JLC1562B Datasheet, PDF (1/10 Pages) ON Semiconductor – I2C Bus I/O Expander

JLC1562B
I²C Bus I/O Expander
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.
Features
• Pb−Free Packages are Available*

• Bus Address Selectable (3−bit)
• Address Input Pins are Pulled Up to V_DD with Internal Resistor
• I/O Pins are Open Drain Outputs
• 5 Comparators at Inputs
• Inputs Protected from External Bus Currents in Power Down Mode
