• SN74LV123A: K-Vcc characteristic

  

  Ryoma Ohashi

  Resolved

  Part Number: SN74LV123A Hi team, In the datasheet, K-Vcc is spec'd only for CT=1000pF, 0.01uF, 0.1uF and 1uF. But my customer wants to use CT=10uF with Vcc=3.3V or 5V. Could you show us the characteristic for CT=10uF? Regards, Ohashi
