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. http://onsemi.com MARKING DIAGRAMS PDIP−16 N SUFFIX CASE 648 Features • • • • • • • • • Low Power Dissipation I2C−Bus Format (2−Wire Type; SDA, SCL) Data Transfer 6−bit DAC Bus Address Selectable (3−bit) Address Input Pins are Pulled Up to VDD with Internal Resistor I/O Pins are Open Drain Outputs 5 Comparators at Inputs Inputs Protected from External Bus Currents in Power Down Mode Pb−Free Packages are Available* A0 1 16 VDD A1 2 15 SDA A2 3 14 SCL P0 4 13 VDAC P1 5 12 P7 P2 6 11 P6 P3 7 10 P5 VSS 8 9 P4 1 Chip Address Input Comparator Input / Open Drain Output P5−P7 Comparator Input / Open Drain Output SCL Serial Clock Input SDA I2C Data Output VDAC DAC Output 1 SOEIAJ−16 F SUFFIX CASE 966 1 JLC1562B ALYWG 1 A WL, L YY, Y WW, W G = Assembly Location = Wafer Lot = Year = Work Week = Pb−Free Package ORDERING INFORMATION PIN LIST P0−P4 JLC1562BN AWLYYWWG 16 Device Package Shipping † JLC1562BN PDIP−16 25 Units/Tube JLC1562BNG PDIP−16 (Pb−Free) 25 Units/Tube JLC1562BF SOEIAJ−16 50 Units/Rail JLC1562BFG SOEIAJ−16 (Pb−Free) 50 Units/Rail JLC1562BFEL SOEIAJ−16 2000/Tape & Reel JLC1562BFELG SOEIAJ−16 (Pb−Free) 2000/Tape & Reel Figure 1.
