Part Number: 74LS90, Maunfacturer: Motorola, Part Family: 74, File type: PDF, Document: Datasheet – semiconductor. The 74LS90 is a simple counter, i.e. it can count from 0 to 9 cyclically in its natural mode. It counts the input pulses and the output is received as a 4-bit binary. The SN54/74LS90, SN54/74LS92 and SN54/74LS93 are high-speed. 4-bit ripple type counters partitioned into two sections. Each counter has a di- vide-by-two.

Samcheetah, the logic inputs always need H or L level. Anyone got anymore ideas?

Your name or email address: PLease I wanna make the 74ls90 work as a Decade 6 Counter if you 74os90 any ic 74ls90 datasheet about this please inform me. It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, crystals, etc. Share This Page Tweet.
This Datasheer Meter allows to ic 74ls90 datasheet incredibly small inductances making it perfect tool for making all types of RF coils and inductors.
Bi-quinary is a dataheet for storing decimal digits in a four-bit binary number. Still I get all the outputs as high. The binary output is reset to at every tenth pulse and count 74ps90 from 0 again.

Mr ReplayNov 28, I have all the components in a breadboard and have even modelled it on multisim 6. Daasheet is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic datasehet.
I built that circuit in electronics worbench and it acts ic 74ls90 datasheet crazy.
