A standard TTL input at logic "1" is normally operated assuming a source current of 40 μA, and a voltage level above 2.4 V, allowing a pull-up resistor of no more than 50 kohms; whereas the TTL input at logic "0" will be expected to sink 1.6 mA at a voltage below 0.8 V, requiring a pull-down resistor less than 500 ohms.

Pull-up resistors are provided by the I3C controller. External pull-up resistors are no longer needed. Clock Stretching – devices are expected to be fast enough to operate at bus speed. The I3C controller is the sole clock source. I²C Extended (10-bit) Addresses. All devices on an I3C bus are addressed by a 7-bit address.
The purpose is to reduce the overall power demand compared to using both a strong pull-up and a strong pull-down. [10] A pure open-drain driver, by comparison, has no pull-up strength except for leakage current: all the pull-up action is on the external termination resistor.
The output pull-up resistor is built into some encoders; if not built in, an external resistor is required. Open collector drivers (using an NPN transistor or open drain drivers using an n-type MOSFET ) allow operation over a wide range of signal voltages and often can sink significant output current, making them useful for directly driving ...

The voltage drop across any resistor depends on the current flowing; in a circuit, currents can change and consequently the voltages at specific points in that circuit may go up at one end of what is called a pull-up resistor, or down at one end of what is called a pull-down resistor. 70.27.152.243 19:57, 20 July 2016 (UTC)
