Description

The 54F189 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 TRISTATE and are in the high impedance state whenever the Chip Select (CS) input is HIGH. The outputs of 54F189 are active only in the Read mode and the output data is the complement of the stored data.
