BiMOS II 8-BIT SERIAL-INPUT,
LATCHED DRIVERS
The merging of low-power CMOS logic and bipolar output power
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 II devices have higher data-input rates than the earlier
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.

The UCN5841A devices are furnished in a standard 18-pin plastic
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.
Note that the UCN5841A (dual in-line package) and
UCN5841LW (small-outline IC package) are electrically
identical and share a common terminal number assignment.
The A5841SLW and UCN5841LW drivers are also available for
operation to a temperature of -40°C. To order, change the suffix from
‘SLW’ to ‘ELW’, or change the prefix from ‘UCN’ to ‘UCQ’.

TYPICAL OUTPUT DRIVER
Serial Data present at the input is transferred to the shift register
on the logic “0” to logic “1” transition of the CLOCK input pulse. On
succeeding CLOCK pulses, the registers shift data information towards
the SERIAL DATA OUTPUT. The SERIAL DATA must appear at the
input prior to the rising edge of the CLOCK input waveform.
K
Information present at any register is transferred to its respective
latch when the STROBE is high (serial-to-parallel conversion). The
latches will continue to accept new data as long as the STROBE is held
high. Applications where the latches are bypassed (STROBE tied high)
will require that the ENABLE input be high during serial data entry.
OUT
V
EE
When the ENABLE input is high, all of the output buffers are
disabled (OFF) without affecting the information stored in the latches or
shift register. With the ENABLE input low, the outputs are controlled by
the state of the latches.
