Description

The 74F219A is a high speed, 64bit RAM organized as a 16word by 4bit array. Address inputs are buffered to minimize loading and are fully decoded on chip. The outputs are in high impedance state whenever the chip enable (CE) is high. The outputs are active only in the READ mode (WE = high) and the output data of the 74F219A is the complement of the stored data.
