Quiescent current is 2 µA maximum, keeping the static power draw negligible in battery-backed or always-on logic sections. Output drive capability is 4 mA source and 4 mA sink, sufficient for driving standard CMOS inputs or a single TTL load per output. ## Lifecycle and compliance ROHS3 compliant, so it fits lead-free assembly processes without exemption paperwork.","metaTitle":"SN74HCT02N NOR Gate, 14-DIP, 4.5V-5.5V, Active","metaDescription":"Texas Instruments SN74HCT02N quad 2-input NOR gate in 14-DIP.
