BULLETIN NO. LNXC-D REVISED 2/89 ARI RED LION CONTROLS. With a pull-up resistor, the input pin will read a high state when the button is not pressed. In other words, a small amount of current is flowing between VCC and the input pin (not to ground), thus the input pin reads close to VCC. When the button is pressed, it connects the input pin directly to ground. The current flows through the resistor to ground, thus the input pin reads a low state, MRc y e t s 0 —ni 0 n —1 u m m I h c t i l G MR to Reset Propagation Delay tMD —0.5 a pull-down resistor must be connected from RESET to ground to discharge stray capacitances and hold the output low (Figure 2-2).

The terms “pull up” and “pull down” resistors confused the heck out of me but I get it now. A resistor limits current. In the water analogy, current is the speed of the flow of water. But I never knew what a pull up/pull down resistor was. Until a few weeks ago when I started building a set of buttons for a project I’m working on… Essentially a button is a switch, when the switch 6/04/2007 · Pull Up/Pull Down resistors are placed into circuits for the purpose of setting a high or low, rather than letting the pin float. Sometimes, a chip will not operate if a pin is floating because there is not a definitive voltage value. No defined voltage value means the chip receives no logic. Some pins can be left floating; depends on the data sheets.

The first thing to recognize when dealing with an open drain output is whether a pull-upor a pull-down resistor is needed. This depends on whether the IC drives the output high or low when it wants to assert it. For example, the TPS62067 step-downconverter has a PG output that it drives low if the chip’s output voltage is not in regulation. Therefore, PG needs a pull-upresistor that pulls 22 LED_2 Open drain LED driver Alternative function PO[31] 23 PIO_0 Bi-directional with weak pull_down Programmable input/output line 24 PIO_1
