Description

The A6810 combines 10-bit CMOS shift registers, ac com pa ny ing data latches, and control cir cuit ry with bipolar sourcing out puts and PNP active pull-downs. De signed pri mar ily to drive vacuum-flu o res cent (VF) displays, the 60 V and –40 mA output ratings also allow this device to be used in many other peripheral power driver ap pli ca tions. The A6810 features an increased data input rate (com pared with the older UCN/UCQ5810-F) and a con trolled output slew rate.

The CMOS shift register and latches allow direct interfacing with microprocessor-based systems. With a 3.3 or 5 V logic supply, serial data-input rates of at least 10 MHz can be attained

A CMOS serial data output permits cascaded connections in ap pli ca tions re quir ing additional drive lines. Similar devices are available as the A6812 (20-bit) and A6818 (32-bit).
