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,
