General Description

The DM134B、DM135B 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.

Key Features

  • 3.3V~5V CMOS Compatible Input Maximum Clock Frequency: 25MHz (Cascade Operation) Maximum Output Voltage: 17V Package: DIP24, SOP24, SSOP24, QFN32 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: DM134B:± 4.0% @ IOUT = 30 ~ 90mA ± 6.0% @ IOUT = 20 ~ 30mA DM135B:± 4.0% @ IOUT = 20 ~ 60mA ± 6.0% @ IOUT = 5 ~ 20mA 16-Bit Constant Curr.
