8-Bit Parallel-Input Protected Latched Driver
Final Information
General Description
Features
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 lowpower 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.

Ordering Information
Part Number
Each of these eight outputs has an independent overcurrent
shutdown of 500mA. Upon current shutdown, the affected
channel will turn OFF until VDD 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 VDD; hysteresis of 0.5V is provided.

NOTE 1:
NOTE 2:
NOTE 3:
Operation of these devices with standard TTL or DTL may require the use of appropriate pull-up resistors to insure a minimum logic “1”.
Under-Voltage Lockout is guaranteed to release device at no more than 4.5V, and disable the device at no less than 3.0V.
Specification for packaged product only.
Truth Table
Output
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.
