[I.MX93] eMMC design : pull-up & pull-down resistor オプション 解決済み ソリューションへジャンプ 01-28-2025 03:36 AM 561件の閲覧回数 Chou Contributor II Dear NXP Community, I am currently working on the eMMC PCBA design for the I.MX93 and noti...
instead of pulling a pin to a high value, such resistors pull the pin to a low valued instead. Though being less commonly used, a pull-down resistor is still a valid option.
A TTL input is actually the emitter of a multiple emitter transistor. It wants to source current into some kind of load. The amount of current is a "standard TTL load" of 1.6 mA. The biggest pulldown resistor you could use would be 0.8V/1.6 mA or 500 ohms. A smaller resistor...
I assume that the external pull-up/down resistors used for the evaluation board work, but by reading the datasheet it seems that if the internal pull-down resistor approaches its lower limit indicated in the datasheet, then the voltage level on high logic state during the boot could be ...
Pull-up and pull-down resistors– These resistors are used to set a specific level (logic 0 or logic 1) at a floating pin. A pull-up resistor is connected to the power supply so it can pull the floating pin to logic high level. A pull-down resistor connects the floating pin to the...
My customer design wrong schematic. it input 3.3V for PDB even VDDIO=1.8 but they have serial resistor on PDB signal line as below. So I think they can use this serial resistor to change PDB level to 1.8V if I know Pull down resistor in PDB IO. ...
Pull-down Resistor Schematic Just like the pull-up resistor in the first figure, the pull-down resistors in this circuit also ensures that the voltage between VCC and a microcontroller pin is actively controlled when the switch is open. Unlike the pull-up resistor, the pull-down resistor pull...
use TXS0102 for the tx rx pins of the BG95M3 GPS&GSM integrated circuit. In the datasheet of TXS0102, it tells me to pull down the OE pin, but in the datasheet of BG95M3, it says that I need to add pull down and pull up resistors. Should I add an extra pull ...
The first figure of schematic presents a relatively low input resistance and thus imposes a low value on external pulldown resistor to provide the desired low-level input voltage. In figure two, an active-pulldown circuit substitutes a saturated transistor for a power-consuming pulldown resistor....
For simplicity, we will focus on pull-ups since they are more common than pull-downs. They operate using the same concepts, except the pull-up resistor is connected to the high voltage (this is usually 3.3V or 5V and is often refereed to as VCC) and the pull-down resistor is connected...
