Frequently Asked Questions
What is the SN74ALS259D and what does it do?
The SN74ALS259D is an 8-bit addressable latch IC from Texas Instruments. It combines a 1:8 demultiplexer with D-type latches, allowing a single data input to be selectively stored into one of eight latch outputs based on a 3-bit address. The reset function is active only when the latch enable is high, providing precise control over output states.
What are the key electrical specifications of the SN74ALS259D?
The SN74ALS259D features a maximum output low current (I_OL) of 8 mA, a load capacitance (CL) of 50 pF, and operates within the ALS (Advanced Low-power Schottky) logic family. It comes in a 16-pin SOIC package (R-PDSO-G16) and is JESD-609 e4 RoHS compliant.
What are typical applications for the SN74ALS259D?
The SN74ALS259D is commonly used in microprocessor-based systems for address decoding, data demultiplexing, and bus expansion.
