The 2 mA output-high and 20 mA output-low drive current gives enough fan-out to feed multiple TTL loads without external buffers. ## TTL-compatible thresholds and supply rail Input logic levels are 0.8 V low and 2 V high, making the part directly compatible with standard 5 V TTL logic families. ## Active production with RoHS compliance It is ROHS3 compliant, meeting the current restriction-of-hazardous-substances directive for lead-free assembly.","metaTitle":"SN74AS20N Texas Instruments 74AS NAND Gate, 5ns @ 5V","metaDescription":"SN74AS20N dual 4-input NAND gate in 14-DIP. 5ns propagation delay at 5V, 50pF.
