Part Number Status
DS1123L Active: In Production. See Ordering Information for details.


The DS1123L is an 8-bit programmable timing element similar in function to the DS1023, but operating at 3.3V. Like the DS1023, the DS1123L can delay signals up to a full period or more when used as a delay line, and an on-chip reference delay can be used to offset the inherent "step-zero" delay. This allows the DS1123L to shift a clock signal over the full 0 to 360° phase range. In addition to functioning as a delay line, it can be configured as a free-running oscillator or an externally triggered monostable vibrator.
