54F 74F189 64-Bit Random Access Memory with TRI-STATE Outputs August 1995 54F 74F189 64-Bit Random Access Memory with TRI-STATE Outputs General Description The ’F189 is a high-speed 64-bit RAM organized as a 16word by 4-bit array Address inputs are buffered to minimize loading and are fully decoded on-chip The outputs are TRISTATE 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 Features Y Y Y Y Y TRI-STATE outputs for data bus applications Buffered inputs minimize loading Address decoding on-chip Diode clamped inputs minimize ringing Available in SOIC (300 mil only) Commercial 74F189PC Military Package Number N16E Package Description 16-Lead (0 300
