Product details
Overview
74LVC1G02QSE-7 from Diodes Incorporated is an automotive-grade single 2-input positive NOR gate in SOT353 package, operating from 1.65V to 5.5V supply, delivering ±24mA output drive at 3.3V, with 5.5V-tolerant inputs and IOFF partial power-down protection-used for voltage level shifting and signal isolation in automotive body control modules.
For engineers reviewing the 74LVC1G02QSE-7 datasheet, 74LVC1G02QSE-7 pinout, 74LVC1G02QSE-7 application, or 74LVC1G02QSE-7 equivalent, key selection criteria include Grade 1 temperature range (–40°C to +125°C), AEC-Q100 qualification, IOFF-enabled power-down safety, and mixed-voltage interface capability in space-constrained automotive logic designs.
Technical Context
This NOR gate implements the Boolean function Y = A + B (positive-logic OR followed by inversion) with push-pull CMOS output stage. Its IOFF circuit actively disables outputs during VCC = 0V, preventing back-current flow in partial-power-down systems.
Input tolerance up to 5.5V enables interoperability across 1.8V/2.5V/3.3V/5V domains without external level shifters. Propagation delay is 2.1ns typical (3.3V, 25°C), with input capacitance of 5.0pF and power dissipation capacitance of 14pF at 10MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |

|---|---|---|
| A | Data Input | First NOR input; 5.5V-tolerant, compatible with higher-voltage logic signals |
| B | Data Input | Second NOR input; identical electrical characteristics to Pin A |
| GND | Ground Reference | Return path for all internal logic and output currents; must be low-impedance for noise immunity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single 2-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G02DBVR | Non-automotive grade; rated –40°C to +125°C but not AEC-Q100 qualified; same SOT23-5 package | Lacks PPAP support and IATF 16949 traceability; unsuitable for safety-critical automotive programs | Select only for industrial or consumer designs where automotive qualification is unnecessary |
| 74LVC1G02GW,125 | NXP variant in SC-70 (SOT323); identical electrical specs but different thermal resistance (θJA = 338°C/W) | SC-70 offers slightly larger pad area than SOT353 but requires re-layout; same AEC-Q100 Grade 1 rating | Choose when existing PCB design uses SC-70 footprints or requires marginally better thermal performance |
Compared with SN74LVC1G02DBVR and 74LVC1G02GW,125, the 74LVC1G02QSE-7 uniquely combines AEC-Q100 Grade 1 qualification, SOT353's smallest footprint among qualified variants, and full IOFF implementation-making it optimal for space-constrained, safety-compliant automotive logic nodes.

FAQ
Is the 74LVC1G02QSE-7 pin-compatible with standard 74LVC1G02 packages?
Yes-it shares identical pinout (A, B, GND, Y, VCC) with industry-standard SOT353-packaged 74LVC1G02 devices, including Diodes' own 74LVC1G02SE-7 and NXP's 74LVC1G02GW. Mechanical dimensions and solder pad layout match JEDEC MO-178AB specifications, enabling drop-in replacement in validated designs.
What is the maximum clock frequency supported by this NOR gate?
The 74LVC1G02QSE-7 does not operate as a clocked device but as combinational logic. Its 2.1ns typical propagation delay (3.3V, 25°C) supports signal toggling up to approximately 100MHz in non-critical timing paths; actual usable frequency depends on system-level setup/hold margins and load capacitance.
Can this device be used for level translation between 1.8V and 5V domains?
Yes-its 5.5V-tolerant inputs allow connection to 5V logic while powered from 1.8V, and its push-pull output swings rail-to-rail, enabling bidirectional level translation when configured with appropriate pull-up/pull-down networks. No external resistors are needed for input-side translation.
Does the IOFF feature require external control signals?
No-IOFF is fully automatic and internally controlled. When VCC drops to 0V, the output enters high-impedance state without any enable/disable pin or external biasing. This behavior is intrinsic to the silicon design and requires no additional circuitry or firmware intervention.
