4/8-Bit Parallel-Input Latched Drivers
Final Information
General Description
The MIC5800/5801 latched drivers are high-voltage, high-
current 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 low-
power latch with maximum interface flexibility. MIC5800
contains four latched drivers; MIC5801 contains eight latched
drivers.
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
Ordering Information
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. Because of limitations on package
power dissipation, the simultaneous operation of all drivers at
maximum rated current can only be accomplished by a
reduction in duty cycle. Outputs may be paralleled for higher
load current capability.
