MIC58P01
8-Bit Parallel-Input Protected Latched
Driver
General Description
The MIC58P01 parallel-input latched driver is a high-
voltage (80V), high-current (500mA) integrated circuit
comprised of 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. Similar to the MIC5801,
additional protection circuitry supplied on this device
includes thermal shutdown, under voltage lockout (UVLO),
and overcurrent shutdown.
The bipolar/CMOS combination provides an extremely
low-power latch with maximum interface flexibility. The
MIC58P01 has open-collector outputs capable of sinking
500 mA and integral diodes for inductive load transient
suppression with a minimum output breakdown voltage
rating of 80V (50V sustaining). The drivers may be
paralleled for higher load current capability.
With a 5V logic supply, the MIC58P01 will typically operate
at better than 5MHz. With a 12V logic supply, significantly
higher speeds are obtained. The CMOS inputs are
compatible with standard CMOS, PMOS, and NMOS
circuits. TTL circuits may require pull-up resistors.
Each of these eight outputs has an independent
overcurrent shutdown of 500mA. Upon current shutdown,
the affected channel will turn OFF until V
DD
is cycled or the
ENABLE/RESET pin is pulsed high. Current pulses less
than 2μs will not activate current shutdown. Temperatures
above 165°C will shut down all outputs. The UVLO circuit
disables the outputs at low V
DD
; hysteresis of 0.5V is
provided.

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”.
6. Under-Voltage Lockout is guaranteed to release device at no more than 4.5V, and disable the device at no less than 3.0V.

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. If current shutdown is activated, the OUTPUT ENABLE must be pulsed high to
restore operation. Over temperature faults are not latched and require no reset pulse.
