Description
The device is an 8-bit addressable latch with a single data input (D), three address inputs (A0, A1, A2), and a common enable input (E). When the enable input is low, the data on the data input is loaded into the addressed latch on the next high-to-low transition of the clock input. This allows for data storage and retrieval based on the address selected, providing versatile applications in memory and logic operations.
The MC74VHCT259ADR2G operates with a supply voltage range of 2.0V to 5.5V, making it suitable for a wide range of digital applications. Its high-speed performance and low power characteristics make it ideal for use in high-density, cost-sensitive applications.
