74F219A Datasheet (Philips) - 64-bit TTL bipolar RAM

74F219A, 64-bit TTL bipolar RAM

The 74F219A 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 in high impedance state whenever the chip enable (CE) is high.

The outputs are active only in the READ
