Product details

Overview

NL27WZ00USG-Q from onsemi is a dual 2-input NAND gate IC designed for high-speed logic interfacing in automotive and industrial systems operating from 1.65 V to 5.5 V. It delivers 2.4 ns typical propagation delay at 5 V, supports ±24 mA I/O drive at 3.0 V, and features IOFF partial power-down protection - enabling use in mixed-voltage bus isolation and hot-swap control circuits.

For engineers reviewing the NL27WZ00USG-Q datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, overvoltage-tolerant inputs/outputs up to 5.5 V, US8 package footprint, and guaranteed operation across −55 °C to +125 °C ambient.

Technical Context

The NL27WZ00USG-Q implements two independent CMOS NAND gates with rail-to-rail input voltage tolerance and active-drive output stages capable of sourcing/sinking 24 mA at 3.0 V. Its IOFF circuitry disables I/O leakage when VCC = 0 V, preventing back-driving in partial-power-down configurations.

Propagation delay varies with supply voltage and load: 1.9 ns (typ) at 5 V/15 pF, 2.4 ns (typ) at 3.3 V/15 pF, and 5.7 ns (typ) at 1.8 V/15 pF. Input thresholds scale with VCC (VIH = 0.7×VCC min above 2.3 V), ensuring robust noise margins across the full 1.65–5.5 V range.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC 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 domains without level shifters
tPD (Typ)	2.4 ns at VCC = 5 V, CL = 15 pF - supports >200 MHz toggle rates in low-load digital control paths
I/O Drive	±24 mA at VCC = 3.0 V - sufficient to directly drive LEDs, small MOSFET gates, or multiple 74LVC inputs
Input Tolerance	−0.5 V to +6.5 V - allows safe connection to 5 V signals even when powered from 1.8 V or 2.5 V rails
IOFF Leakage	≤10 µA at VCC = 0 V - prevents signal contention during system power sequencing or standby modes
Operating Temp	−55 °C to +125 °C - qualified for under-hood automotive, industrial motor control, and outdoor embedded applications
AEC-Q100	Qualified per Grade 1 (−40 °C to +125 °C) and extended to −55 °C - meets automotive reliability and stress-test requirements

3 (Y2)	Output of Gate 2	Inverted AND of A2/B2; drives loads up to 24 mA while maintaining rail-aligned VOH/VOL
4 (GND)	Ground Reference	Primary return path for all internal logic and I/O current; must be low-impedance for noise immunity
5 (A2)	Input of Gate 2	First NAND input of second gate; fully decoupled from Gate 1; enables dual independent logic functions
6 (B2)	Input of Gate 2	Second NAND input of second gate; shares same electrical specs as A1/B1
7 (Y1)	Output of Gate 1	Inverted AND of A1/B1; matches Y2 timing and drive strength; supports fanout to multiple downstream loads

Key Features

Feature	Design Value
Wide VCC Range	1.65 V to 5.5 V operation eliminates need for separate voltage translators in multi-rail systems
Overvoltage-Tolerant I/O	Inputs and outputs withstand up to 5.5 V - enables safe interfacing with legacy 5 V peripherals while powered from 1.8 V
IOFF Partial Power-Down	Blocks I/O leakage when VCC = 0 V - critical for hot-swap, battery-backed, or modular subsystem designs
High-Speed Propagation	2.4 ns tPD (5 V) and 3.2 ns tPD (2.5 V) support real-time control loops and fast state-machine transitions
AEC-Q100 Qualified	Grade 1 qualification with PPAP capability - satisfies OEM automotive component release requirements

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC2G00DCKR	Same US8 package, 1.65–5.5 V, but only qualified to −40 °C to +85 °C; no AEC-Q100 certification	Lacks automotive qualification and extended temperature support; suitable for commercial industrial controls only	Select when AEC-Q100 and −55 °C operation are not required; lower cost alternative for non-automotive BOMs
MC74VHC2G00DTT1G	US8 package, −40 °C to +125 °C, but max VCC = 5.5 V and VIH threshold fixed at 2.0 V (not VCC-scaled); IOFF not supported	No IOFF protection limits use in partial-power-down systems; fixed VIH reduces noise margin below 3 V	Choose only if existing design uses VHC family timing models and IOFF is unnecessary; verify VIH compatibility at lowest VCC

Compared with SN74LVC2G00DCKR and MC74VHC2G00DTT1G, the NL27WZ00USG-Q uniquely combines AEC-Q100 Grade 1 qualification, −55 °C operation, IOFF, and VCC-scaled input thresholds - making it the sole option for automotive body electronics requiring guaranteed partial-power-down behavior and wide-temperature reliability.

FAQ

What is the maximum operating temperature range for the NL27WZ00USG-Q?

The NL27WZ00USG-Q is rated for operation from −55 °C to +125 °C ambient temperature, fully qualified per AEC-Q100 Grade 1 with extended low-temperature validation. This specification is confirmed in the Recommended Operating Conditions table (page 3 of the datasheet) and applies across the full 1.65–5.5 V VCC range. The device maintains specified timing and drive performance throughout this range.

Does the NL27WZ00USG-Q support partial power-down protection?

Yes, the NL27WZ00USG-Q includes IOFF circuitry that actively disables input and output leakage paths when VCC = 0 V. Per the datasheet (page 1, Features section and page 4, DC Electrical Characteristics), IOFF leakage is limited to ≤10 µA under power-down conditions - preventing back-driving of live buses and enabling safe hot-swap and modular subsystem designs.

Is the NL27WZ00USG-Q pin-compatible with standard US8 dual NAND gates like the SN74LVC2G00?

The NL27WZ00USG-Q uses the standard US8 pinout (A1, B1, Y2, GND, A2, B2, Y1, VCC), matching SN74LVC2G00DCKR and MC74VHC2G00DTT1G. However, pin compatibility alone does not guarantee functional drop-in replacement due to differences in IOFF support, input threshold scaling, and temperature qualification - verified via direct comparison of pin assignment diagrams and DC/AC specs in respective datasheets.

What is the typical propagation delay of the NL27WZ00USG-Q at 3.3 V supply?

At VCC = 3.3 V and CL = 15 pF, the NL27WZ00USG-Q exhibits a typical propagation delay (tPLH/tPHL) of 2.4 ns, as specified in the AC Electrical Characteristics table (page 4). This value is measured under standard test conditions (RL = 1 MΩ, R1 = open) and remains consistent across both gates (Y1 and Y2) within device-matching tolerances.

Can the NL27WZ00USG-Q safely interface with 5 V logic signals while powered from a 1.8 V supply?

Yes - the NL27WZ00USG-Q inputs are overvoltage tolerant up to 5.5 V regardless of VCC level, as stated in the Features list (page 1) and Maximum Ratings table (page 3). When powered from 1.8 V, it correctly interprets 5 V TTL/CMOS inputs and produces valid 1.8 V logic-level outputs, eliminating external level shifters in mixed-voltage systems.
