Manufacturer Part Number
jlc1562be
Description
I2c Bus I/o Expander
Manufacturer
ON Semiconductor
Datasheet
JLC1562B
I
devices (up to 8 on the same I
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
Serial Clock and Device Address respectively. External interface pins
are P0−P7 and VDAC; I/O Port and D/A output.
