Overview
Others DN8667NS 8-Bit Shift Register Latch Constant Current Driver IC s Overview The DN8667NS is a semiconductor integrated circuit which incorporates a 8-bit shift register, a latch driver and a constant current driver to satisfy the demand for equalization of LED panel brightness.
It also incorporates the serial-in and serial-out/parallel-out functions.
It employs the Bi-CMOS process : The 8-step shift register block and latch block consist of CMOS while the 8-step parallel driver block is bipolar.
