The A6812ELW from Allegro Microsystems is a 20-bit serial-input latched source driver, part of the DABiC-IV family. This device integrates a CMOS shift register, data latches, and control circuitry with bipolar sourcing outputs and PNP active pull-downs. It is primarily designed for driving vacuum fluorescent displays but is also suitable for various peripheral power driver applications due to its 60V output breakdown and -40mA output ratings.
The A6812ELW features an increased data-input rate and a controlled output slew rate, reducing electromagnetic noise. Its CMOS shift register and latches allow direct interfacing with microprocessor-based systems, operating at speeds up to 10 MHz with a 3.3V or 5V logic supply. A CMOS serial data output enables cascaded connections for applications requiring additional drive lines.
This component is available in a 28-SOIC package with surface mount capability. It offers a 1:20 ratio, 20 outputs, and operates within a temperature range of -40°C to 85°C. The A6812ELW is an improved replacement for older series like TL5812x, UCN5812x, and UCQ5812x.
Key electrical characteristics include a 3V to 5.5V operating voltage range and a 40mA current capability per output. The output type is bipolar, and the output configuration is high side. The interface includes serial and strobe capabilities, with a non-inverting input type.
