Additional Details:

The LD27C64-20 requires a single 5V power supply for operation. Its CMOS technology ensures low power consumption, making it suitable for portable and battery-powered devices. The device features TTL-compatible inputs and outputs, simplifying interfacing with other digital circuits. The fast access time of 200ns allows for rapid retrieval of stored data. It is packaged in a standard 28-pin DIP (Dual In-line Package). To erase the stored data, the device must be exposed to UV light of a specific wavelength for a certain duration. The LD27C64-20 is often used in applications where firmware or configuration data needs to be stored persistently. Rochester Electronics ensures that this device meets the original manufacturer's specifications and provides a reliable source for customers requiring this memory chip.
