Part Number: SN65LBC180 Hi team,
My customer doesn't need enable function.
So, the customer should tied /RE pin to GND. Is my understanding correct?
Regards,
Yoshi
Part Number: SN65LBC180-Q1 Hi team,
When my customer checked qualification summary of SN65LBC180-Q1, the ESD of CDM and HBM mentioned "See datasheet" as below picture.
I can see the HBM is 15kV when I use parametric search of the device.

I would like to have RS232 and RS485 can be choice by GPIO circuit.
I find this in TI http://www.ti.com/lit/ug/tidua80/tidua80.pdf .
If I let B short to Z, A short to Y, one 120ohm between…
Part Number: SN65LBC180 Hi!
Could you please let me know what is the impedance of output pins - Y/Z/R?
Just wondering if it is 50 ohms.
Here is how the test path looks like : ATE driver --> ATE trace --> PCB trace ---> device input
The ATE driver…

Part Number: SN65LBC180 Hi!
Could you please let me know what is the impedance of input pin - D?
It is not listed in datasheet, I am seeing the signal reflection and guess it is not 50 ohms impedance.
Here is how the test path looks like : ATE driver…
Hello Michael,
Thank you for your reply.
I tell my customer as follows.
It is no problem to make transmission permission (DE=High) always.
Regardless of a state of the DE, use it in "Recommended Operating Conditions".
If my customer give…
Other Parts Discussed in Thread: SN65LBC180 Hi,
I would like you to confirm whether there is any requirement of wait time when user can input REn signal to output Received signal.
Does user need to wait a few second after Vcc is stable ?
If you have requirement…
Other Parts Discussed in Thread: SN65LBC180 Hello, I have a question about SN65LBC180.
The standard of RS-485 defines the differential signal in +200mV or more as High and defines it in -200mV or less as Low. SLLS174G describes "FUNCTION TABLES" in the page…
