HG62E15 Datasheet PDF - Hitachi -> Renesas Electronics

The HG62E series is a master slice CMOS gate array of which the gate length is 1um and user 2-layer metal interconnect technology.

This series has twelve master chips with high gate count/pads from 770/68 to 24,000/272.

These chips can replace not only CMOS logics but also TTL logics due to the high speed of 0.7 ns typ and compatibility of input and output buffers at TTL/CMOS level.
