Is 74LS a CMOS?
74 series families They are CMOS ICs with the same pin arrangements as the older 74LS family. Note that 74HC inputs cannot be reliably driven by 74LS outputs because the voltage ranges used for logic 0 are not quite compatible, use 74HCT instead.
What is the difference between 74LS and 74HC?
difference between 74ls 74hc The 74LS is Transistor to Transistor logic. Uses Shottky transistors to reduce the stored charge and get higher switching speeds then with conventional bipolar transistors. The 74HC uses MOSFET technology. Therefore can operate with wider variety of voltages.

What is fan in and fan-out?
Fan-in refers to the maximum number of input signals that feed the input equations of a logic cell. Fan-out refers to the maximum number of output signals that are fed by the output equations of a logic cell.
Which logic family has maximum fan-out?
CMOS
CMOS has the highest fan-out among the given logic families.
How many fans are in a parallel fan?
Two fans in parallel. (Click on the image for an enlarged view.) In most instances fans in parallel will be in some form of plenum application. Unlike fans in series when typically only two fans are involved, parallel fan applications may use multiple fans.
What is the maximum current a 6 volt fan can output?
If there is no need to drive any inputs the maximum current is about 5mA with a 6V supply, or 10mA with a 9V supply (just enough to light an LED). To switch larger currents you can connect a transistor. Fan-out: one output can drive up to 50 inputs.
How many Ma can a logic-0 fan out?
Similarly, (d) shows that the output stage can — when in the logic-0 state — absorb up to 16 mA before its output voltage falls below 0.4 V; it is thus capable of driving up to 10 Standard inputs, and is said to have a logic-0 fan-out (= IOL/IIL) of 10.
How many fans are placed in series to reduce pressure?
When this occurs, two fans are placed in series with each taking about one-half of the pressure. Two fans in series. (Click on the image for an enlarged view.)
