SN74LS170, SN74LS170D Datasheet - Motorola

SN74LS170 4 x 4 REGISTER FILE OPEN-COLLECTOR

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. The SN54 / 74LS670 .

SN74LS170 Features
