# CD4041UB: TSSOP14

Part Number: CD4041UB

Hi ,

I want to use CD4041UBPWR ,it is new componnent for me , can you PLS tell my about the relability of the CD4041UBPWR?

Thank you.

• Hi Ilan,
And click any of the links in the DPPM / MTBF / FIT Rate column for details.
• Hi,

in order to gate more current can i shorts the inputs to the input signal ,then short the outputs to the output signal?

BR,

Ilan

• Ilan,

please let us know your requirement in terms of voltage and current.
We might have high drive device which might fit.
• 12-14mA sink and source.

20mA MAX sink and soruce

• 12-14mA sink and source with 10v high and 0.5v low.

20mA sink and source.

PLS  answer for my question before.

I mean shorting inputs and outpts.

Thanks

Ilan

• Hi Ilan,
Yes, channels inside the same CD4041UB can be paralleled to increase current output. Do not exceed 100mW per channel, or the device could be damaged (see the absolute maximum ratings table).
• Hi Emerys,

How much current sink and source is 100mW per channel  when VDD=10V at output?

How the current at output is sharing  between the channels I was connected together?

Thanks

• Hi Ilan,
Power is current times voltage, or P = IV

The voltage is the supply minus the output high voltage (given in the datasheet for select test currents), and the current is the output current.

Current will be approximately equal between the outputs. For example, if you are driving 10mA at 10V, the output voltage is listed as 9.5V, thus the power consumption per channel is:

P = 0.010 * (10-9.5) = 5mW

If two channels are put in parallel, you can expect to reduce the resistance by half, thus reducing the voltage drop by half, and reducing the power by half:

P = 0.005 * (10-9.75) + 0.005 * (10-9.75) = 2.5mW
