156-0048-00

The CA3046  (P/N 156-0048-00) is a transistor array (aka LM3046). 156-0068-00 is the same part selected to V_CEsat ≤0.4 V.

The CA3086 / LM3086 is identical but has no guaranteed V_os/I_os 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.
