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 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
