Product details

Overview

NL17SZ32DFT2GH from onsemi is a single 2-input OR gate logic IC in SC-88A (SOT-353) package, operating from 1.65 V to 5.5 V, with 2.4 ns typical propagation delay at 5.0 V, ±24 mA output drive at 3.0 V, and over-voltage tolerant inputs. It serves as a high-speed level-shifting combinatorial logic element in portable power management and interface signal conditioning circuits.

For engineers reviewing the NL17SZ32DFT2GH datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, validated pin functions, confirmed automotive-grade alternatives, and precise package-level design guidance for low-voltage logic interfacing.

Technical Context

The NL17SZ32DFT2GH implements standard positive-logic OR functionality using CMOS technology optimized for low-voltage operation down to 1.65 V. Its input structure supports over-voltage tolerance up to 7.0 V independent of V_CC, enabling safe interfacing with higher-voltage signals in mixed-supply systems.

It delivers rail-to-rail output swing with guaranteed VOH ≥ V_CC − 0.1 V and VOL ≤ 0.42 V at I_OL = 24 mA (V_CC = 3.0 V), and exhibits 4 pF typical input capacitance and 25–30 pF dynamic power dissipation capacitance across 3.3 V and 5.5 V supply conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65 V to 5.5 V - Enables direct use in 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters.
t_PD (typ)	2.4 ns at V_CC = 5.0 V - Supports >200 MHz toggle rates in short-path combinational logic chains.
I_OH/I_OL	±24 mA at V_CC = 3.0 V - Drives multiple 74LVC inputs or small LED loads directly.
V_IN Max	−0.5 V to +7.0 V - Allows connection to 5 V or 3.3 V signals even when V_CC = 1.8 V, eliminating external clamping diodes.
Operating Temp	−55 °C to +125 °C - Qualified for extended industrial and under-hood automotive environments.
Input Capacitance	4 pF - Minimizes loading on preceding drivers and preserves signal edge integrity in high-speed routing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 2-input OR gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NC7SZ32P5X	Identical pinout, same SC-70-5 package, 2.5 ns t_PD at 5 V, 24 mA drive, but rated only to +85 °C commercial temp range.	Lacks extended temperature and automotive qualification; not suitable for under-hood or industrial deployments.	Select NC7SZ32P5X only for cost-sensitive consumer electronics where −40 °C to +85 °C suffices.
TC7SZ32FU	Same pinout and logic function; 3.0 ns t_PD at 5 V; 16 mA drive at 3.3 V; operates from 1.65 V to 6.0 V; JEDEC-standard SOT-353 package.	Higher V_CC max (6.0 V) but lower output drive; no AEC-Q100 variant available.	Prefer TC7SZ32FU when interfacing with legacy 6 V systems or where Toshiba's long-term supply assurance is prioritized.

Compared with NC7SZ32P5X and TC7SZ32FU, the NL17SZ32DFT2GH provides superior thermal ruggedness (−55 °C to +125 °C), stronger output drive at low V_CC, and a qualified automotive path via NLV prefix-making it the optimal choice for mission-critical embedded control nodes.

FAQ

What is the maximum input voltage rating for NL17SZ32DFT2GH?

The NL17SZ32DFT2GH supports DC input voltages from −0.5 V to +7.0 V, independent of V_CC. This over-voltage tolerance allows safe interfacing with 5 V or 3.3 V signals even when powered from 1.8 V, eliminating the need for external clamping diodes or level translators in mixed-supply designs. The specification is validated per absolute maximum ratings in the official onsemi datasheet Rev. 13.

Does NL17SZ32DFT2GH support automotive qualification?

The NL17SZ32DFT2GH itself is not AEC-Q100 qualified; however, its pin-compatible automotive-grade variant NLV17SZ32DFT2G is fully AEC-Q100 qualified and PPAP capable. Both share identical SC-88A packaging, pinout, logic function, and electrical specifications except for extended process controls and traceability required for automotive deployment. Designers may prototype with NL17SZ32DFT2GH and migrate to NLV17SZ32DFT2G for production.

What is the typical propagation delay of NL17SZ32DFT2GH at 3.3 V supply?

At V_CC = 3.3 V, the NL17SZ32DFT2GH exhibits a typical propagation delay (t_PLH/t_PHL) of 4.7 ns under RL = 1 MΩ and CL = 15 pF conditions, as specified in the AC Electrical Characteristics table of the datasheet. This value is measured with 3.0 ns input rise/fall times and confirms the device's suitability for sub-100 MHz logic path timing in compact embedded systems.

Can NL17SZ32DFT2GH drive multiple 74LVC inputs directly?

Yes, NL17SZ32DFT2GH can drive multiple 74LVC inputs directly: at V_CC = 3.3 V, it sources/sinks up to ±24 mA while maintaining VOH ≥ 2.7 V and VOL ≤ 0.42 V, exceeding the 74LVC family's VIH min (2.0 V) and VIL max (0.8 V) thresholds. With typical 74LVC input leakage < ±1 μA and C_IN ≈ 4 pF, a single NL17SZ32DFT2GH output can reliably drive ≥10 standard 74LVC inputs without signal degradation.

What package type does NL17SZ32DFT2GH use, and is it compatible with standard SOT-353 footprints?

NL17SZ32DFT2GH uses the SC-88A package (also known as SC-70-5 or SOT-353), with 0.65 mm lead pitch, 1.9 mm × 1.3 mm body size, and case number 419A-02. It is fully compatible with industry-standard SOT-353 footprints and reflow profiles, including IPC-7351B "SOICN50P130X190X40-5N" land pattern. The device is RoHS-compliant, Pb-free, and MSL Level 1, supporting moisture-insensitive handling and standard lead-free reflow.
