SN74LS670
4 x 4 Register File
with 3-State Outputs
The TTL / MSI SN74LS670 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
increase the word capacity up to 512 words. Any number of these
devices can be operated in parallel to generate an n-bit length.
• 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
