Intel QD27C256-250 is a 262144-bit UV Erasable Programmable Read-Only Memory organized as 32K words by 8 bits. This CMOS device offers a maximum access time of 250ns, ensuring efficient data retrieval. The QD27C256 series utilizes asynchronous operation and features 3-state outputs for flexible system integration. Housed in a 28-lead Ceramic Dual In-line Package (CDIP28), it is designed for through-hole mounting with a terminal pitch of 2.54mm. Typical applications include industrial control, telecommunications, and embedded systems requiring non-volatile program storage. The component operates with a nominal supply voltage of 5V and a programming voltage of 12.5V, with a maximum supply current of 30mA.
