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.
