Triple 3-input AND gate for mixed-voltage glue logic
The Texas Instruments SN74LV11AD is a triple 3-input AND gate from the 74LV low-voltage CMOS family. It packs three independent AND gates, each with three inputs, into a single 14-SOIC package. The supply range spans 2V to 5.5V, with input logic thresholds at 0.5V (low) and 1.5V (high), making it a natural fit for boards that mix 3.3V and 5V logic domains — no level shifter needed between a 3.3V MCU and a 5V peripheral bus.
7.9 ns propagation delay — timing budget for 50–100 MHz buses
Maximum propagation delay is 7.9 ns at 5V with a 50 pF load. That is fast enough for address decoding or clock gating in systems running up to roughly 50–100 MHz, where the gate delay eats a small fraction of the cycle. At 3.3V the delay stretches a bit (typical datasheet curve), so budget an extra nanosecond or two if the rail is on the low side.
Industrial temperature range and quiescent current
Rated for -40°C to 85°C, the SN74LV11AD suits outdoor telecom cabinets, factory-floor PLCs, and engine-bay electronics that see thermal cycling. Quiescent current maxes at 20 µA across the full temperature range — negligible for battery-backed or always-on domains. Output drive is 12 mA sink and source, enough for a few CMOS loads or a short trace.
Active lifecycle — no LTB pressure
TI lists the SN74LV11AD as Active with ROHS3 compliance. No end-of-life notice, no last-time-buy clock ticking. This is a standard-production part you can qualify into a new BOM or sustain on an existing one without worrying about a forced redesign next year.
