GENERAL DESCRIPTION
BiCMOS technology gives the MIC5821/5822 family flexibility 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 incandescent 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. 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 o
