GENERAL DESCRIPTION
The K3N7V(U)4000C-DC is a fully static mask programmable ROM organized 4,194,304x16 bit. It is fabricated using silicongate CMOS process technology. This device operates with a low power supply, and all inputs and outputs are TTL compatible. Because of its asynchronous operation, it requires no external clock assuring extremely easy operation. It is suitable for use in program memory of microprocessor, and data memory, character generator. The K3N7V(U)4000C-DC is packaged in a 42-DIP.
