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 Compatible Input Maximum Clock Frequency: 25MHz (Cascade Operation) Maximum Output Voltage: 17V Package: DIP24, SOP24, SSOP24, QFN32, TSSOP24-exposedPAD(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 ~ 90mA ± 6.0% @ IOUT = 20 ~ 30mA DM135: ± 4.0% @ IOUT = 10 ~ 50mA ± 6.0% @ IOUT = 5 ~ 10mA DM136: ± 4.0% @ IOUT = 3 ~ 15mA 16-Bit Constant Current LED Drivers -1- Version：A.013 www.DataSheet4U.net SILICON TOUCH TECHNOLOGY INC.
