The DS1003 is an all‑silicon 4‑tap delay line designed for RISC microprocessors and coprocessors. It delivers four delayed clock phases, preserves input symmetry, and offers TTL/CMOS‑compatible inputs and outputs. The device is supplied in 8‑pin and 14‑pin DIP packages and can drive up to four LS‑TTL or CMOS loads per tap.
Typical applications include timing generation for RISC systems, where precise phase relationships are required. The datasheet details electrical characteristics, absolute maximum ratings, pin assignments, test setup, and mechanical dimensions, allowing designers to integrate the part into their circuits with confidence.
