Part Number: ISO7740 Tool/software: My customer needs to know the delay time until a valid output signal on OUTx is present for the VCC1 ramp-up phase in the case that there is a pull-up resistors to VCC1 at the INx pins.
Our datasheet only specifies…
Part Number: ISO7740 Hi everyone,
I am using this isolator and I would need to obtain different input and output voltages, specifically 5V input and 3V3 output. For this purpose, I wold like to know if I can supply this chip with different voltages…
Part Number: ISO7740 Other Parts Discussed in Thread: TXU0104 Hi,
@ questions as below need your support.
1. If customer don't use power isolation IC, the digital isolation IC still have a role?
2. Could this digital isolation IC be used with different…
Part Number: ISO7740-Q1 Hi Team,
I am using ISO7740FQDWQ1 in my design. My requirement is to have Two 4 channel isolators of one with 4 forward channels and other with 4 reverse channels. But ISO774x-Q1 family doesn't not have 4 reverse channels configuration…
There are 3 main ways to limit current into the device that can prevent damage to the isolation barrier in the event of a single side fault.
Method 1: Series resistor
A resistor in series with the I/O or supply rail is commonly used to limit the…
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…
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…
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…
