Answer / anandkumar m k

Not every IC's start with 74, we have 7805,7905, etc. In
case of IC 74 series, we can see that the pin 4 and 7 are
supplied -Vcc and +Vcc supplied respectively. And most
importantly this convention is not the case in every IC
that first two number denotes the power supply pins.

Answer / peddapalli saikumar

some ics r there wich starts with 78 and 79 series.
eg: in 7805 the 78 is a symbol for +ve voltage and 05 is a indiction of voltage quantity,
in 7905 the 79 indicates the -ve coffecient and 05 represent the voltage level...
in the case of 74 series, the voltage level is applied in between these 2 pins.
