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. The outputs are 3-state
and are in the high impedance state whenever the Chip Select (CS) input is HIGH. The
outputs are active only in the Read mode and the output data is the complement of the
stored data.
