8-Bit Serial-Input Latched Drivers Final Information
General Description
Bi
CMOS 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.
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 o...
