Six open-drain inverters — the pull-up is your call
The SN74LVC06AD from Texas Instruments packs six independent inverter gates with open-drain outputs into a single 14-SOIC package. Unlike a standard push-pull gate, each output can only sink current — it pulls low actively but relies on an external pull-up resistor to return high. That makes it the natural choice for wired-OR bus structures, level translation between voltage domains, and driving loads like LEDs or relay coils where you control the pull-up voltage independent of the logic supply.
1.65 V to 3.6 V — wide-range supply for mixed-voltage boards
Supply range spans 1.65 V to 3.6 V, covering 1.8 V, 2.5 V, and 3.3 V logic families. The input logic thresholds scale with the rail: low-level at 0.7 V to 0.8 V, high-level at 1.7 V to 2 V. That means it can accept 1.8 V logic signals cleanly when running from a 3.3 V supply, or interface 3.3 V outputs to a 1.8 V core — the open-drain output and external pull-up do the level shifting for you.
3.5 ns propagation delay — fast enough for 100 MHz buses
Maximum propagation delay is 3.5 ns at 3.3 V with a 50 pF load. That keeps timing closure straightforward for clocked logic up to about 100 MHz, with enough margin that signal-integrity budget is rarely the bottleneck. Quiescent current maxes at 1 µA, so the power penalty for leaving unused gates biased is negligible.
-40 to 125 °C — industrial temperature grade
Rated for -40 to 125 °C operating temperature, this part is at home in motor drives, outdoor telecom cabinets, factory automation panels, and under-hood automotive auxiliary circuits. The 14-SOIC package reflows cleanly with standard profiles and the body is small enough for dense layouts.
Active lifecycle — no LTB pressure
The SN74LVC06AD carries an active product status with ROHS3 compliance. No last-time-buy notice, no end-of-life clock ticking.
