Part Manufacturer: Motorola


Part Description: 74LS170

Part Details:

SN54/74LS170 4 x 4 REGISTER FILEOPEN-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, bothaddress and enable, allow simultaneous read and write operation. 4 x 4 REGISTER FILE Open-collector outputs make it possible to connect up to 128 outputs in a OPEN-COLLECTOR wired-AND configuration to increase the word capacity up to 512 words. Any LOW POWER SCHOTTKY number of these devices can be operated in parallel to generate an n-bitlength. The SN54 / 74LS670 provides a similar function to this device but it features 3-state outputs.· Simultaneous Read/Write Operation · Expandable to 512 Words of n-Bits J SUFFIX · Typical Access Time of 20 ns CERAMIC · Low Leakage Open-Collector Outputs for Expansion CASE 620-09 · 16 Typical Power Dissipation of 125 mW 1 N SUFFIX CONNECTION DIAGRAM DIP (TOP VIEW) PLASTIC CASE 648-08 16 VCC D1 WA WB EW E Q R 1 Q2 1 16 15 14 13 12 11 10 9 NOTE:The Flatpak version D SUFFIX has the same pinouts SOIC 16 (Connection Diagram) as CASE 751B-03 1 the Dual In-Line Package.
