WebJul 20, 2012 · TTl inverter is quicker than the RTL inverter. It has a fall time of 1.8ns and a rise time of 1.6µs. The reason both RTL and TTL inverters have slow rise time is because after being in saturation it takes time to remove the stored charge from the base and get transistor to the cutoff state. WebSep 26, 2024 · The reason some suggest not to use low Ic/Ib ratios (i.e. they warn you against putting the BJT in deep saturation) is because the deeper the saturation, the larger the stored charge in the base, the longer the turn-off time (like a diode).
