JLC1562B

The JLC1562B facilitates easy I2C Bus expandibility. Multiple devices (up to 8 on the same I2C 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 I2C Bus.

I2C Bus interface pins SDA, SCL and A0−A2 are; Serial Data, Serial Clock and Device Address respectively. External interface pins are P0−P7 and VDAC; I/O Port and D/A output.
