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.
