Designed primarily for use with vacuum-fluorescent displays, the UCN5811A smart power BiMOS II driver features low-output saturation voltages and high output switching speed. These devices contain CMOS shift registers, data latches, and control circuitry, and bipolar high-speed sourcing outputs with DMOS active pull-down circuitry. The high-speed shift register and data latches allow direct interface with microprocessor-based systems. A CMOS serial data output enables cascade connections in applications requiring additional drive lines.
