- Equivalent of IC4026 - Electrical Engineering Stack Exchange
The 4017 is a decade counter with decoded one-hot outputs, while the 4026 is a decade counter with decoded 7-segment outputs Here are the data sheets for the 4017 and the 4026 Share
- 7segmentdisplay - 4026 + 7-segment display: do I need transistors . . .
Alternatively you may use low-power Schottky ICs, but then you'll need the counter and the display decoder separately; I don't think the combination like the 4026 exists in LS-TTL The 74LS90 is a decimal counter, and the 74LS247 a 7-segments decoder, which can drive LEDs directly This is also an active low output IC, which means common anode:-(
- How to sink current to drive 7-segment LED using a 4026 chip?
Resistors are not required for the LEDs because the 4026 IC limits the current to about 5mA for each LED; Who says so? AFAIK this is not the case for this chip When you read the datasheet it might state that the "maximum is 5 mA", but that means that YOU must limit the current to 5mA, by using a suitable series resistor in each segment
- Reset pin (15) behaviour of 4026 counter - Electrical Engineering Stack . . .
I'm trying to play with CD4026BE counter and I'm unable to solve the problem with reset pin (15 according to datasheets and numerous examples) In my case, if pin 15 (reset) is grounded with the w
- design - How to reset a 4026 counter IC when it reaches 6 for . . .
The counter, i e 4026, that you specify is a device already containing the 7-segment decoder Plus this counter is not really suitable to the application where you want it to count from 1 through 6 Instead look at using a counter such as a 74HC161 This can be hooked up as shown below to make it count from 1 through 6
- Power On Reset on CD4026 IC - Electrical Engineering Stack Exchange
Your power on reset circuit doesn't make sense The reset pin is always tied to ground via the resistor This is a conventional power on reset circuit for pulsing the reset pin high at power on to reset a 'reset pin high' chip
- 7-segment display driver IC [closed] - Electrical Engineering Stack . . .
Which IC can I use to control 7-segment display? I want to make simple projects like a reaction timer but I don't have an Arduino or some other microcontroller available
- Voltage-Divider for High Voltages - Electrical Engineering Stack Exchange
The signals are all DC and the voltages are measured using a 1:1000 HV probe (CalTest CT 4026, 200 MOhm input impedance) connected to a Rigol oscilloscope (MSO5074, 1 MOhm input impedance) However, what I find is that the voltage divider does not work as intended
