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 equal-
ization 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.
s Features
• Serial-in, serial-out/parallel-out
• Cascade connection possible
• Constant current output (0 to 100 mA able to be set by
one external resistor)
• Output-forced ON/OFF terminal attached (EN)
• Input/Output CMOS compatible
s Application
• LED panel drive
