Input pin logic levels and threshold voltages.
Negative going noise on the input voltage will not cause a false transition back to a logic 0 unless it is greater than 0. Pre-coded C-language routines make it easy to access these features. NI equips engineers and scientists with systems that accelerate productivity, innovation, and discovery. Through our standard NI technical support program, we can help you:. The hysteretic input works together with any source impedance driving the pin to provide some immunity against noise and to debounce the input signal.
The maximum current you should ever source from the pin is 25 ma. The trigger voltage can lie anywhere within the 1.
Digital I/O – Hardware Interfacing
They consist of internal diodes that conduct current from the input pin to the supply or ground rails in the event that the input pin voltage exceeds the supply range. Device Overview and Block Diagram. If there is the possibility of the output pin being driven to a negative voltage level it is better to prevent excessive power dissipation in the processor package by externally clamping the voltage to ground V SS with a Schottky diode.
The Module Mapping Control Guide shows you how to use the control registers for the HCS12 Microcontroller and how to configure the device’s memory map.
We calculate it as. Consult on how to dayasheet NI products Overcome development challenges Quickly resolve issues pre- or post-deployment To access NI technical support services for your hardware, visit ni.
The consequence of this hysteresis is that the threshold between a logic high and a logic low depends on whether the input voltage is rising or falling.

From the LED datasheet we note that its forward voltage at a current of 10 mA is specified to be 2. The maximum current you should ever sink with the pin is 25 ma. Hccs12 following graphs show that in reduced drive mode the resistance of an output pin is approximately ohms in either the high or low state.
That is, for currents of less than 10 mA the voltage change is linear with current; it can be modeled as a voltage source of either zero or five volts and an equivalent series resistance of 40 ohms 1.

See All Countries and Regions. When the input voltage rises from a logic 0 toward a logic 1 level, the logic 1 is dataheet when the voltage rises to 2. For some applications, particularly when driving inductive loads such as relays, you may need to provide Schottky diode clamps between the pin and V DD and between the pin and ground.
