... LEDs and LED panel displays. The regulated current sources are designed to provide a constant current, which is adjustable through one external resistor. The TB62778FNG incorporates eight channels of shift registers, latches, AND gates and constant-current outputs. Fabricated using the Bi-CMOS process, the TB62778FNG satisfies the system requirement of high-speed data transmission ...

... OUT7 SERIAL-OUT Note 1: Latches are level-sensitive, not edge-triggered. Note 2: The TB62778FNG can be used at 3 5.0 V. However, the V voltage. Note 3: Serial data is shifted out of SERIAL-OUT on the falling edge of CLOCK. Note 4: The latches hold data while the LATCH terminal is held Low. When the LATCH terminal is High, the latches do not hold data and pass it transparently ...

... In total brightness adjustment mode, when LATCH is High, a brightness code in the shift register is latched into the brightness adjustment register instead of the output latches. Once latched into the brightness adjustment register, the brightness code is held until the TB62778FNG is powered off overwritten with a new code. Adjusting the total brightness ...
