Designed primarily to drive vacuum-fluorescent displays, the 60 V and -40 mA output ratings also allow these UCN5810AF, UCN5810EPF, and UCN5810LWF to be used in many other peripheral power driver applications. The UCN5810AF, UCN5810EPF, and UCN5810LWF feature reduced supply requirements (active DMOS pull-downs) and lower saturation voltages when compared with the original UCN5810A.
The CMOS shift register and latches UCN5810AF, UCN5810EPF, and UCN5810LWF allow direct interfacing with microprocessor-based systems. With a 5 V supply, they will operate to at least 3.3 MHz. At 12 V, higher speeds are possible. Use with TTL may require appropriate pull-up resistors to ensure an input logic high.
A CMOS serial data output of UCN5810AF, UCN5810EPF, and UCN5810LWF enables cascade connections in applications requiring additional drive lines. Similar devices are available as the UCN5811A (12 bits), UCN5812AF/EPF (20 bits), and UCN5818AF/EPF (32 bits).
The UCN5810AF, UCN5810EPF, and UCN5810LWF output source drivers are NPN Darlingtons capable of sourcing up to 40 mA. The DMOS active pull-downs are capable of sinking up to 15 mA. For inter-digit blanking, all of the output drivers can be disabled and the DMOS sink drivers turned on by the BLANKING input high.
The UCN5810AF is furnished in an 18-pin dual in-line plastic package. The UCN5810EPF is furnished in a 20-lead plastic chip carrier. The UCN5810LWF is furnished in a wide-body, small-outline plastic package (SOIC) with gull-wing leads. Copper lead frames, reduced supply current requirements, and lower output saturation voltages allow all devices to source 25 mA from all outputs continuously, over the entire operating temperature range. UCN5810AF, UCN5810EPF, and UCN5810LWF are also available for operation between -40°C and +85°C. To order, change the prefix from 'UCN' to 'UCQ'.
