8-bit serial in, parallel out driver IC
BU2050F
The BU2050F is a driver IC that is comprised of an 8-bit shift register and a latch (serial in / parallel out). The data
read into the shift register can be asynchronously latched. The CMOS outputs can provide 25mA (Max.) of current
per output, making this IC ideal for a wide range of applications including driving LED
