MIC5821/5822
8-Bit Serial-Input Latched Drivers
General Description
BiCMOS technology gives the MIC5821/5822 family flexibil-
ity beyond the reach of standard logic buffers and power
driver arrays. These devices each have an eight-bit CMOS
shift register, CMOS control circuitry, eight CMOS data
latches, and eight bipolar current-sink Darlington output
drivers. The 500mA outputs are suitable for use with incan-
descent bulbs and other moderate to high current loads. The
drivers can be operated with a split supply where the negative
supply is down to –20V. Except for maximum driver output
voltage ratings, the MIC5821 and MIC5822 are identical.
These devices have greatly improved data-input rates. 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 and DTL circuits
may require the use of appropriate pull-up resistors. By using
the serial data output, the drivers can be cascaded for
interface applications requiring additional drive lines.
