MSM534001E

Semiconductor MSM534001E 524,288-Word x 8-Bit MASKROM DESCRIPTION The OKI MSM534001E is a high-speed silicon gate CMOS Mask ROM with 524,288-word x 8-bit capacity. The MSM534001E operates on a single 5.0V power supply and is TTL compatible. The chip's asynchronous I/O requires no external clock assuring easy operation. A power-down mode provides low power dissipation when the chip is not selected. The CE and OE pins are provided as control signals that permit three-stated output allowing easy memory expansion on a system bus. The MSM534001E is suited for use as large capacity fixed memory for microcomputers and data terminals.
