Frequently applied in non-impact printer systems, the UCN5890A,
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.
Except for output voltage ratings, these smart high-side driver ICs are
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).
BiMOS II devices have higher data-input rates than the original BiMOS
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.
Suffix ‘A’ devices are supplied in a standard dual in-line plastic package
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.

Caution: CMOS devices have input static
protection, but are susceptible to damage when
exposed to extremely high static electrical
charges.
Always order by complete part number, e.g., UCN5891LW .

5891
Note the suffix ‘A’ devices (DIP) and the suffix
‘LW’ devices (SOIC) are electrically identical and
share a common terminal number assignment.
