Description
Serial-in-parallel-out driver is a open drain output driver. It incorporates a built-in shift register and a latch circuit to turn on a
maximum of 12 LED by a 2-line interface, linked to a microcontroller.
A open drain output provides maximum of 25mA current.
Features
1) LED can be driven directly. (Output current 25mA)
2) 8/12 Bit parallel output
3) This product can be operated on low voltage.
4) Compatible with I2C BUS. (BU2098)
Use
For AV equipment such as, audio stereo sets, videos and TV sets, PCs, control microcontroller mounted equipment.
