My CD4050 is leaking voltage. User error?

Dec 23, 1. Jun 25, 11 0. I’ve taken a stab at getting some insight in the electronics stack exchange, and that led me to eventually order some fresh CD chips, thinking that the batch I ordered off eBay were either broken or mislabeled. Here’s the original post: So now I’m thinking that surely I must be in the wrong here.

This controller is 3. Adafruit’s tutorial recommends using a CD hex buffer. I read the datasheet, which explicitly advertises it as a logic level converter from high-to-low adtasheet of course.

The tutorial worked fine for me, but the screen was really faint, like it wasn’t getting enough power. I plugged the voltmeter into my 3. LM V-regulator powered via 5V wall-wart into one side of the breadboard daasheet 5V railand from there into Vin on the Arduino. I also experimented with disconnecting the V-reg and cd400 via USB 2. Power the CD from 3. Plugin the Voltmeter into ground and the Vcc of the chip. Insert a resistor from output 1 pin 2 into ground, and datasgeet into the 5V rail.

All other inputs and outputs are grounded. This is the WTF!? Disconnect power – voltmeter still reads 4. It’s these moments when I really wish I had a mentor. Anyone know of a good electronics club in Denver, CO? Thanks for any help, and ask away!

Datashee I’m going to be experimenting again with this. Should I order a 74HC? I see those mentioned a lot, but I don’t see any reason why these s Cr4050 have already should be misbehaving, unless all 22 of them are junk first order had 10, second order had Dec 23, 2.

Mar 14, 20, 5, Just a small cockpit error. There is an input protection diode from the cs4050 to the supply rail that will conduct when the input is more that about 0.

Thus the 5V is being conducted to the 3. I remember first experiencing this when I found that my CMOS circuit would operate when I fed a input signal from a pulse generate even though the power supply was off! It turned out the pulse generator low impedance output was supplying current to the power rail through the input diode, and that charged up the filter capacitors enough to operate the circuit.

Dec 23, 3. Nov 12, 3, 2, Dec 23, 4. Nov 30, 18, 9, So, the cure is: Dec 23, 5. Feb 24, 11, 2, The CD is nearly 45 years old. There are more modern parts that will do what you want without the side effects.

That is they will run from a 3. If you select the right parts they will also work the other way by shifting 3. Using this part is in the same category as using a opamp. Why would you do such a thing?

Dec 23, 6. I’ll try the resistor again tonight, that was recommended on the stack exchange forum, and I did try it, but without success So I can’t hook up c4d050 5V input, that seems to go against what I’m reading in lots of places: Dec 23, 7. Dec 23, 8. Give this a read. Dec 23, 9.

I’ve mentioned these chips in previous posts. Dec 23, The input-signal high level VIH can exceed the VCC supply voltage when these devices are used for logic-level conversions.

Those voltages define for a part the input-high voltage and the input low voltage. For example look at Table 9 in the 74HC spec and notice that the actual thresholds depend on Vcc! The CMOS output high voltage equals the supply voltage with no load.

So if the supply is 3. Dec 24, Poked around Adafruit’s forums just now, and I’m having the identical problems as this guy: Embedded Systems and Microcontrollers. Lead-Acid battery charger – leaking voltage?
