L16B45A Datasheet (UTC) - 16-BIT CONSTANT CURRENT LED SINK DRIVER

L16B45A, 16-BIT CONSTANT CURRENT LED SINK DRIVER

The UTC L16B45A is designed for LED displays.

UTC L16B45A contains a serial buffer and data latches which convert serial input data into parallel output format.

At UTC L16B45A output stage, sixteen regulated current ports are designed to provide uniform and constant current sinks for driving LEDs wi
