CD54HCT299 - 8-Bit Universal Shift Register

Download the CD54HCT299 datasheet PDF. This datasheet also covers the CD54HC299 variant, as both devices belong to the same 8-bit universal shift register family and are provided as variant models within a single manufacturer datasheet.

Description

The ’HC259 and ’HCT299 are 8-bit shift/storage registers with three-state bus interface capability.

The register has four synchronous-operating modes controlled by the two select inputs as shown in the mode select (S0, S1) table.

Features

  • Buffered Inputs.
  • Four Operating Modes: Shift Left, Shift Right, Load and Store.
  • Can be Cascaded for N-Bit Word Lengths.
  • I/O0 - I/O7 Bus Drive Capability and Three-State for Bus Oriented.
