MIC5800/5801
4/8-Bit Parallel-Input Latched Drivers
General Description
The MIC5800/5801 latched drivers are high-voltage, high-
current integrated circuits comprised of four or eight CMOS
data latches, a bipolar Darlington transistor driver for each
latch, and CMOS control circuitry for the common CLEAR,
STROBE, and OUTPUT ENABLE functions.
The bipolar/MOS combination provides an extremely low-
power latch with maximum interface flexibility. MIC5800
contains four latched drivers; MIC5801 contains eight latched
drivers.
Data input rates are greatly improved in these devices. With
a 5V supply, they will typically operate at better than 5MHz.
With a 12V supply, significantly higher speeds are obtained.
The CMOS inputs are compatible with standard CMOS,
PMOS, and NMOS circuits. TTL or DTL circuits may require
the use of appropriate pull-up resistors. The bipolar outputs
are suitable for use with relays, solenoids, stepping motors,
LED or incandescent displays, and other high-power loads.
Both units have open-collector outputs and integral diodes for
inductive load transient suppression. The output transistors
are capable of sinking 500mA and will sustain at least 50V in
the OFF state. Because of limitations on package power
dissipation, the simultaneous operation of all drivers at maxi-
mum rated current can only be accomplished by a reduction
in duty cycle. Outputs may be paralleled for higher load
current capability.

Information present at an input is transferred to its latch when
the STROBE is high. A high CLEAR input will set all latches
to the output OFF condition regardless of the data or
STROBE input levels. A high OUTPUT ENABLE will set all
outputs to the off condition, regardless of any other input
conditions. When the OUTPUT ENABLE is low, the outputs
depend on the state of their respective latches.
