Описание

The SN74HC259D is a 8-bit Addressable Latch 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. Four distinct modes of operation are selectable by controlling the clear (CLR) and enable (G) inputs. In the addressable-latch mode, data at the data-in terminal is written into the addressed latch. The addressed latch follows the data input, with all unaddressed latches remaining in their previous states. In the memory mode, all latches remain in their previous states and are unaffected by the data or address inputs.

• Wide operating voltage range
• Outputs can drive up to 10 LSTTL loads
• Low power consumption
• 14ns Typical TPD
• ±4mA Output drive at 5V
• 1µA Maximum low input current
• Asynchronous parallel clear
• Active-high decoder
• Enable input simplifies expansion
• Green product and no Sb/Br
