MIC5800/5801
4/8-Bit Parallel-Input Latched Drivers
General Description
Features
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.
• 4.4MHz Minimum Data Input Rate
• High-Voltage, Current Sink Outputs
• Output Transient Protection
• CMOS, PMOS, NMOS, and TTL Compatible Inputs
• Internal Pull-Down Resistors
The bipolar/MOS combination provides an extremely low-
power latch with maximum interface flexibility. MIC5800
contains four latched drivers; MIC5801 contains eight
latched drivers.
• Low-Power CMOS Latches
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.

Notes:
1. Exceeding the absolute maximum ratings may damage the device.
2. The device is not guaranteed to function outside its operating ratings.
3. Micrel CMOS devices have input-static protection but are susceptible to damage when exposed to extremely high static electrical charges.
4. Specification for packaged product only.
5. Operation of these devices with standard TTL or DTL may require the use of appropriate pull-up resistors to insure a minimum logic “1”.

Truth Table
Information present at an input is transferred to its latch
when the STROBE is high. A high CLEAR input will set all
OUTN
INN
Strobe
Clear
/OE
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 respective latches.
