MIC5841/5842
8-Bit Serial-Input Latched Drivers General Description
Using BiCMOS technology, the MIC5841/5842 integrated
circuits were fabricated to be used in a wide variety of
peripheral power driver applications. The devices each
have an eight-bit CMOS shift register, CMOS control
circuitry, eight CMOS data latches, and eight bipolar
current-sink Darlington output drivers.
These two devices differ only in maximum voltage ratings.
The MIC5842 offers premium performance 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.
The 500mA outputs, with integral transient-suppression
diodes, are suitable for use with lamps, relays, solenoids
and other inductive loads.
These devices have improved speed characteristics. With
a 5V logic supply, they will typically operate faster than
5 MHz. With a 12V supply, significantly higher speeds are
obtained. The CMOS inputs are compatible with standard
CMOS, PMOS, and NMOS logic levels. TTL or DTL
circuits may require the use of appropriate pull-up
resistors. By using the serial data output, the drivers can …
