The 3D7324 Monolithic Quadruple Fixed Delay Line is an integrated circuit that uses all-silicon, low-power CMOS technology. It has features such as TTL/CMOS compatible inputs and outputs, low ground bounce noise, leading- and trailing-edge accuracy, and temperature and Vdd stability. The delay range is from 6ns to 6000ns with a tolerance of 2% or 1.0ns.
The 3D7324 is a four‑channel fixed‑delay line IC built in all‑silicon, low‑power CMOS technology. Each channel provides a programmable delay from 6 ns up to 6000 ns, with TTL/CMOS‑compatible inputs and outputs that can drive ten 74LS‑type loads. The device is offered in 14‑pin DIP and SOIC packages and is RoHS compliant.
Key specifications include a delay tolerance of 2 % or 1 ns, temperature stability of +3 % over –40 °C to 85 °C, and VDD stability of +1 % over 4.75 V to 5.25 V. Absolute maximum ratings allow supply voltages from –0.3 V to 7 V, and the part operates with a static supply current of about 5 mA.
