74F189
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 3-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 plement of the stored data.
Features s 3-STATE outputs for data bus applications s Buffered inputs minimize loading s Address decoding on-chip s Diode clamped inputs minimize ringing
