WebFeb 10, 2024 · The old TTL technology may not have needed default pullup/pulldown resistors, but CMOS logic certainly does. There are two fundamental issues -- First, the … WebFeb 8, 2024 · The pull-up resistor prevents the MCU input from floating when the switch is open; when the switch is closed, the input is pushed down to a logical low. Pull-up resistors are essentially fixed-value resistors linked between the voltage supply (usually +5 V, +3.3 V, or +2.5 V) and the corresponding pin, specifying the input or output voltage in ... Web5 Pull-up or Pull-down Resistors ... when the input is at a TTL level [for ABT V. I = 3.4 V, ΔI. CC = 1.5 mA (see Table 2-1)]. This becomes more critical when the input is in the threshold region as shown in Figure 2-2. These characteristics are typical for all CMOS input circuits, including microprocessors and memories. edge hill university clearing number
