Technical content

The TTL /MSI SN54 /74LS670 is a high-speed, low-power 4 x 4 Register File organized as four words by four bits. Separate read and write inputs, both address and enable, allow simultaneous read and write operation. The 3-state outputs make it possible to connect up to 128 outputs to in- crease the word capacity up to 512 words. Any number of these devices can be operated in parallel to generate an n-bit length. The SN54/74LS170 provides a similar function to this device but it features open-collector outputs.

  • Simultaneous Read/Write Operation
  • Expandable to 512 Words by n-Bits
  • Typical Access Time to 20 ns
  • 3-State Outputs for Expansion
  • Typical Power Dissipation of 125 mW CONNECTION DIAGRAM DIP (TOP VIEW) NOTE: The Flatpak version has the same pinouts (Connection Diagram) as the Dual In-Line Package. /C0049/C0052/C0049/C0051 /C0049/C0050 /C0049/C0049 /C0049/C0048 /C0057 /C0049 /C0050 /C0051 /C0052 /C0053 /C0054/C0055 /C0049/C0054 /C0049/C0053 /C0056 /C0086/C0067/C0067 /C0068/C0050 /C0068/C0049/C0087/C0065/C0087/C0066/C0069/C0087 /C0081/C0049/C0069/C0082 /C0081/C0050 /C0068/C0051/C0068/C0052/C0082/C0066/C0082/C0065/C0081/C0052/C0081/C0051/C0071/C0078/C0068 PIN NAMES LOADING (Note a) HIGH LOW NOTES: a) 1 TTL Unit Load (U.L.) = 40 µA HIGH/1.6 mA LOW.
