It performs the logical NOR function — output is high only when all inputs are low — and is used in combinatorial logic, glue logic, and signal conditioning circuits across industrial control, test equipment, and legacy digital systems. ## Lifecycle and compliance It is RoHS non-compliant, so designs requiring RoHS exemption or lead-free assembly must verify compatibility before specifying this device. ## Package and handling No moisture-sensitive level is stated, but standard ESD handling precautions apply for CMOS-input devices.","metaTitle":"5402DMQB NOR Gate, TTL/H/L Series, Active","metaDescription":"5402DMQB is a NOR gate from the TTL/H/L series, currently in active production.
