Description
TC62D749CFG
TOSHIBA CDMOS Integrated Circuit Silicon Monolithic
TC62D749CFG
16-Output Constant Current LED Driver (Output switching high-speed version)
The TC62D749CFG is a constant-current driver for LED and LED display lighting applications.
The output current from each of the 16 outputs is programmable via a single external resistor.
The TC62D749CFG contains a 16-channel shift register, a 16-channel latch, a 16-channel AND gate and a 16-channel constant-current output.
Fabricated with a CMOS process, the TC62D749CFG allows high-speed data transfer.
It operates with a 3.3- or 5-V power supply.
