Product Overview

The SN74HC259N 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. It is 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. To eliminate the possibility of entering erroneous data in the latches, G\ should be held high (inactive) while the address lines are changing.
  • High-current inverting outputs drive up to 10 LSTTL loads
  • 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
  • 80µA Maximum low power consumption
  • 14ns Typical tpd
  • ±4mA Output drive at 5V
  • 1µA Maximum low input current
  • ±20mA Input and output clamp current
  • ±25mA Continuous output current
  • ±50mA Continuous current through VCC or GND
