• RE: SN74LVC1G139: Propagation delay

  

  Chad Crosby

  Hi Daniel, It's difficult to say exactly what the propagation delay for a device will be, however TI guarantees that the delay will fall between that 0.8 & 3.6ns listed on the datasheet, when driving a capacitive load of 15pF. Typically, devices will…
