These 32-bit drivers have bipolar open-collector Darlington outputs, CMOS data latch each drivers, 32-bit CMOS shift register, CMOS control circuitry. high-speed CMOS shift registers latches allow operation with most microprocessor-based systems data input rates above MHz. these drivers with require input pull-up resistors ensure input logic high. UCN5833A supplied 40-pin dual in-line plastic package with 0.600" (15.24 spacing. ambient temperature +75°C, outputs DlP-packaged device will sustain continuously. high-density applications, UCN5833EP available. This 44-lead plastic chip carrier (quad pack) intended surface-mounting solder lands with 0.050" (1.27 centers. CMOS serial data outputs permit cascading applications requiring additional drive lines.

Serial Data present input transferred shift register logic logic transition CLOCK input pulse. succeeding CLOCK pulses, registers shift data information towards SERIAL DATA OUTPUT. SERIAL DATA must appear input prior rising edge CLOCK input waveform. Information present register transferred respective latch when STROBE high (serial-to-parallel conversion). latches will continue accept data long STROBE held high. Applications where latches bypassed (STROBE tied high) will require that OUTPUT ENABLE input during serial data entry. When OUTPUT ENABLE input low, output buffers disabled (OFF) without affecting information stored latches shift register. With OUTPUT ENABLE input high, outputs controlled state latches.
