Serial-in / Parallel-out Driver Series
Serial / Parallel
4-input Drivers
BU2050F,BU2092F,BU2092FV,BU2099FV,BD7851FP,BU2152FS
No.09051EAT03
●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.
