... The regulated current sources are designed to provide a constant current, which is adjustable through one external resistor. The TB62777FNG incorporates eight channels of shift registers, latches, AND gates and constant-current outputs. Fabricated using the Bi-CMOS process, the TB62777FNG satisfies the system requirement of high-speed data transmission. ...

... OUT7 SERIAL-OUT Note 1: Latches are level-sensitive, not edge-triggered. Note 2: The TB62777FNG 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 ...

... Otherwise, the current or power consumption may exceed the absolute maximum rating, and exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may result injury by explosion or combustion. In addition, do not use any device that is applied the current with inserting in the wrong orientation or incorrectly even just one time. TENTATIVE 15 TB62777FNG (Ver.0.2) 2008-1-23 ...
