Operating Supply Voltage

The voltage level by which an electrical system is designated and to which certain operating characteristics of the system are related.

5V

Polarity

Inverting

Power Supplies

an electronic circuit that converts the voltage of an alternating current (AC) into a direct current (DC) voltage.?

5V

Operating Supply Current

12mA

Load Capacitance

the amount of capacitance measured or computed across the crystal terminals on the PCB. Frequency Tolerance. Frequency tolerance refers to the allowable deviation from nominal, in parts per million (PPM), at a specific temperature, usually +25°C.

50pF

Nominal Supply Current

Nominal current is the same as the rated current. It is the current drawn by the motor while delivering rated mechanical output at its shaft.

12mA

Number of Bits

8

Propagation Delay

the flight time of packets over the transmission link and is limited by the speed of light.

20 ns

Turn On Delay Time

Turn-on delay, td(on), is the time taken to charge the input capacitance of the device before drain current conduction can start.

5 ns

Response Time

the time taken for a circuit or measuring device, when subjected to a change in input signal, to change its state by a specified fraction of its total response to that change.

3 ns

Output Function

An output function is a function that an optimization function calls at each iteration of its algorithm. Typically, you use an output function to generate graphical output, record the history of the data the algorithm generates, or halt the algorithm based on the data at the current iteration.
