LS7211N规格书详情
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).
FEATURES:
• 8-bit programmable delay from microseconds to days
• On chip oscillator (RC or Crystal) or external clock time base
• Selectable prescaler for real time delay generation based on 50Hz/60Hz time base or 32,768Hz watch crystal
• Four operating modes
• Reset input for delay abort
• Low quiescent and operating current
• Direct relay drive
• +3V to +18V operation (VDD - VSS)
• LS7211N, LS7212N (DIP); LS7211N-S, LS7212N-S(SOIC) - See Figure 1-
