SUB
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 piezoelectric 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 microprocessor-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 +30C, or at 15 mA to +55C.

Serial Data present at the input is transferred to the shift register on the logic "0" to logic "1" transition of the CLOCK input pulse. On succeeding CLOCK pulses, the registers shift data information towards the SERIAL DATA OUTPUT. The SERIAL DATA must appear at the input prior to the rising edge of the CLOCK input waveform. Information present at any register is transferred to the respective latch when the STROBE is high (serial-to-parallel conversion). The latches will continue to accept new data as long as the STROBE is held high. Applications where the latches are bypassed (STROBE tied high) will require that the BLANKING input be high during serial data entry. When the BLANKING input is high, the output source drivers are disabled (OFF); the DMOS sink drivers are ON. The information stored in the latches is not affected by the BLANKING input. With the BLANKING input low, the outputs are controlled by the state of their respective latches.
