MN54F189-X REV 1A0
64-BIT RANDOM ACCESS MEMORY WITH 3-STATE OUTPUTS
General Description
The F189 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.
and are in the high impedance state whenever the Chip Select (CS) input is HIGH.
outputs are active only in the Read mode and the output data is the complement of the
stored data.
