●Description Serial-in-parallel-out driver incorporates a built-in shift register and a latch circuit to control a maximum of 24 LED by a 4-line interface, linked to a microcontroller. A single external resistor can set the output current value of the constant current up to a maximum of 50mA. (BD7851FP only) CMOS open drain output type products can drive the maximum current of 25mA.
●Features 1) LED can be driven directly. 2) Parallel output of a maximum of 24 bit 3) Operational on low voltage (2.7V to 5.5V) 4) Cascade connection is possible (BU2050F and BU2092F,BU2092FV are not acceptable)
●Application For AV equipment such as, audio stereo sets, videos and TV sets, PCs, control microcontroller mounted equipment.
