SN74LS170 Datasheet 4 X 4 Register File Open-collector

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

Overview: 4 x 4 REGISTER FILE OPEN-COLLECTOR The TTL / MSI SN54 / 74LS170 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. Open-collector outputs make it possible to connect up to 128 outputs in a wired-AND configuration 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.

This datasheet includes multiple variants, all published together in a single manufacturer document.

Key Features

  • 3-state outputs.
  • Simultaneous Read/ Write Operation.
  • Expandable to 512 Words of n-Bits.
  • Typical Access Time of 20 ns.
  • Low Leakage Open-Collector Outputs for Expansion.
  • Typical Power Dissipation of 125 mW.
