MIC5800/5801
4/8-Bit Parallel-Input Latched Drivers
General Descr i ption
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 maximum 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 /OE will set all outputs to
the off condition, regardless of any other input conditions.
When the /OE is low, the outputs depend on the state of
their respectiv e l atches.
