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.

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.

Bi-quinary is a system 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. Electro Tech is an online community with overmembers who enjoy ic 74ls90 datasheet about and building electronic circuits, projects and gadgets.

Daasheet is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. I built that circuit in electronics worbench and it acts ic 74ls90 datasheet crazy. If you are interested the project is at: Supply voltage; 5V 4.
