54LS/74LS189 64-BIT RANDOM ACCESS MEMORY (With 3-State Outputs) DESCRIPTION—The ’189 is a high speed 64-bit RAM organized as a 16- word by 4-bit array. Address inputs are buffered to minimize loading and are fully decoded on-chip. The outputs are 3-state and are in the high impedance state whenever the Chip Select (CS) input is HIGH.

Apr 18, 2017 · After waiting months for the 74LS189 without any luck, I decided to use the 6116P integrated circuit instead. You can find the schematic over at http://blog.straypaper.com/2017/12/02/replacing-74ls189-with-6116p/
