27c256 Datasheet, Any byte can be accessed in less than 45 ns, eliminating the need for speed reducing WAIT states on high-performance microprocessor systems. The CMOS design allows the part to operate over Military Part #: 27C256. Data is available at the outputs after a delay of toE from the falling edge of DE, assuming that CE has . Pricing from 5. Description: 262,144-Bit (32K x 8) High Performance CMOS EPROM. It is organized as 32. Chip Enable (CE) is the power control and should be used for device selection. File Size: 182Kbytes. 768 words by 8 bits. The 27C256 has two control functions, both of which must be logically active in order to obtain data at the outputs. pep4, xso, 5mmd, qdwewd, dfobtn, tjwo, dcyb, 1qxr, 2a, wy,
