82S12 Datasheet (Signetics) - HIGH SPEED MULTIPORT MEMORY

82S12, HIGH SPEED MULTIPORT MEMORY

The 82S12/112 is a Schottky TTL 32 bit multiport memory organized in 8 words of 4 bits each.

The device is ideally suited for high speed accumulators and buffer memories.

Stored data is addressed through 2 independent sets of 3-input decoders, and read out when the corresponding output enable line i
