74F189 64-Bit Random Access Memory with 3-STATE Outputs
April 1988
Revised July 1999
74F189
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 mini-
mize loading and are fully decoded on-chip. The outputs
are 3-STATE and are in the high impedance state when-
ever 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.
