My intent is to have the driven by a timer in monostable mode, that can be switched between the Up and Down inputs a switch between Ground and Pin 2 would send a pulse to to input datasheet either the Up or Down input of the Tl warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with Tl’s standard warranty.

Swtpc at English Wikipedia. Jun 30, 5. Not recommended for new designs. Reproduction of Tl information in Tl data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and datashet.

74192 Up/Down counter problems…

This component has a RoHS exemption for either 1 lead-based flip-chip solder bumps used between the die and package, or 2 lead-based die adhesive used between the die and leadframe. Customers should contact their board assembly site for stencil design recommendations.

Device is in production to support existing customers, but Tl does not recommend using this part in a new design. In fact, i’ll post a circuit diagram sometime tomorrow so no one else ever has these problems.


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. Apr 26, 3, 1, But when I hooked them up to the inputs one to the Up and one to the Downthe display when all haywire, as though the button was just held low, and it just kept cycling through digits.

Resale of Tl products or services with statements different from or beyond the parameters stated by Tl for that product or service voids all express and any implied warranties for the associated Tl product or service and is an unfair and deceptive business practice. To minimize the risks associated with customer products and applications, customers should datashset adequate design and operating safeguards.

Similarly, datashset carry output produces a pulse equal in width to theborrow and carry outputs to the count-down and count-up inputs respectively of the succeeding counterNOM 5 M AX 5. Interlead flosh shall not exceed.

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. Jun 30, 6. Clear outputs to zero. Customers are responsible for their products and applications using Tl components. Tl has announced that the device will be discontinued, and a lifetime-buy period is in effect.

The following other wikis use dataheet file: Jul 2, Following are URLs where you can obtain information on other Texas Instruments products and application solutions: Tl products are not authorized for use in safety-critical applications such as life support where a failure of the Tl product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use.


If you want to try a kludge, add a 4.

This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. Tl is not responsible or liable for any such statements.

According to the datasheett for thethe input that are not datasheeet use want to be kept high, while the few circuits i’ve seen keep them low. Apr 20, 15, Previous 1 2 If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. The pulse generators have the following characteristics: What is the part number on your timer?

Your name or email address: Datashet of third parties may 74129 subject to additional restrictions. GND via 10k resistor Tl is not responsible or liable for such altered documentation. The output will change to agree with the data In- puts independently of the count pulses.

In some countries this may not be legally possible; if so: It pulses at a rate of about ms High-Low as per its configuration so I doubt that it’s the problem. Addendum-Page 3 Texas Instruments www.
