A: As power is turn on the temperature of the IC is at ambient temperature or the initial temperature then becomes the increase in temperature due to heating.
it is three digit seven segment display driver IC
One can find information about an IC system by looking at FAQ specifically about the IC systems which can be found on the IC Systems website and it gives one a wide range of information.
Ep-ic-ness. Three.
Collector emittor and control I believe. The configuration depends on the IC though.
Collector current and emitter current are related by Ic = α Ie with α ≈ 1, so increase in emitter current with temperature is opposed, and operating point is kept stable. Similarly, if the transistor is replaced by another, there may be a change in IC (corresponding to change in β-value, for example). By similar process as above, the change is negated and operating point kept stable

regular with over-current and over-temperature protection.
The 74 indicates a general use IC, the 54 indicates a military specification device with a greater operating temperature range. These two prefixes were originally assigned in the 1960s by Texas Instruments for their TTL logic family, but have since become de facto industry standards. They were also adopted for CMOS in the 1980s when it was decided that having common package pinouts would make it easier for both logic designers and circuit board layout software.
Smart card is generally referred to a card bearing an integrated circuit (IC). Typically, the IC has an operating system of its own and runs an application on it for storing the user data. A terminal with smart card reader is generally used for reading & writing the IC.
