4-input Drivers
BU2050F,BU2092F,BU2092FV,BU2099FV,BD7851FP,BU2152FS
No.09051EAT03
âDescription
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.
âFeatures
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)
âApplication
For AV equipment such as, audio stereo sets, videos and TV sets, PCs, control microcontroller mounted equipment.
