General Description
The MIC5891 latched driver is a high-voltage,
high-current integrated circuit comprised of eight
CMOS data latches, CMOS control circuitry for the
common STROBE and OUTPUT ENABLE, and bipolar
Darlington transistor drivers for each latch.
Bipolar/MOS construction provides extremely low
power latches with maximum interface flexibility.
The MIC5891 will typically operate at 5 MHz with a 5V
logic supply.
The CMOS inputs are compatible with standard
CMOS, PMOS, and NMOS logic levels. TTL circuits
may be used with appropriate pull-up resistors to
ensure a proper logic-high input.
A CMOS serial data output allows additional drivers to
be cascaded when more than 8 bits are required.
The MIC5891 has open-emitter outputs with
suppression diodes for protection against inductive
load transients. The output transistors are capable of
sourcing 500 mA and will sustain at least 35V in the
on-state.
Simultaneous operation of all drivers at maximum rated
current requires a reduction in duty cycle due to
package power limitations. Outputs may be paralleled
for higher load current capability.
The MIC5891 is available in a 16-pin plastic DIP
package (N) and 16-pin wide SOIC package (WM).

APPLICATION INFORMATION
Serial data present at the input is transferred into the
shift register on the rising edge of the CLOCK input
pulse. Additional CLOCK pulses 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.
The 8 bits present in the shift register are transferred to
the respective latches 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. Most applications where the latching feature is
not used (STROBE tied high) require the OUTPUT
ENABLE input to be high during serial data entry.
Outputs are active (controlled by the latch state) when
the OUTPUT ENABLE is low. All outputs are low
(disabled) when the OUTPUT ENABLE is high.
OUTPUT ENABLE does not affect the data in the shift
register or latch.
