Its 7 ns max propagation delay at 5 V and 50 pF load sets the data-rate ceiling in a signal path — if the downstream latch setup time is 3 ns, the path budget leaves 4 ns for the interconnect and clock skew before the hold window closes. Input logic thresholds are fixed at 0.5 V low and 1.5 V high, independent of supply voltage. That means a 1.8 V logic output driving this gate at Vcc=3.3 V will still be recognized as a valid high — the 1.5 V threshold sits below the 1.8 V output high level. The tube delivery means the parts ship in anti-static tubes, not tape-and-reel — factor this into your pick-and-place feeder setup if your line expects tape; the tube format is common for prototyping and low-volume builds. No special bake required before reflow as long as the moisture barrier bag seal is intact — the package is not moisture-sensitive at the MSL level typical for this body size. ROHS3 compliant (lead-free, no exemptions), which clears EU and UKCA regulatory gates for new product introductions. Sourced to order against your BOM quantity through independent distribution.","metaTitle":"SN74LV21APW Texas Instruments AND Gate, 2V-5.5V, 14-TSSOP","metaDescription":"Texas Instruments SN74LV21APW dual 4-input AND gate in 14-TSSOP.
