Part Number: ISO7740 Hi,
The customer wants to know the minimum pulse width of the input signal. The DS shows the maximum data rate. max data rate 100Mbps-> 10ns period At 50% duty, the minimum pulse width is 5ns.
The customer's system is not a perfect…
Part Number: ISO7740 Hi Team,
Datasheet says tplh, tphl is 6~16ns for 5V Vcc and 15pF CL
Customer wants to know will tpd be smaller if smaller CL such as 2pF is used?
And is it possible to estimate tpd value corresponding to CL value?
Thanks.
Regards,
…
Part Number: ISO7740 Hi Team,
My customer is surveying ISO774x and has a question about power rating.
Below table shows that ISO7740 still can handle 200mW power dissipation at Tj=150C, but datasheet also shows the Max. Tj is 150C. So, when Tj=150C any…
Part Number: ISO7740 Dear:
ISO7740FDBQ is current out of stock, May I use ISO7740FQDBQ replace it directly ? I saw the datasheet shows it is ok, could you help me confirm whether need change any schematic or any points ?
Part Number: ISO7740 Hi team,
My customer is using the ISO7740 as the 485 isolation. Currently we have a new isolation for a LED which need 4ma.
From the datasheet it cannot support 4ma or 15ma. We want to check whether the 4ma will influence other channel working…
Part Number: ISO7740 Hi,
In design, ISO7740 output channels (each channel) are connected to LED for indication. The LED sink current is around 3mA.
Whether output channels (each channel) are able to handle the 3mA current (sink) ?
Please clarify. Below…
Part Number: ISO7740 Hi,
ISO7740 in datasheet spec. 7.1 Io output current shows one channel or four channel total current as below? I want to know it ,many thanks~
Part Number: ISO7740-Q1 Hi team,
I am trying to calculate the power draw in the worst case for the ISO7740FQ1 isolator IC. For static DC signals the power draw is assumed constant, right? Also assuming all channels (4 inputs) are high would the total…
