SN74HC259DT

The Texas Instruments SN74HC259DT is an 8-bit addressable latch, functioning as a versatile component for digital systems. It is designed for general-purpose storage, serial-to-parallel conversion with storage, and can act as a 1-of-8 decoder or demultiplexer with active-high outputs.

This device features a wide operating voltage range from 2V to 6V, making it adaptable to various system requirements. It offers a typical propagation delay of 14 ns and an output drive capability of ±4 mA at 5V. The low power consumption, with a maximum ICC of 80 µA, and low input current of 1 µA make it suitable for power-sensitive applications.

The SN74HC259DT performs serial-to-parallel conversion with storage and includes an asynchronous parallel clear function. Its active-high decoder and enable input simplify system expansion for n-bit applications, offering four distinct functional modes. The component is housed in a 16-SOIC package, suitable for surface mounting.

Key electrical characteristics include a 2V to 6V operating voltage range and a typical propagation delay of 13ns. The output current is rated at 5.2mA, and it operates within a temperature range of -40°C to 85°C. The 1:8 circuit configuration and D-Type, Addressable logic type define its core functionality.
