Microchip Technology's 27HC291 series offers a 16Kb UV Erasable Programmable Read-Only Memory (UVPROM) with a 2K x 8 organization. The 27HC291-55-SJ features a maximum access time of 55ns, enabling efficient data retrieval in applications requiring rapid read operations. This CMOS component operates asynchronously and is housed in a 24-pin Ceramic Dual In-line Package (CDIP), suitable for through-hole mounting. Its 3-state output characteristics and common I/O provide design flexibility. The device supports a supply voltage range of 4.5V to 5.5V, with a nominal voltage of 5V. Typical applications include industrial control systems, legacy equipment, and specialized embedded systems where reliable, non-volatile data storage is critical. The 27HC291 series is designed for robust performance in demanding environments.
