MIC5800/5801
4/8-Bit Parallel-Input Latched Drivers General Description Features The MIC5800/5801 latched drivers are high-voltage, highcurrent integrated circuits comprised of four or 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. The bipolar/MOS combination provides an extremely lowpower latch with maximum interface flexibility. MIC5800
contains four latched drivers; MIC5801 contains eight
latched drivers. 4.4MHz Minimum Data Input Rate
High-Voltage, Current Sink Outputs
Output Transient Protection
CMOS, PMOS, NMOS, and TTL Compatible Inputs
Internal Pull-Down Resistors
Low-Power CMOS Latches Data input rates are greatly improved in these devices.
With a 5V supply, they will typically operate at better than
5MHz. With a 12V supply, significantly higher speeds are
obtained. The CMOS inputs are compatible with standard
CMOS, PMOS, and NMOS circuits. TTL or DTL circuits
may require the use of appropriate pull-up resistors. The
bipolar outputs are suitable for use with relays, solenoids,
stepping motors, LED or incandescent displays, and other
high-power loads. Both units have open-collector outputs
and integral diodes for inductive load transient
suppression. The output transistors are capable of sinking
500mA and will sustain at least 50V in the OFF state. …
