Product details

Timing budget and supply flexibility

The SN74LV02APWT is a quad 2-input NOR gate from TI's 74LV series, specified with a 7.5 ns maximum propagation delay at 5V and 50 pF load. That propagation delay is the key number for timing closure in mixed-voltage logic paths — it tells you how much margin remains after the gate's own delay. Supply voltage spans 2V to 5.5V, so the same part can sit on a 3.3V bus and still interface with a 5V peripheral without a separate level translator.

Output drive and fan-out

Each output sources or sinks 12 mA at the rated supply — enough to drive a few CMOS gate inputs or a low-speed optocoupler, but not a relay coil or LED directly. The 20 µA quiescent current keeps the static power draw negligible in battery-powered designs.

Package and temperature grade

The 0.65 mm pin pitch is fine enough that a 2-layer board can route it, but a 4-layer board gives cleaner supply routing for the 7.5 ns edge rates.

Frequently asked questions

What is the closest functional second-source to SN74LV02APWT?

The SN74LV00APWR is the NAND-gate sibling in the same 74LV series, same package and supply range. For a NOR gate, the SN74LV02APWT itself is the direct part; no pin-compatible NOR alternative is listed in the same series.

Is SN74LV02APWT equivalent to 74HC02?

Both are quad 2-input NOR gates, but the 74LV series operates from 2V to 5.5V with lower quiescent current (20 µA max) versus the 74HC series which typically runs 2V to 6V and draws higher static current. The 74LV02 is a lower-power drop-in for 5V systems.
