Product data  
8-bit I2C and SMBus I/O port with interrupt,  
2-kbit EEPROM and 6 address pins  
PCA9501  
Quasi-bidirectional I/Os (see Figure 8)  
A quasi-bidirectional I/O can be used as an input or output without the use of a control signal for data direction. At power-on the I/Os are HIGH.  
In this mode, only a current source to V is active. An additional strong pull-up to V allows fast rising edges into heavily loaded outputs.  
DD  
DD  
These devices turn on when an output is written HIGH, and are switched off by the negative edge of SCL. The I/Os should be HIGH before  
being used as inputs.
