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 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
Features
Y TRI-STATE outputs for data bus applications
Y Buffered inputs minimize loading
Y Address decoding on-chip
Y Diode clamped inputs minimize ringing
Y Available in SOIC (300 mil only)
