Features:

• LS7211N, LS7212N backwards compatible to LS7211, LS7212
• Generates delays from 100ns to days
• Time base is external clock or oscillator: RC (LS7211N); Crystal (LS7212N)
• 8 binary-weighted delay bits
• 3 selectable prescalers
• Four operating modes
• Reset for delay abort
• 3V to 18V operation
• Programmable frequency division
• Real time delays from 50/60 Hz (LS7211N); watch crystal (LS7212N)

Description:

The LS7211N and LS7212N are CMOS integrated circuits for generating digitally programmable delays. The delay is controlled by 8 binary weighted inputs, WB0 – WB7, in conjunction with an applied clock or oscillator frequency. The programmed time delay manifests itself in the Delay Output (OUT) as a function of the Operating Mode selected by the Mode Select inputs A and B: One-Shot, Delayed Operate, Delayed Release or Dual Delay. The time delay is initiated by a transition of the Trigger Input (TRIG).
