The power supply range of 3 volts to 16 volts and Maximum power supply voltage at pin 1 must not much than 18 volts.

HCFBE Datasheet, PDF – Alldatasheet

The output would be low and on rings go high. It has 16 pins and looks like any other 16 pin integrated circuit. A number of B IC circuits can be connected together by connecting pin 10 divide by 10 pin to the input on the next Ucfbe IC. Maybe use that with a gate for pin 15 Reset?

Yes, the in the design is set to count to N ucf4017be recycle so it waits till it gets to N regardless of where the pulses clock is from.

On reaching “9” again returns to “0” and so on. HCFBE I have suffered dataaheet displeasing feature most times useful of this hct4017be, When the clock advances, decade counting also advances from 0 to 9 then 0 to 9 and so on.

Where I have made a slight change to fulfill my requirement I think this would be a simpler version than all circuits presented by ddatasheet here. That is five LOW-to-HIGH clock ring edges detected, then when goes to “6” out the counter automatically reset by the arrangement shown in schematic.


The pulse datasheef the timer can be used hcfbe datasheet activate the B circuit. Boncuk New Member Feb 25, Pin 16 is positive hcfbe datasheet supply and pin 8 is hcfbe datasheet ground.

Datasheet search engine for Electronic Components and Semiconductors. The B is most useful when combined with a timer such as a based circuit. This can all be done with a 74c This really neat chip contains a counter and a decoder circuit, that can show a single output pin for each count from 0 to 9. See my attached link ” in first post.

Maybe off topic but I always wondered about this part: The pulse hcfbe datasheet the IC is generated from pin 3. But the problem fatasheet that when we power up the circuit again, the counter starts from out “9” not from initial “0” when detecting first LOW-to-HIGH clock edge.

What pin is it connected to?

See the attachment in this last thread. My circuit only accepts a coded number of rings. Pin 13 has Clock enabled pins to controls the clock. The result energises a relay for 60 seconds. The IC counts with 5 D-type flip-flops.

The B is an integrated circuit hcfbe datasheet has been designed to count pulses. See detailed ordering and shipping information datwsheet the package dimensions section on page 7 of this data sheet. But look up other attachment. The monostable datahseet initiated by the first positive clock edge at pin 14 CLK. An 8 pin PIC chip and 6 components is all you need.

When we build hcfbe datasheet 10 LEDs running light for a hobby. They are versatile and relatively simple to put together. Articles Top Articles Search resources. Counters hcfbe datasheet hcfbs the B are cheap and yet surprisingly useful.



Add a timer to dztasheet datasheet decade counter. I have been in the phone tapping and phone coding business for over 20 years. Your circuit is quite useless.

This is one example of why I design with a microcontroller. But in practice we can neglect it as not affecting our project aim in any way.

HCF4017BE Decade Counter with 10 Decoded Outputs

Welcome to our site! Decoding and control hcfbe datasheet by 16 inverters and 15 gates. Look at the Figure below is a block diagram of inside IC The next one is not hcfbe datasheet. If I would get such a counter I will add one relay at the output of opto-coupler, which will close power up connection of my counter when first ring signal occurs. So Quasi length 0. But what happened when someone wouldn’t complete 5 rings missed call? Let us assume he disconnect his phone on dataheet ring.

In most applications this hcv4017be a good feature.

STMicroelectronics HCFBE – PDF Datasheet – Series In Stock |

Hi, I modified the circuit to automatically reset independent of the number of rings. A astable circuit is used to pulse the B at regular intervals. You would need to calculate the time approximately between rings Pulses on ring signal and datsheet things up as a retriggerable one shot. Chfbe 12 is Carry output, for the clock input of an additional counter or an external circuit that hcfbe datasheet count is complete.
