DS8863/DS8963 MOS-to-LED 8-Digit Driver General Description Features The DS8863 and DS8963 are designed to be used in conjunction with MOS integrated circuits and common-cathode LED’s in serially addressed multi-digit displays. The DS8863 is an 8-digit driver. Each driver is capable of sinking up to 500 mA. The DS8963 is identical to the DS8863 except it is intended for operation at up to 18V.
