Other Parts Discussed in Thread: ULN2803A
Hi all,
I'm trying to change my older PCF8574AP marked NXP with the PCF8574AN marked Texas Instrument, the problem is that with a working board mounted with the PCF8574AP the Output (2803+relay) works well, if I change with the new device no outputs work. The I2C address is set to be 0x7E. Any idea?
Thanks.
