MIC59P50
8-Bit Parallel-Input Protected
Latched Driver General Description Features The MIC59P50 parallel-input latched driver is a highvoltage (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, undervoltage lockout (UVLO),
and overcurrent shutdown. The bipolar/MOS combination provides an extremely lowpower latch with maximum interface flexibility. The
MIC59P50 has open-collector outputs capable of sinking
500mA and integral diodes for inductive load transient
suppression with a minimum output breakdown voltage
rating of 80V above VEE (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. 4.4MHz minimum data input rate
