Product details
Overview
NLSF308MNR2 from onsemi is a quad 2-input AND gate IC fabricated in advanced high-speed CMOS technology, delivering 4.3 ns typical propagation delay at 5.0 V while maintaining low power dissipation (2.0 µA max ICC). It operates across 2.0–5.5 V supply range, supports mixed-voltage interfacing (inputs tolerate up to 7.0 V), and is housed in a 3×3 mm QFN-16 package with exposed thermal pad. It serves as a logic-level combinatorial gate in digital control, interface translation, and signal conditioning circuits.
For engineers reviewing the NLSF308MNR2 datasheet, pinout, applications, or equivalent options, key selection criteria include propagation delay vs. supply voltage, input overvoltage tolerance, noise immunity (28% VCC), output drive capability (±25 mA), and QFN-16 thermal performance in space-constrained PCB layouts.
Technical Context
The NLSF308MNR2 implements four independent 2-input AND gates in a single monolithic silicon-gate CMOS die, with three-stage internal buffering to ensure stable output transitions and high noise immunity. Its inputs are 7.0 V tolerant, enabling direct interfacing between 3.0 V and 5.0 V logic domains without level shifters.
It features balanced tPLH/tPHL propagation delays, power-down protection on all inputs, and latchup immunity exceeding 300 mA. The device meets ESD requirements per Human Body Model (>2000 V) and Machine Model (>200 V), and is rated for operation from −40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay (tPD) | 4.3 ns typ @ VCC = 5.0 V, CL = 15 pF - enables sub-200 MHz combinational logic timing in high-speed digital systems. |
| Supply Voltage Range | 2.0 V to 5.5 V - supports dual-rail operation and compatibility with legacy 5 V and modern low-voltage 3.3 V/2.5 V systems. |
| Input Voltage Tolerance | −0.5 V to 7.0 V - allows safe connection to higher-voltage signals without external clamping diodes. |
| Output Drive Current | ±25 mA per pin - sufficient to directly drive multiple standard TTL or CMOS loads without buffer amplification. |
| Noise Immunity | VNIH = VNIL = 28% VCC - ensures robust operation in electrically noisy industrial or automotive environments. |
| Quiescent Supply Current | 2.0 µA max @ TA = 25°C - enables ultra-low static power in battery-backed or always-on logic monitoring circuits. |
| Operating Temperature | −40°C to +85°C - qualified for extended industrial temperature applications including motor control and PLC I/O modules. |
Pinout & Package
Package: QFN-16 (3 mm × 3 mm, 0.5 mm pitch, exposed thermal pad, case 485G). RoHS-compliant, Pb-free option available (NLSF308MNR2G).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 12 | A1–A4 (Inputs) | First input of each AND gate; 7.0 V tolerant, compatible with mixed-voltage signaling. |
| 2, 4, 9, 13 | B1–B4 (Inputs) | Second input of each AND gate; identical electrical characteristics to A pins. |
| 5, 7, 10, 16 | Y1–Y4 (Outputs) | AND logic outputs; rail-to-rail swing, ±25 mA sink/source capability. |
| 6 | GND | Ground reference for all logic and power domains; connected to exposed thermal pad for improved thermal dissipation. |
| 15 | VCC | Primary power supply (2.0–5.5 V); decoupling capacitor required within 3 mm for stable high-speed operation. |
| 11, 14 | NC | No-connect terminals; must remain unconnected per design - no internal circuitry attached. |
Key Features
| Feature | Design Value |
|---|---|
| High-Speed CMOS Architecture | 4.3 ns tPD at 5 V matches bipolar TTL speed while consuming <2 µA static current - ideal for power-sensitive high-throughput logic. |
| Mixed-Voltage Interface Support | 7.0 V-tolerant inputs enable direct 5 V → 3.3 V domain bridging without external level translators - reduces BOM count and layout area. |
| Enhanced Noise Immunity | 28% VCC noise margin ensures reliable operation under >200 mV peak noise - critical for industrial sensor interface and motor driver control logic. |
| Power-Down Input Protection | Inputs remain high-impedance and non-latching during VCC ramp-up/down - prevents false triggering during power sequencing in multi-rail systems. |
| Latchup Immunity | Exceeds 300 mA per JEDEC JESD78 - guarantees robustness against transient current injection in harsh EMI environments. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC08APWR | Higher ICC (10 µA typ), 1.65–5.5 V range, no 7 V input tolerance, SOIC-14 package (larger footprint). | Requires external level shifters for 5 V → 3.3 V interfacing; unsuitable for direct mixed-voltage node connection. | Select when board space permits SOIC and cost is prioritized over input overvoltage robustness. |
| 74AUP1G08GW,125 | Single-gate SOT-353 package, 0.8–3.6 V only, 3.8 ns tPD, 0.9 µA ICC - no multi-gate integration. | Requires four separate placements and routing for same functionality; increases layout complexity and test points. | Select only for ultra-low-power single-channel use cases where quad integration is unnecessary. |
Compared with SN74LVC08APWR and 74AUP1G08GW,125, the NLSF308MNR2 uniquely combines 7.0 V input tolerance, quad integration in 3×3 mm QFN, and sub-5 ns delay at 2 µA quiescent current - making it optimal for compact, mixed-voltage, industrial-grade logic consolidation.

FAQ
What is the maximum input voltage rating for NLSF308MNR2?
The NLSF308MNR2 supports DC input voltages from −0.5 V to +7.0 V, independent of VCC. This allows safe interfacing between higher-voltage domains (e.g., 5.0 V microcontrollers) and lower-voltage logic (e.g., 3.3 V FPGAs) without external protection components. This specification is confirmed in the Maximum Ratings table of the official NLSF308 datasheet Rev. 5.
Does NLSF308MNR2 support operation at 2.5 V supply?
Yes, NLSF308MNR2 is fully specified for operation from 2.0 V to 5.5 V, including 2.5 V. At VCC = 2.5 V, it maintains guaranteed VOH ≥ 2.0 V and VOL ≤ 0.1 V under 4 mA load, with propagation delay increasing to ~10.5 ns (max) per AC Electrical Characteristics. This makes NLSF308MNR2 suitable for mixed-supply systems using 2.5 V I/O standards.
Is the exposed thermal pad on the QFN-16 package of NLSF308MNR2 required to be soldered?
Yes, the exposed thermal pad (Pin 6/GND) on the NLSF308MNR2 QFN-16 package must be soldered to a PCB thermal pad connected to the system ground plane. Per onsemi's packaging guidelines (Case 485G), this connection is essential for achieving rated thermal performance and reliability. Omitting the thermal pad connection risks exceeding junction temperature limits under sustained 25 mA output loading.
Can NLSF308MNR2 replace older 74HC08 logic in existing designs?
NLSF308MNR2 is functionally compatible with 74HC08 but offers superior specs: 4.3 ns tPD vs. ~15 ns for HC, 2.0 µA ICC vs. ~2 µA (typ) but with tighter max spec, and 7.0 V input tolerance vs. VCC+0.5 V for HC. Pinout differs (QFN-16 vs. SOIC-14), so PCB redesign is required - however, the NLSF308MNR2 provides measurable improvements in speed, power, and interface flexibility over legacy HC devices.
What is the meaning of "MN" suffix in NLSF308MNR2?
The "MN" suffix in NLSF308MNR2 denotes the QFN-16 package variant (Case 485G) with standard lead finish and tape-and-reel packaging (3000 units per reel). It distinguishes this version from other offerings like NLSF308MNR2G (Pb-free variant) and confirms mechanical and electrical equivalence to the base NLSF308 device as defined in the ON Semiconductor ordering information table.
