64-Bit Random Access Memory with 3-STATE Outputs
74F189 64-Bit Random Access Memory with 3-STATE Outputs April 1988 Revised June 2002 74F189 64-Bit Random Access Memory with 3-STATE Outputs General Description Features The F189 is a high-speed 64-bit RAM organized as a 16-3-STATE outputs for data bus applications word by 4-bit array. Address inputs are buffered to mini-Buffered inputs minimize loading mize loading and are fully decoded on-chip. The outputs Address decoding on-chip are 3-STATE and are in the high impedance state when- Diode clamped inputs minimize ringing 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.
