drivers permit the UCN5841/42A, UCN5841/42LW, and A5841/42SLW
integrated 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. Except for packaging
and the maximum driver output voltage ratings, the UCN5841A,
UCN5841LW, A5841SLW, UCN5842A, UCN5842LW, and A5842SLW
are identical. All package variations of the 5842 offer premium perfor-
mance with a minimum output-breakdown voltage rating of 80 V (50 V
sustaining). 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 UCN584xLW devices are in an 18-lead surface-mountable
wide-body SOIC package; the A584xSLW devices are provided in a 20-
lead wide-body SOIC package with improved thermal characteristics.

‘SLW’ to ‘ELW’, or change the prefix from ‘UCN’ to ‘UCQ’.
