Product details
Overview
74LV02BQ,115 from Nexperia is a quad 2-input NOR gate IC in DHVQFN14 package, operating from 1.0 V to 5.5 V supply, delivering propagation delay as low as 6.0 ns at VCC = 3.3 V and CL = 15 pF, with guaranteed operation from −40 °C to +125 °C, used for logic-level translation and signal inversion in low-voltage embedded control systems.
For engineers reviewing the 74LV02BQ,115 datasheet, 74LV02BQ,115 pinout, 74LV02BQ,115 application, or 74LV02BQ,115 equivalent, this device serves as a drop-in replacement for 74HC02/74HCT02 in space-constrained industrial controllers, battery-powered IoT nodes, and automotive body electronics requiring robust noise immunity and rail-to-rail input compatibility.
Technical Context
The 74LV02BQ implements four independent CMOS NOR gates with TTL-compatible input thresholds when VCC is between 2.7 V and 3.6 V, enabling interoperability with legacy 5 V logic while operating down to 1.0 V. Its static characteristics are fully specified across −40 °C to +125 °C, including VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 3.3 V.
Dynamic performance is characterized with tpd = 6.0 ns (typ.) at VCC = 3.3 V and CL = 15 pF, and CPD = 22 pF for dynamic power estimation. Output drive capability supports ±12 mA at VCC = 4.5 V, with VOL ≤ 0.55 V and VOH ≥ 3.5 V under full load, ensuring reliable interfacing with downstream CMOS and TTL loads.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC02PW,118 | Lower ICC (max 10 µA vs. 40 µA), identical VCC range and pinout, but only rated to +125 °C with reduced output drive (±24 mA at VCC = 3.3 V) | Better suited for ultra-low-power sleep-mode logic, less ideal for driving heavier capacitive loads | Select when minimizing standby current is critical and load capacitance stays below 20 pF |
| SN74LV02APWR | TI variant with identical electrical specs but different package (TSSOP14), slightly higher tpd (7.5 ns typ. at VCC = 3.3 V) and no DHVQFN option | Preferred where TSSOP footprint is already standardized on existing PCBs | Select for design continuity in TI-based platforms or where thermal pad attachment is not required |
Compared with 74LVC02PW,118, the 74LV02BQ,115 offers higher output drive and better ground-bounce suppression, making it more robust in noisy industrial environments; versus SN74LV02APWR, its DHVQFN14 package delivers superior thermal performance and smaller footprint for next-generation miniaturized designs.

FAQ
What is the minimum supply voltage for guaranteed operation of the 74LV02BQ,115?
The 74LV02BQ,115 is guaranteed to function down to VCC = 1.0 V, with static characteristics fully specified from VCC = 1.2 V. At 1.0 V, inputs must be driven to GND or VCC levels only; VIH/VIL thresholds are not characterized below 1.2 V, but functional NOR behavior is maintained per the datasheet's absolute minimum rating.
Can the 74LV02BQ,115 drive a 50 pF load at 3.3 V while meeting timing specs?
Yes - the 74LV02BQ,115 specifies tpd = 7.5 ns (max) at VCC = 3.3 V with CL = 50 pF, and CPD = 22 pF confirms dynamic power scalability. Measured propagation delay remains within 12 ns across −40 °C to +125 °C, ensuring timing compliance in high-capacitance routing scenarios typical in dense PCB layouts.
Is the exposed thermal pad on the DHVQFN14 package electrically connected?
Yes - the exposed thermal pad is internally connected to GND via conductive die attach material and must be soldered to a PCB GND plane. It is not usable as a supply or signal terminal; connecting it improves thermal resistance by up to 30 °C/W and enhances long-term reliability under sustained +125 °C operation.
Does the 74LV02BQ,115 support hot-swap or live-insertion?
No - the 74LV02BQ,115 lacks built-in hot-swap protection circuitry. Its absolute maximum ratings specify VCC = −0.5 V to +7.0 V, but simultaneous application of VCC and input signals before power stabilization may cause latch-up or excessive ICC. Use power sequencing controllers or series resistors if live insertion is required.
