Quad NOR gate for mixed-voltage digital buses
The SN74LV02APWR is a quad 2-input NOR gate from TI's 74LV series, operating across a 2V to 5.5V supply range. Propagation delay is 7.5ns typical at 5V with a 50pF load, fast enough for bus arbitration and control signals in 20-40 MHz digital systems. The 12mA symmetrical output drive can sink or source enough current to drive multiple CMOS inputs or a single TTL load on the same net.
Housed in a 14-TSSOP package with 0.173-inch body width (4.40mm), the SN74LV02APWR fits the standard 14-pin TSSOP footprint shared by most 74LV logic gates. Surface-mount assembly with the tape-and-reel option suits volume pick-and-place.
For a BOM that already uses the 74LV00APWR (quad NAND) or 74LV08ADR (quad AND), the SN74LV02APWR shares the same supply voltage, output drive, and package — only the logic function changes.
