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 outp
