PCA9534A: About power down

Masazumi Ishii

Part Number: PCA9534A

Hello,
I have a question about PCA9534A.

Is it OK to apply a signal (5 V applied) to the input when powering down?
conditions
Vcc = 0 V,
SDA, SCL = (5 V)
P1 = signal applied (5 V)

Thank you.

Hi Masazumi-San,

Our SDA, SCL and P I/O lines are 5-V tolerant as per datasheet spec. You also shouldn't be susceptible to back biasing under these conditions. Hope this helps.
