5811 BiMOS 12-BIT SERIAL-INPUT, LATCHED SOURCE DRIVER
BiMOS 12-BIT SERIAL-INPUT, LATCHED SOURCE DRIVER
Designed primarily with vacuum-fluorescent displays, UCN5811A smart power BiMOS driver features low-output saturation voltages high output switching speed. These devices contain CMOS shift registers, data latches, control circuitry, bipolar high-speed sourcing outputs with DMOS active pull-down circuitry. high-speed shift register data latches allow direct interface with microprocessor-based systems. CMOS serial data output enables cascade connections applications requiring additional drive lines. UCN5811A features output ratings, allowing used many other peripheral power driver applications. used improved replacement SN75512B. Allegro devices require special power-up sequencing. UCN5811A been designed with BiMOS logic improved data entry rates. With supply, will typically operate above MHz. significantly higher speeds obtained. this device with require appropriate pull-up resistors ensure proper input logic high. This device supplied 20-pin plastic dual in-line package. operated over ambient temperature range -20°C +85°C. Copper lead frames output saturation voltages allow outputs operated continuously ambient temperatures 76°C.

CLOCK DATA STROBE BLANKING OUTN
Dwg. 12,649A
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 BLANKING input high during serial data entry. When BLANKING input high, output source drivers disabled (OFF); DMOS sink drivers information stored latches affected BLANKING input. With BLANKING input low, outputs controlled state their respective latches.
