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 This symbol is also similar to figure 5. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards. Jun 30, 7. I’ve tried both arrangements, but to no avail. The clear function is independent of the count and load Inputs. All following user names refer to en.

Datasheet pdf – SYNCHRONOUS UP/DOWN DECADE(,BINARY) COUNTER – SGS Thomson Microelectronics

The operating modes of the ‘ decade counter and the ‘ binary counter are identical, with the only difference being the count sequences as noted in theclock input signals to the next higher order circuit in a multistage counter. Count cycle for ‘ and ‘LSI 92 decade counters is 1 through This symbol is also similar to figure 5. The original description page was here.

When I turn on the circuit and yes, i’m using a regulated 5V for the enture breadboard the 7-segment display I have shows “0” but does not change. It’s current configuration goes as follows: This page was last edited on 6 Juneat The following 2 pages uses this file: This feature allows the counters to be used as modulo-N dividers by simply modifying the count length with the preset inputs.

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 contact their board assembly site for stencil design recommendations.

Jun 30, 8. Pin 7 of input A 4: The counter may be preset by the asynchronous parallel load capability of the circuit.

That only leaves the as the culprit so basically, I probably have it wired incorrectly. Public domain Public domain false false. Body dimensions do not include mold flash or protrusion, not to exceed 0, Device is in production to datxsheet existing customers, but Tl does not recommend using this part in a new design.

Datashheet Wikimedia Commons, the free media repository. When counting up, count-down input must be high; when counting down, count-up input must be high.

The output will change to agree with the data In- puts independently of the count pulses. By using this site, you agree to the Terms of Use and Privacy Policy. 71492

The counters can then be easily cascaded by feeding the borrow and carry outputs to the count-down and count-up inputs respectively of the succeeding counter.

I’ve heard that before on other threads. This package is hermetically sealed with a ceramic lid using glass frit.


Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete.

Jun 30, 9. Vref is V for ‘ and ‘, 1. Both borrow and carry outputs are available to cascade both the up- and down-counting functions. Datasbeet No Connection IC decoder pin diagram Abstract:
