64-Bit Random Access Memory with TRI-STATE
Outputs
General Description
The ’F219 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
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 This device is similar to the ’F189
but features non-inverting rather than inverting data out-
puts
