Description

The SN74HC11N is a Triple 3-Input AND Gate IC manufactured by Texas Instruments, housed in a standard 14-pin DIP through-hole package. This device contains three independent 3-input AND gates, with each gate performing the Boolean function Y = A ● B ● C in positive logic — meaning each of the three sections outputs HIGH only when all three of its inputs are HIGH.

Built on high-speed CMOS (HC) logic technology, this chip offers buffered inputs, a wide operating voltage range of 2V to 6V, and a wide operating temperature range of -40°C to +85°C, while supporting fanout up to 10 LSTTL loads — making it flexible enough to interface cleanly with both modern low-voltage logic and legacy TTL-based systems. It delivers fast average propagation delay of around 7ns with strong 24mA drive strength, giving reliable, low-power AND logic performance for demanding digital designs.

With three independent AND gates on a single chip, the SN74HC11N is a compact, efficient building block for combinational logic design — commonly used for multi-input enable conditions, address decoding logic, control circuits, and general Boolean AND functions in digital systems.
