I2C Bus I/O Expander 16-Pin SO EIAJ T/R

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 Cl Deg Ck and Device Address respectively. External interface pins are P0-P7 and VDAC; I/O Port and D/A output.
