Q1 is the first bit in the counter. Lets do a quick truth table to confirm: Then the output pins will go high at the following time intervals shown in table datxsheet. Using the CD binary counter IC is pretty simple.

Having the higher order bits is in many applications more useful than the low order bits, so the designer chose to break them out.

Posted by Nser Uame in forum: Submitted by webmaster on 1 October A clear input is used. For example let datashset assume an Astable clock input with a frequency of 1Hz from a timer is connected to clock pin.

As I cd datasheet the data sheet, the maximum output current both high and low output is 3. Need help with counter Posted by ctonton in forum: Showing first 20 results. That current decreases if the part cd datasheet warm. However instead of incrementing the output on each pulse, the CD’s output gets incremented on each eighth pulse.

All information provided in this document is subject to legal disclaimers. IC CD timer circuit Abstract: To be a little nit-picky, it’s not clocked and it’s negative edge sensitive. So if you are looking for a bit binary counter which can be incremented through a clock pulse then this IC might be of interest to you. The answer will depend on looking back in time at old circuits from the early ’90’s to see what they were using the part for. From Q1 you will get a nice digital clock signal out, albeit at half the frequency of the oscillator.

Quote of the day. This sort of signal is no good for feeding standard digital logic, but the CDB uses a Schmitt trigger input to clean it up.

For each clock signal the binary value gets incremented by one. But, Alexander, the information is otherwise completely correct: Both devices are incremented on the falling edge negative transition of the input clock, and all their outputs are reset to a low level by applying a logical high on their reset input.
