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. 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/EPF/LWF output source drivers are NPN Darlingtons capable of sourcing up to 40 mA. The DMOS active pull-downs are capable of sinking...
