Frequently asked questions
How can I order the DSC1223CI3-429M5000 or check availability?
Submit an RFQ with your target quantity and lead-time requirement — we confirm pricing and availability per order.
Is the DSC1223CI3-429M5000 compatible with a 3.3V supply?
Yes — the supply voltage range is 2.5V to 3.3V, so it operates directly on a 3.3V rail without an external regulator.
Does the DSC1223CI3-429M5000 have an enable/disable feature?
Yes, the part includes an enable/disable function. When disabled, the typical supply current drops from 32 mA to 23 mA.
