SN74HC259D

SN54HC259, SN74HC259 SCLS134F – DECEMBER 1982 – REVISED MARCH 2022 SNx4HC259 8-Bit Addressable Latches 1 Features Wide operating voltage range of 2 V to 6 V High-current inverting outputs drive up to 10 LSTTL loads Low power consumption, 80-μA max ICC Typical tpd = 14 ns ±4-mA output drive at 5 V Low input current of 1 μA max 8-bit parallel-out storage register performs serial- to-parallel conversion with storage Asynchronous parallel clear Active-high decoder Enable input simplifies expansion Expandable for n-bit applications Four distinct functional modes 2 Description These 8-bit addressable latches are designed for general-purpose storage applications in digital systems. Specific uses include working registers, serial-holding registers, and active-high decoders or demultiplexers. They are multifunctional devices capable of storing single-line data in eight addressable latches and being a 1-of-8 decoder or demultiplexer with active-high outputs.
