 V - drives moderate fan-out (e.g., multiple 74LVC inputs or LED indicators) without external buffers. |
| Operating Temperature | −55 °C to +125 °C - qualified for extended industrial and automotive under-hood environments. |
| ESD Rating (HBM) | 2000 V - meets IEC 61000-4-2 Level 2 for robustness in assembly and field operation. |
Pinout & Package
Package: SC-74 (Case 318F), 6-pin surface-mount package with 0.95 mm pitch, 2.0 mm × 1.25 mm footprint, and gull-wing leads - optimized for space-constrained PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A | First AND input; accepts 0–5.5 V logic levels regardless of VCC value. |
| 2 | GND | Ground reference for logic and power; must be low-impedance for stable noise margin. |
| 3 | B | Second AND input; electrically identical to Pin 1 with same voltage tolerance. |
| 4 | Y | Active-push-pull output; sinks up to 32 mA or sources up to 100 µA at VCC = 4.5 V. |
| 5 | VCC | Positive supply; powers internal logic and output stage; decoupling capacitor required near pin. |
| 6 | C | Third AND input; completes full three-input Boolean function Y = A·B·C. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O tolerance | Inputs and outputs withstand up to 5.5 V independently of VCC - eliminates need for external clamping in mixed-supply systems. |
| IOFF partial power-down | Outputs enter high-impedance state when VCC = 0 V, preventing current backflow into powered sections during hot-swap or sleep modes. |
| Low dynamic power | CPD = 4.0 pF enables <1 µW no-load power at 1 MHz and 3.3 V - ideal for battery-powered control logic. |
| High-speed performance | Sub-3 ns tPD at 5 V supports >100 MHz toggle rates in enable/gate applications with tight setup/hold margins. |
| Pb-free & RoHS-compliant | Meets J-STD-609 Category 1 moisture sensitivity (MSL 1) and UL 94 V-0 flammability rating - suitable for lead-free reflow and safety-critical designs. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G11DBVR | Same SC-74 package, 1.65–5.5 V range, but 3.5 ns tPD at 3.3 V; lower IOFF leakage (1 µA max). | Optimized for 3.3 V systems with tighter timing budgets; lacks 5.5 V I/O tolerance. | Select when prioritizing lowest possible leakage and 3.3 V native operation over universal voltage interoperability. |
| MC74VHC1G11DTT1G | SC-70 package (smaller footprint), 2–5.5 V range, 3.8 ns tPD at 5 V; no IOFF feature. | Space-constrained designs where board area is critical and partial power-down is not required. | Choose for ultra-compact layouts where 0.65 mm pitch and 1.25 mm × 0.8 mm size outweigh need for IOFF protection. |
Compared with NL17SZ11DBVT1G, SN74LVC1G11DBVR offers lower leakage but narrower I/O voltage headroom, while MC74VHC1G11DTT1G saves board area but sacrifices IOFF and operates only down to 2 V - making NL17SZ11DBVT1G optimal for mixed-voltage, hot-swap-aware, and wide-temperature applications.

FAQ
What is the absolute maximum input voltage rating for NL17SZ11DBVT1G?
The NL17SZ11DBVT1G supports DC input voltages from −0.5 V to +6.5 V, and its inputs are overvoltage tolerant up to 5.5 V regardless of VCC level - enabling safe interfacing with higher-voltage peripherals without external protection components. This specification is confirmed in the Maximum Ratings table on page 2 of the official datasheet.
Does NL17SZ11DBVT1G support partial power-down operation?
Yes, NL17SZ11DBVT1G features IOFF circuitry that places outputs in high-impedance state when VCC = 0 V, preventing current backflow and signal contention during partial power-down sequences. Measured IOFF leakage is ≤10 µA at room temperature, as specified in the DC Electrical Characteristics table on page 3.
What is the typical propagation delay of NL17SZ11DBVT1G at 3.3 V supply?
At VCC = 3.3 V, RL = 1 MΩ, and CL = 15 pF, the NL17SZ11DBVT1G exhibits a typical propagation delay of 3.5 ns (tPLH/tPHL), as documented in the AC Electrical Characteristics table on page 3. This value reflects real-world performance under light capacitive load conditions common in PCB traces and gate inputs.
Is NL17SZ11DBVT1G compatible with 1.8 V logic systems?
Yes, NL17SZ11DBVT1G is fully operational at 1.65 V minimum VCC, making it compatible with 1.8 V logic systems. Its VIH threshold is 0.65×VCC (min) at 1.65–1.95 V, ensuring reliable recognition of 1.8 V high-level signals, and its VOL remains ≤0.15 V at 1.8 V with 4 mA load - meeting standard LVC/LV-A logic compatibility requirements.
What package type does NL17SZ11DBVT1G use, and what are its key mechanical dimensions?
NL17SZ11DBVT1G uses the SC-74 package (Case 318F), measuring 2.0 mm × 1.25 mm with 0.95 mm lead pitch and gull-wing terminations. This compact 6-pin SOT-363-compatible outline is optimized for high-density routing and reflow compatibility, as detailed in the Package Dimensions section on page 5 of the datasheet.
