Si!l0otiCS 82S25 64-BIT BIPOLAR SCRATCH PAD MEMORY (16x4 RAM) FEBRUARY 1975 DIGITAL 8000 SERIES TTL/MEMORY DESCRIPTION The 82S25 is a 64-bit, Schottky clamped TTL, ReadWrite Random Access Memory ideal for use in scratch pad and high-speed buffer memory applications. The 82S25 is a fu lIy decoded memory array organ ized as 16 words of 4 bits each, with separate input and output lines. It Features PNP inputs, one chip enable line, and open collector outputs for ease of memory expansion. The outputs of the 82S25 assume a logic "1" state during write. This allows both memory inputs and outputs to share a mon bus for minimizing interconnections, and more effective utilization of mon I/O...
