The CA3046 (P/N 156-0048-00) is a transistor array monolithic integrated circuit (aka LM3046). 156-0068-00 is the same part selected to VCEsat ≤0.4 V.
The CA3086 (PN 156-0197-00) / LM3086 is identical but has no guaranteed Vos/Ios specs.
Other possible alternatives include the NTE912.
The IC contains five 15 V, 50 mA, 120 MHz Si-NPN transistors. One pair has a common emitter pin.
