74F670 - 4 x 4 register file

Description

The 74F670 is a 16-bit 3-State Register File organized as 4 words of 4 bits each.

Separate Read and Write Address and Enable inputs are available, permitting simultaneous writing into one word location and reading from another location.

The 4-bit word to be stored is presented to four data inputs.

Features

  • Simultaneous and Independent Read and Write operations.
  • Expandable to almost any word size and bit length.
  • 3-State outputs.
