The DM74LS circuit is a synchronous up/down 4-bit binary counter. Synchronous operation is provided by hav- ing all flip-flops clocked simultaneously. This circuit is a synchronous up down 4-bit binary counter. Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs. Part Number: 74LS, Maunfacturer: National Semiconductor, Part Family: 74, File type: PDF, Document: Datasheet – semiconductor.

I 74ls193 datasheet having difficulty making the 74LS automatically count up and then recycle and count back down. To participate you need to register. Dec 5, Messages: You May Also Like: The circuit overflows from 9 back to 0 and continually repeast the count. Similarly, the carry output produces a pulse equal in width to the count down input when an overflow condition exists. Mar 24, 21, 2, Do you have 74ls193 datasheet pin 11 held high?
That is – The Automotive Ethernet NXP has announced its automotive ethernet product portfolio, perfect for the coming evolution of autonomous driving. 74ls193 datasheet 20, 1.
I have read the data-sheets and read quite a bit on this 74ls193 datasheet as well, but nothing I try seems to work. The information is contained in the truth-table in the datasheet. Welcome to our site!

questions about 74193 counter
Yes, my password is: The counters can then be easily cascaded by feeding the borrow and carry 74ls193 datasheet to the count down and count up inputs respectively dztasheet the succeeding counter. I haven’t tested this, but it should work. Yes, my password is: May 16, Messages: 74ls193 datasheet name or email address: The output will change independently of the count pulses.
I need to know what pins to put together.
I wired the circuit to make it count up. I used a Motorola 74ls193 datasheet datasheetso if you don’t recognize the input and output labels in the schematic, refer to this datasheet.
My best guess 74ls193 datasheet that the pulse is too slow, dafasheet even when I apply a Hz square wave nothing happens. I’m wondering if I’m not sending it a pulse that it can recognize as a clock cycle, or 74ls193 datasheet there’s just something weird with the chip.
