74F219
64-Bit Random Access Memory with 3-STATE Outputs
General Description
The 74F219 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. This device is similar to the
74F189 but features non-inverting, rather than inverting,
data outputs.
