2 / 17 page DM115B 點晶科技股份有限公司 SILICON TOUCH TECHNOLOGY INC. 8-BIT CONSTANT CURRENT LED DRIVERS with 3.3V~5V supply voltage Version:A.001 Page 1 DM115B 8-Bit CONSTANT CURRENT LED DRIVERS with 3.3v ~ 5v Supply Voltage General Description The DM115B is the constant current driver specifically designed for LED display applications. The value of constant current can be varied using an external resistor. The devices include an 8-bit shift register, latches, and constant current drivers on a single Silicon CMOS chip. Features Maximum Output Voltage: 17V Maximum Clock Frequency: 25MHz (Cascade Operation) Power Supply Voltage: 3.3V to 5.0V CMOS Compatible Input Package: PDIP16, SOP16, SSOP16 Package and Pin Layout: Pin layout and functionality are similar to those of the ST2221A. (Each characteristic value is different.) Constant Current Matching: (Ta = 25 °C、VDD = 5.0V) Chip-to-Chip: ± 10.0% Bit-to-Bit: ± 4.0% @ IOUT = 20 ~ 60mA ± 6.0% @ IOUT = 5 ~ 20mA |
