54F74F189 64-Bit Random Access

Memory with TRI-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 TRI-

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
