Timing specification of LMC555

Other Parts Discussed in Thread: LMC555

 

Dear Technical Support Team,

 

I have some questions about LMC555.

 

1.)

"6.5 Electrical Characteristics" shows "t: Timing Accuracy " .

Dose it mean timing interval accuracy like a following figure?

 


 

In addition, Do Δt/ΔVS and Δt/ΔT mean "Timing interval Shift with Supply" and "Timing Interval Shift with Temperature" ?

 


 

2.)

Test condition of " Timing Accuracy " includes "SW 2, 4 Closed" and it is based on following schematic.

Is "SW 2, 4 Closed" correct configuration for " Timing Accuracy " ?

 


 

If SW 1, 4 Closed, this configuration means like a Figure 6. Astable (Variable Duty Cycle Oscillator).

So I think correct test configuration of " Timing Accuracy " is " SW 1, 4 Closed ",

because /trigger can be set frequently with capacitor(charge/discharge).

 

 

Best Regards,

y.i
