CMOS shift register and accompanying data latches, control circuitry, bipolar

sourcing outputs with DMOS active pull-downs. Designed primarily to drive

vacuum-fluorescent displays, the 60 V and -40 mA output ratings also allow

these devices to be used in many other peripheral power driver applications.

The UCN5810AF/EPF/LWF feature reduced supply requirements (active

DMOS pull-downs) and lower saturation voltages when compared with the

original UCN5810A.

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.

requiring additional drive lines. Similar devices are available as the

UCN5811A (12 bits), UCN5812AF/EPF (20 bits), and UCN5818AF/EPF (32

bits).

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 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. All devices are also available for operation between -40°C and +85°C.

To order, change the prefix from ‘UCN’ to ‘UCQ’.
