The Microchip Technology 27HC291 is a 16Kbit (2K x 8) One-Time Programmable (OTP) Read-Only Memory (ROM) device. It operates from a single 4.5V to 5.5V supply and offers a fast access time of 55ns, facilitating high-speed data retrieval. Manufactured using advanced CMOS technology, this component features asynchronous operation and 3-state outputs for flexible system integration. The 27HC291 series is commonly employed in applications requiring non-volatile code storage and fixed data sets, such as industrial control, embedded systems, and legacy equipment. This specific part, the 27HC291-55I-SP, is housed in a 24-pin Plastic Dual In-line Package (PDIP) with through-hole mounting. Its operational temperature range is -40°C to +85°C, ensuring reliable performance in demanding environments.
