DM134、DM135、DM136 DM134、DM135、DM136 16-Bit Constant Current LED Drivers General Description The DM134、DM135、DM136 are constant current drivers specifically designed for LED display applications. The value of constant current can be varied using an external resistor. The devices include a 16-bit shift register, latches, and constant current drivers on a single Silicon CMOS chip. Features 5V CMOS patible Input Maximum Clock Frequency: 25MHz (Cascade Operation) Maximum Output Voltage: 17V Package: DIP24, SOP24, SSOP24, QFN32, TSSOP24-exposed PAD(DM135) Package and Pin Layout: Pin layout and functionality are similar to those of the ST2221C. (Each characteristic value is different.) Constant Current Matching: (Ta = 25°C、VDD = 5.0V) Chip-to-Chip: ± 10.0% Bit-to-Bit: DM134: ± 4.0% @ IOUT = 30 ~ 90m A ± 6.0% @ IOUT = 20 ~ 30m A DM135: ± 4.0% @ IOUT = 10 ~ 50m A ± 6.0% @ IOUT = 5 ~ 10m A DM136: ± 4.0% @ IOUT = 3 ~ 15m A 16-Bit Constant Current LED Drivers -1- Version：A.013 ..net 點晶科技股份有限公司 SILICON TOUCH TECHNOLOGY INC.
