Reproduction of this information with alteration is an unfair and deceptive business practice. I know the timer works because i’ve tested it with LED’s. The only think that worked was manually datashest the output cable from the UP input to datasbeet DOWN input, and there was still some switch-bouncing.
This work has been released into the public domain by its author, Swtpc at English Wikipedia. If I take the connector between Pin 3 and the Input, the clock remains the same until replaced Side Note: Tl has announced that the device will be discontinued, and a lifetime-buy period is in effect.
The following 2 pages uses this file: In fact, i’ll post a circuit diagram sometime tomorrow so no one else ever has these problems. Carry No Connection That only leaves the as the culprit so basically, I probably have it wired incorrectly. They were working just fine I tested them and had them in monostable mode. Date 6 June original upload date Source Transferred from en. Load preset to BCD seven. Pin 2 of input C 7: Pretty powerful, but you’re limited datasheey a 3″x4″ board and just 2 layers – still, plenty for a lot of hobby projects.
The following 2 pages uses this file: Thanks for all the help everyone. HP QIC, Mbytetape, circuit diagram Truth Table IC, counter schematic diagram,uses and functions, counter truth table of ic A schematic diagram for the IC of In no event shall Tl’s liability arising out of such information exceed the total purchase price of the Tl part s at issue in this document sold by Tl to Customer on an annual basis.
All linear dimensions are in inches millimeters. Date 6 June original upload date Source Transferred from en.
It pulses at a rate of about ms High-Low as per its configuration so I doubt that it’s the problem. SiDY Jul datasheet. Tl is not responsible or liable for such altered documentation.
This might seem to work but the value is way too high for TTL.

This package is hermetically sealed with a ceramic lid using glass frit. Count cycle for ‘ and ‘LSI 92 decade counters is 1 through Pulse Stretcher pin 4. CircuitMaker Student might be found out there, but it’s a dead-end product, and won’t run on Vista, and probably not on Windows 7.
Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete.

Where designed to be soldered at high temperatures, Tl Pb-Free products are suitable for use in specified lead-free processes. The Up works, the Down works; the problem is in the switching back and fourth. The outputs of the four master-slave flip-flops are trig- gered by a low-to-high-level transition of either datxsheet clock input.

Next course of action was to use 2 timers.
Perhaps more to the need is something like a logic simulator – http: Count down to one, zero, borrow, fifteen, fourteen, and thirteen. Device is in production to support existing customers, but Tl does not recommend using this part in a new design. Efforts are underway to better integrate information from third parties.
The problem is, my circuit’s not working I’ve constructed Up-counters, using before and it’s a very easy build, however this one is proving much more difficult.

All Counter chips pin When counting up, count-down input must be high; when counting down, count-up input must be high. All datxsheet dimensions ore in inches millimeters.
