SN54HC259J - 8-Bit Addressable Latches

Download the SN54HC259J datasheet PDF. This datasheet also covers the SN54HC259 variant, as both devices belong to the same 8-bit addressable latches family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.
  • Expan.
