Additional Details:
The SN74LS259N operates from a single 5V power supply. Each latch can be individually addressed using a 3-bit address input. Data is latched when the enable input is high and the selected address matches the input address. The device includes an asynchronous clear input that resets all latches to a low state when asserted. It is housed in a 16-pin DIP package. It is part of the 74LS series of logic gates using TTL technology.
