This depends on the IC. Visual inspection will only go so far. You will need to test it and compare the testing to the datasheet; if it is not testing as specified in the datasheet, then it is bad.
Sorry, there's no one easy answer for all IC's.
u check it
To check the IC by the multimeter, you have to make sure that the pointer points at the current. You can then connect the multimeter across the check the IC.
check your answer
There is no Calculus function like ic 4808. Kindly check your question again.
Check the datasheet for pinout.
ic voltage regulator is good for line or load regulation
The letters "IC" pronounced properly can say "icy" meaning very cold.
Is it APR 9600 or ARP 9600? If it is APR 9600 sound record/replay IC, check out the link given below. It contains the pin configuration of the IC.
To test a good integrated circuit (IC), you can use a multimeter to check for proper voltage levels and continuity between pins, or employ an oscilloscope to verify signal integrity and waveform shapes. For a bad IC, you may observe incorrect voltage readings, lack of expected signals, or excessive heat during operation. Additionally, using specialized testing equipment, such as a logic analyzer, can help identify functional failures by analyzing the IC's output in real-time. If the IC fails these checks, it is likely defective.
As I check there is no summon outstanding maybe not blacklisted yet....
This Easy to build PIC based IC tester is very easy to make and highly reliable.This IC tester can successfully check the most of the IC's we are using in our normal project constructions such as TTL,74,74F,CMOS 4000 series.This could be very useful for the professionals as well as hobbyist.
