TLC555-Q1: Propagation delay from detecting at TRIG and THRES pins to output

Part Number: TLC555-Q1

Hi all,

I would like to know what is the tPHL and tPLH in the TLC555-Q1 datasheet Figure 8. Those times are not found in the datasheet. Do you have approx parameter of this propagation delay to detect from H to L and L to H? Also, I would like to know the propagation delay from detecting crossing the 2/3Vdd (1/3Vdd) to output.

 

Regards,
RYO

  • RYO,

    These values are built into the TLC555 Component Calculator. The calculator will chose resistors values for a given capacitor and output frequency and duty cycle.
