JLC1562B
I2C Bus I/O Expander
2
The JLC1562B facilitates easy I C Bus expandibility. Multiple
2
devices (up to 8 on the same I C Bus) are easily added as each device
has its own selectable 3−bit address. The JLC1562B provides an 8−bit
bidirectional input/output port and 6−bit resolution Digital to Analog
Converter. The voltage on pins P0−P4 is compared with a controllable

threshold voltage and the results are readable through the I C Bus.
