产品说明
DM115工作电压3.3V-5V 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
