UCQ5810AF General Description

The UCQ5810AF has the following features including High-Speed Source Drivers;60 V Minimum Output Breakdown;Improved Replacements for TL4810B;Low Output Saturation Voltages;Low-Power CMOS Logic and Latches;To 3.3 MHz Data Input Rate;Active DMOS Pull-Downs.

The UCQ5810AF is furnished in an 18-pin dual in-line plastic package.Copper lead frames, reduced supply current requirements, and lower output saturation voltages allow all devices to source 25 mA from all outputs continuously, over the entire operating temperature range.The UCQ5810AF combines a 10-bit CMOS shift register and accompanying data latches, control circuitry, bipolar sourcing outputs with DMOS active pull-downs. 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 UCQ5810AF/EPF/LWF feature reduced supply requirements (active DMOS pull-downs) and lower saturation voltages when compared with the original UCQ5810A.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.Timing is representative of a 3.3 MHz clock. Higher speeds may be attainable with increased supply voltage; operation at high temperatures will reduce the specified maximum clock frequency.The information included herein is believed to be accurate and reliable.
