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 lock out (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 shu tdown, the affected channel will turn off until v dd 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 output s at low v dd ; hysteresis of 0.5v is provided. datasheets and support documentation are available on micrels web site at : www.micrel.com . features ? 4.4mhz minimum data input rate ? high - voltage, high - current outputs ? per - output overcurrent shutdown (500ma typical) ? under voltage lockout ? thermal shutdown ? output transient protection diodes ? cmos, pmos, nmos, and ttl compatible inputs ? internal pull - down resistors ? low - power cmos latches typical application micrel inc. ? 2180 fortune drive ? san jose, ca 95131 ? usa ? tel +1 (408) 944-0800 ? fax + 1 (408) 474-1000 ? http://www.micrel.com june 5, 2015 revision 2.0 downloaded from: http:///
