PLUS405-55 Datasheet (NXP) - Programmable logic sequencer

PLUS405-55, Programmable logic sequencer

The PLUS405-55 device is a bipolar, programmable state machine of the Mealy type.

Both the AND and the OR array are user-programmable.

All 64 AND gates are connected to the 16 external dedicated inputs (I0 - I15) and to the feedback paths of the 8 on-chip State Registers (QP0 - QP7).
