Product details

Overview

NLV18SZ07DFT2G from onsemi is an automotive-grade single CMOS open-drain buffer logic gate in SC-88A (SOT-353) package, operating from 1.65 V to 5.5 V, with 3.7 ns typical propagation delay at 3.0 V and ±24 mA output drive capability, used for level-shifting and wired-OR bus interfacing in vehicle body control modules.

For engineers reviewing the NLV18SZ07DFT2G datasheet, pinout, applications, or equivalent options, key selection criteria include open-drain output architecture, AEC-Q100 Grade 1 qualification (−40°C to +125°C), SC-88A footprint compatibility, and 5.5 V absolute maximum supply rating.

Technical Context

The NLV18SZ07DFT2G implements a single-channel open-drain buffer with active-high input and high-impedance output in tri-state mode when input is low. It features symmetrical output impedance and balanced tPLH/tPHL propagation delays under defined load conditions (RL = 1 MΩ, CL = 15 pF).

Its DC electrical behavior includes input threshold voltages (VT+ = 1.9 V, VT− = 0.6 V at VCC = 3.0 V), hysteresis of 1.2 V, and guaranteed VOL ≤ 0.28 V at IOL = 12 mA - enabling robust noise immunity and reliable pull-up interface design in mixed-voltage automotive subsystems.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	1.65 V to 5.5 V - supports direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains
tPD (Typ)	3.7 ns at VCC = 3.0 V, RL = 1 MΩ, CL = 15 pF - enables high-speed signal buffering in CAN/LIN peripheral interfaces
IOL (Max)	24 mA at VCC = 3.0 V - drives standard 4.7 kΩ pull-up resistors on 3.3 V buses without voltage droop
Operating Temp	−40°C to +125°C (AEC-Q100 Grade 1) - qualified for under-hood and cabin control unit deployment
Input Hysteresis	1.2 V at VCC = 3.0 V - suppresses false triggering from EMI-induced input noise in automotive harness environments
ESD Rating	2000 V HBM - meets ISO 10605 requirements for electrostatic discharge robustness in assembly and field operation
Package	SC-88A (SOT-353), 5-pin - 2.2 mm × 1.35 mm footprint compatible with space-constrained PCB layouts

Pinout & Package

SC-88A (Case 419A-02) is a 5-pin surface-mount package with gull-wing leads, 0.65 mm pitch, and exposed pad not present. Pin 1 is marked by a dot or beveled corner per tape-and-reel orientation diagram.

Pin/Terminal	Circuit Role	Design Meaning
1	N.C.	No internal connection - must remain unconnected; floating or tied to GND/VC_C has no functional impact
2	A	Active-high digital input - logic high enables output pull-down; logic low places Y in high-impedance state
3	GND	Ground reference - shared return path for input/output current and internal biasing networks
4	Y	Open-drain output - sinks current when A = HIGH; presents Hi-Z when A = LOW; requires external pull-up
5	V_CC	Positive supply - powers internal logic and output stage; decoupling capacitor (100 nF) recommended near pin

Key Features

Feature	Design Value
Open-drain output architecture	Enables wired-OR bus configurations and level translation between disparate voltage domains without direction control logic
AEC-Q100 Grade 1 qualification	Validated for continuous operation from −40°C to +125°C ambient, meeting automotive electronics reliability and lifetime requirements
High noise immunity	Input hysteresis ≥1.2 V and VIH/VIL margins >30% of VCC ensure stable switching in electrically noisy engine bay environments
Low quiescent current	ICC ≤ 1 µA max at TA = 25°C - minimizes standby power in always-on vehicle modules such as door lock controllers
Pb-free, RoHS-compliant packaging	Meets EU Directive 2011/65/EU and automotive ELV requirements; compatible with lead-free reflow soldering profiles (peak 260°C)

Equivalent & Alternatives

The following parts are listed as comparable options for similar open-drain buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MC74VHC1G07DTT1G	Non-automotive grade; rated −40°C to +85°C only; identical SC-88A pinout and open-drain function	Lacks AEC-Q100 qualification and extended temperature support - unsuitable for under-hood use	Select only for non-automotive industrial or consumer designs where cost sensitivity outweighs qualification needs
SN74LVC1G07DBVR	Industrial grade (−40°C to +125°C), but not AEC-Q100 qualified; same 5-pin SC-70 package, slightly higher ICC (10 µA)	Acceptable for cabin modules with controlled thermal environment, but not PPAP-capable for Tier 1 OEM sourcing	Prefer when existing board layout uses SC-70 and qualification documentation is not required by customer

Compared with NLV18SZ07DFT2G, MC74VHC1G07DTT1G offers identical functionality at lower cost but lacks automotive qualification, while SN74LVC1G07DBVR provides extended temperature range without formal AEC-Q100 validation - making NLV18SZ07DFT2G the sole choice for production-critical, PPAP-mandated vehicle systems.

FAQ

What is the absolute maximum supply voltage for NLV18SZ07DFT2G?

The absolute maximum DC supply voltage (VCC) for NLV18SZ07DFT2G is +6.5 V, as specified in Table 1 Maximum Ratings. Operation above this voltage risks permanent damage. For reliable long-term performance, the device must be operated within the recommended range of 1.65 V to 5.5 V per Table 2. NLV18SZ07DFT2G is not rated for 6 V system rails unless transient clamping is implemented externally.

Does NLV18SZ07DFT2G have a defined output high voltage (VOH)?

No - NLV18SZ07DFT2G does not specify VOH because it features an open-drain output. The output voltage in the high state is determined solely by the external pull-up resistor and its connected supply rail. Per Note 5 in the datasheet, VOH is not applicable to open-drain devices like NLV18SZ07DFT2G, NLV18SZ06DFT2G, and others in the series.

Can NLV18SZ07DFT2G drive a 4.7 kΩ pull-up resistor on a 5 V bus?

Yes - NLV18SZ07DFT2G can reliably drive a 4.7 kΩ pull-up on a 5 V bus. At VCC = 5.5 V and IOL = 12 mA, VOL is guaranteed ≤ 0.4 V (Table 3), yielding a worst-case output low voltage of 0.4 V - well within TTL and CMOS logic thresholds. This ensures clean signal integrity for wired-OR bus topologies in NLV18SZ07DFT2G-based designs.

Is NLV18SZ07DFT2G pin-compatible with other SC-88A logic buffers?

Yes - NLV18SZ07DFT2G shares the identical SC-88A (SOT-353) 5-pin pinout with other NLV18SZxx variants including NLV18SZ04DFT2G (inverter) and NLV18SZ16DFT2G (buffer). Pin 1 is N.C., Pin 2 is input, Pin 3 is GND, Pin 4 is output, and Pin 5 is VCC - enabling drop-in substitution within the same function group when redesigning for different logic types.

What is the thermal resistance (θJA) of NLV18SZ07DFT2G in typical PCB layout?

The junction-to-ambient thermal resistance (θJA) of NLV18SZ07DFT2G is 659°C/W, measured on an FR4 board with minimum pad spacing, using a 10 mm × 1 inch, 20 oz copper trace and no airflow (Note 2, Table 1). This value assumes standard JEDEC test conditions; actual θJA will improve with enhanced copper pour and thermal vias in production PCBs hosting NLV18SZ07DFT2G.
