Each of its two independent circuits accepts four inputs and delivers a NAND output, making it a direct logic building block for combinatorial gating, address decoding, or enable/disable functions in 2V to 6V systems. The through-hole 14-DIP package suits prototyping, breadboard work, and legacy board revisions where a hand-solderable footprint is preferred over surface-mount alternatives. ## Supply range and speed Rated for a 2V to 6V supply. Propagation delay is 19ns at 6V and 50pF load. Quiescent current maxes at 2 µA. No automotive or military qualification is listed, so this is a commercial/industrial-grade device, not intended for under-hood or avionics deployment without additional screening.","metaTitle":"SN74HC20N 74HC Dual 4-Input NAND Gate, 14-DIP, Active","metaDescription":"SN74HC20N is a dual 4-input NAND gate from the 74HC series. 2V to 6V supply, 19ns propagation delay, -40°C to 85°C.
