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 LEDS.

Applications
Printers, mini-component stereo systems, car audio systems, and musical instruments
•
Features
1) Regardless of the clock and data input, the CLR pin
resets the latch circuit, and sets all outputs to the low
level.
2) Output drive capacity: 25mA / output (Max.).
3) Input pin hysteresis: 0.5V (Typ.).
