Microchip Technology 27HC641-40-J is a 64 Kbit (8K x 8) CMOS UV EPROM with a maximum access time of 40ns. This component features asynchronous operation and 3-state outputs, designed for parallel data transfer. The device is housed in a 24-pin, dual in-line ceramic package with a window for UV erasure. Operating from a 4.5V to 5.5V supply, it offers a typical standby current of 40mA and a maximum active current of 141mA. Applications for this memory device span industrial control, data logging, and legacy system support where non-volatile storage and reprogrammability are critical. The 27HC641 series provides reliable data retention and is suitable for environments requiring robust memory solutions.
