●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 outputs are active only in the Read mode and the output data is the complement of the stored data.

●Features

●■3-STATE outputs for data bus applications

●■Buffered inputs minimize loading

●■Address decoding on-chip

●■Diode clamped inputs minimize ringing
