merging low-power CMOS logic bipolar output power drivers permit UCN5841/42A A5841SLW integrated circuits used wide variety peripheral power driver applications. three devices this series each have eight-bit CMOS shift register CMOS control circuitry, eight CMOS data latches, eight bipolar current-sinking Darlington output drivers. Darlington outputs, with integral transient-suppression diodes, suitable with relays, solenoids, other inductive loads. Except maximum driver output voltage ratings, UCN5841A, A5841SLW, UCN5842A identical. UCN5842A offers premium performance with minimum output-breakdown voltage rating sustaining). drivers operated with split supply where negative supply BiMOS devices have higher data-input rates than earlier BiMOS circuits. With logic supply, they will typically operate better than MHz. With supply, significantly higher speeds obtained. CMOS inputs compatible with standard CMOS NMOS logic levels. circuits require appropriate pull-up resistors. using serial data output, drivers cascaded interface applications requiring additional drive lines. Suffix devices furnished standard 18-pin plastic DIP; suffix `LW' indicates 20-lead wide-body SOIC.

TYPICAL OUTPUT DRIVER
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 ENABLE input high during serial data entry. When ENABLE input high, output buffers disabled (OFF) without affecting information stored latches shift register. With ENABLE input low, outputs controlled state latches.
