MICHEL MIC58P01 8-Bit Parallel-input Protected Latched Driver General Description The MICS8P01 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, ancl 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 MIC58P014 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 rnay 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 wil! turn OFF until V,, is cycled or the ENABLE/ RESET pin is pulsed high. Current pulses less than 2s will not activate current shutdown. Temperatures above 165C will shut down all outputs. The UVLO circuit disables the outputs at low V,,; hysteresis of 0.5V is provided.

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 ail latches tothe 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. |f 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. 1997 7-19MIC58P01 Micrel CLEAR | ae STROBE | | | male cal -o laye. tale ofa OUTPUT ae fC TL fr wt G t+ G INN | | > Die Ee ~> EM OUTy | | | Timing Conditions (T, = +25C, Logic Levels are Voo and Ground, V,, = 5V) A.
