MIC58P42
8-Bit Serial-Input Protected Latched Driver General Description Features The MIC58P42 serial-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 STROBE, CLOCK, SERIAL DATA INPUT, and
OUTPUT ENABLE functions. Similar to the MIC5842,
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
MIC58P42 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 can be
operated with a split supply, where the negative supply is
down to –20V and may be paralleled for higher load
current capability. 3.3 MHz Minimum Data-Input Rate
