Microchip Technology's 27HC641-55I-J is a 64Kbit (8K x 8) CMOS UV erasable programmable read-only memory (UVPROM). This component offers a maximum access time of 55ns and operates asynchronously with common I/O. The 24-pin ceramic dual in-line package (CDIP24) with a window is designed for through-hole mounting. Operating across a temperature range of -40°C to +85°C, it features 3-state outputs and a supply voltage range of 4.5V to 5.5V. Its robust construction and reliable performance make it suitable for applications in industrial control, telecommunications, and legacy system upgrades. The 27HC641 series UVPROM provides a non-volatile storage solution for firmware and data requiring ultraviolet erasure.
