UCN5890LW, UCN5891A, and UCN5891LW are BiMOS II serial-input,

latched source (high-side) drivers. The octal, high-current smart-power ICs

merge an 8-bit CMOS shift register, associated CMOS latches, and CMOS

control logic (strobe and output enable) with sourcing power Darlington

outputs. Typical applications include multiplexed LED and incandescent

displays, relays, solenoids, and similar peripheral loads to a maximum of

-500 mA per output.

equivalent. The UCN5890A/LW are rated for operation with load supply

voltages of 20 V to 80 V and a minimum output sustaining voltage of 50 V.

The UCN5891A/LW are optimized for operation with supply voltages of 5 V

to 50 V (35 V sustaining).

circuits. With a 5 V supply, they will operate to at least 3.3 MHz. At 12 V,

higher speeds are possible. The CMOS inputs are compatible with standard

CMOS and NMOS logic levels. TTL circuits may require the use of appropri-

ate pull-up resistors to ensure a proper input-logic high. A CMOS serial data

output, allows cascading these devices in multiple drive-line applications

required by many dot matrix, alphanumeric, and bar graph displays.

with copper lead frame for enhanced package power dissipation characteris-

tics. Suffix ‘LW’ devices are supplied in a standard wide-body SOIC package

for surface-mount applications. Similar driver, featuring reduced output

saturation voltage, are the UCN5895A and A5895SLW. Complementary,

8-bit serial-input, latched sink drivers are the Series UCN5820A.
