TB62777FNG/FG
TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic
TB62777FNG, TB62777FG
8-Channel Constant-Current LED Driver of the 3.3-V and 5-V Power Supply Voltage
Operation
The TB62777FNG/FG is comprised of constant-current drivers
designed for LEDs and LED panel displays.
The regulated current sources are designed to provide a
constant current, which is adjustable through one external
resistor.
The TB62777FNG/FG incorporates eight channels of shift
registers, latches, AND gates and constant-current outputs.
Fabricated using the Bi-CMOS process, the TB62777FNG/FG is
capable of high-speed data transfers.
The TB62777FNG/FG is RoHS.

Note 1: For cascade operation, the CLOCK waveform might become ambiguous, causing the tr and tf values to be
large. Then it may not be possible to meet the timing requirement for data transfer. Please consider the
timing carefully.
Note 2: Please see the timing waveform on page 9.
