Triple 3-input AND gate in 14-DIP — 74LS logic
The SN74LS11N is a triple 3-input AND gate from the 74LS low-power Schottky family, in a 14-pin DIP package for through-hole mounting. It integrates three independent AND gates, each with three inputs, on a single chip. Typical applications include general-purpose logic gating in 5V TTL systems — industrial controllers, test equipment, and legacy digital boards where a clean AND function is needed without routing discrete diodes.
20 ns propagation delay — timing margin for 5V buses
Maximum propagation delay is 20 ns at 5V supply with a 15 pF load.
Output drive and quiescent current
Output high current is 400 µA, output low sinks 8 mA — enough to drive one or two standard TTL loads but not a relay coil or LED directly without a buffer. Quiescent supply current maxes at 3.6 mA per package, which is typical for the 74LS family and fine for a 5V rail with modest power budget.
Active lifecycle — no LTB risk
This part carries an Active product status and is ROHS3 compliant. For a BOM freeze, this gate is a safe line item — no imminent obsolescence to trigger a redesign or second-source qualification.
