1 / 8 page DISCONTINUED PRODUCT — FOR REFERENCE ONL Y HIGH-VOLTAGE BiMOS III 10-BIT SERIAL-INPUT, LATCHED DRIVERS Always order by complete part number, e.g., UCN5910A-2 . The UCN5910x combines a 10-bit CMOS shift register and accompanying data latches, control circuitry, high-voltage bipolar sourcing outputs with DMOS active pull-downs. Designed primarily to drive ink-jet and piezoelec- tric printers, large flat-panel vacuum-fluorescent or ac plasma displays, the 140 V or 150 V and ±50 mA output ratings also allow these devices to be used in many other peripheral power driver applications. The lower-cost (suffix “-2”) devices are identical to the basic devices except for output voltage rating. The CMOS shift register and latches allow direct interfacing with micro- processor-based systems. With a 5 V logic supply, serial-data input rates are typically over 5 MHz, with significantly higher speeds obtainable at 12 V. 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 for up to 60-volt operation are available in 10, 12, 20, and 32-bit configurations. The UCN5910A/LW output source drivers are npn Darlingtons capable of sourcing at least 40 mA. The DMOS active pull-downs are capable of sinking at least 30 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 UCN5910A and UCN5910A-2 are furnished in a 20-pin dual in-line plastic package. The surface-mount UCN5910LW and UCN5910LW-2 are 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 be operated at ±20 mA from all outputs (50% duty cycle), at ambient temperatures up to +30 °C, or at ±15 mA to +55 °C.
