Product details

Single-gate NOR in the 74LVC family

It performs the NOR logic function on two inputs and outputs the result, operating from a supply range of 1.65V to 5.5V.

The 32mA output current specification for both high and low states is unusually strong for a single-gate device — it can drive multiple CMOS inputs or even a low-power LED directly. The 4.5ns propagation delay at 5V with a 50pF load keeps the gate fast enough for most control and data-path applications below 100 MHz.

There is no successor part to track — the DBVT suffix indicates the SOT-23-5 package variant in Tape & Reel, which is the most common ordering format for automated assembly. The ROHS3 compliance is current and covers all EU exemption categories.

Package and footprint consideration

The SOT-23-5 (SC-74A) footprint is a standard small-outline transistor package with 1.27 mm pitch. No exposed pad or thermal via is needed — the 10 µA quiescent current means self-heating is negligible.

Frequently asked questions

What is the difference between SN74LVC1G02DBVT and SN74LVC1G02DBVR?

The DBVT and DBVR suffixes both refer to the SOT-23-5 package variant but differ in the tape-and-reel packaging format. The DBVT is typically supplied in a 7-inch reel with 250 units per reel, while the DBVR is on a 13-inch reel with 3000 units per reel. The electrical specifications, temperature range, and logic function are identical between the two ordering codes.

What are the equivalent parts to SN74LVC1G02DBVT?

The closest functional equivalent is the SN74LVC1G02DBVR, which is electrically identical but packaged in a different reel quantity. For a dual-gate alternative with the same supply range and logic family, the SN74LVC2G08YZPR provides two AND gates in a single package, though the logic function differs (AND vs NOR). The SN74LVC08ADR and SN74LVC08ADBR offer four AND gates in a single package, suitable when multiple gates are needed on the same board.

Is SN74LVC1G02DBVT RoHS compliant?

Yes, the SN74LVC1G02DBVT is ROHS3 compliant, meeting the latest EU RoHS directive requirements. This covers all ten restricted substances including lead, mercury, cadmium, and the four phthalates.
