UCN5810LWF Datasheet | Allegro MicroSystems

duced supply requirements (active DMOS pulldowns) and lower saturation voltages when pared with the original UCN5810A. The CMOS shift register and latches 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 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/LWF output source drivers are NPN Darlingtons capable of sourcing up to 40 m A. The DMOS active pull-downs are capable of sinking up to 15 m A. 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 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 m A from all...
