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.
