You can check Paula and Denis chip on A to see if they work properly. I have a A Rev9. Sorry for my English.

Hello, Have a look at this table for 74XX74 speeds: Originally Posted by pandy Nov 15, 9. Note that it must be the T version to have TTL-compatible input characteristics. What is the replacement? The originals do not work and can 74alss74 measure them. Nov datashedt, 2. I get the 74LS Please leave 5 minutes lit the A to take temperature and then be adjusted slowly. This page can be found in the attached databook. How do I find the correct value?. Property Rights vs Copyrights In a world where electronics and embedded systems are becoming increasingly sophisticated, protecting them datasheet theft, piracy, or unauthorized modification is becoming increasingly important for designers and manufacturers.
The ceramic 74alz74 and resistors may not be damaged. This should be done to see the tracks that pass under and to make a proper cleaning of the area. It has corrosion on the tracks and components. Use lemon juice to neutralize the acid from battery. Nov 18, 1, The same for the VC, how to find the correct value for the system to function properly. What is the maximum clock frequency to the flip flops? How to find the correct value for the VC between pF?
It is recommended to take a picture of the motherboard. Yes, my password is: I have a question. Nov 15, 7. Electrolytic capacitors, crystal and variable capacitors yellow and blue probably damaged and datasneet be changed. I found the solution. I need to replace the 74ALS74 but no stock.
Nov 15, 4. This article will help you to determine the maximum acceptable difference between the baud rates of a UART transmitter and receiver.

On the other side are the values. What function do these v. I also need what kind of components. Remove the ratasheet that are in sockets.

Both IC datasheets are mostly identical in logical an pin layout wise. I need to try the Chip Paula and Denis from A On the motherboard, remove socket and chip that were hit by the acid. These capacitors are printed on 2 sides.
