SN74LVC1G123: Output pulse duration

Datta Prasad Thiyagarajan

Part Number: SN74LVC1G123

We are using SN74LVC1G123 in one our legacy designs which I am trying to understand. Rext value used is 100k. Cext value is 47 uF. I am not able to calculate the output pulse duration from the datasheet. Can you pleae help to calculate the output pulse duration with these Rext and Cext values.

Best Regards

Hi Datta,

Please see this thread for a more thorough explanation: (+) SN74LVC1G123: Output Pulse duration - Logic forum - Logic - TI E2E support forums

You would need to test for the K value yourself since your capacitance is so large. But I'd guess something like t_w = KRC = 0.8 x 100k x 47u ~ 3.79s.

Best,

Malcolm
