MIC5891
Features
• High-voltage, high-current outputs
• Output transient protection diodes
• CMOS-, PMOS-, NMOS-, and TTL-compatible inputs
• 5MHz typical data input rate
• Low-power CMOS latches
Applications
• Alphanumeric and bar graph displays
• LED and incandescent displays
• Relay and solenoid drivers
• Other high-power loads
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 OUT-
PUT 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 5MHz 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 500mA 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).
