Maxim DS1123L Datasheet
The DS1123L is an 8‑bit programmable timing element that can delay signals up to a full period or more, providing phase adjustment over a 360° range. It can be programmed via an 8‑bit parallel interface or a 3‑wire serial interface, and can also operate as a monostable vibrator or an adjustable frequency oscillator.
The device operates from a single 3.3 V supply and is offered in four step‑size variants (0.25 ns to 2 ns). Electrical specifications include a supply voltage of +3.0 V to +3.6 V, input logic thresholds, and current ratings. Pin‑out details, timing diagrams, and application notes are provided for proper integration.
