drivers permit the UCN5841A, UCN5841LW, and A5841SLW inte-
grated circuits to be used in a wide variety of peripheral power driver
applications. Each device has an eight-bit CMOS shift register and
CMOS control circuitry, eight CMOS data latches, and eight bipolar
current-sinking Darlington output drivers. The 500 mA npn Darlington
outputs, with integral transient-suppression diodes, are suitable for use
with relays, solenoids, and other inductive loads. All drivers can be
operated with a split supply where the negative supply is up to -20 V.
BiMOS circuits. With a 5 V logic supply, they will typically operate at
better than 5 MHz. With a 12 V supply, significantly higher speeds are
obtained. The CMOS inputs are compatible with standard CMOS and
NMOS logic levels. TTL circuits may require the use of appropriate
pull-up resistors. By using the serial data output, drivers can be
cascaded for interface applications requiring additional drive lines.
DIP; the UCN5841LW devices are in an 18-lead surface-mountable
wide-body SOIC package; the A5841SLW devices are provided in a
20-lead wide-body SOIC package with improved thermal characteris-
tics.

‘SLW’ to ‘ELW’, or change the prefix from ‘UCN’ to ‘UCQ’.
Always order by complete part number, e.g., A5841SLW .
