Serial-in / Parallel-out Driver Series
Serial / Parallel
5-input Driver
BA829
No.09051EAT02
●Description
Serial-in-parallel-out driver is a constant-current output driver with a built-in shift register and a latch circuit to turn on a
maximum of 8 LED by a 5-line interface linked to a microcontroller. Output current value of constant-current can be set up to
a maximum of 300mA.
●Features
1) This product can drive a maximum of 300mA.
2) When the strobe terminal is controlled by the drive timing pulse, current during a period without driving can be reduced.
3) When the data output terminal is used as the next input data, cascade connection becomes possible.
4) Digital ground and power ground are separated.
5) Latch is built in between the shift register and the driver output.
6) Stand-by function is incorporated. (10μA Typ. upon standby)
●Applications
For AV equipment such as, component stereo sets, videos and TV sets, PCs, and control microcontroller mounted equipment.
