General Description

The IlPB406 and IlPB426 are high-speed, electrically programmable, fully-decoded 4096-bit TTL read-only memories.

On-chip address decoding, two chip·enable inputs and open-collector/three-state outputs allow easy expansion of memory capacity.

The IlPB406 and IlPB426 are fabricated with logic level zero (low);
