MICREL SEMICONDUCTOR MIC5821YN

The MIC5821YN is a 8-bit serial-input Latched Driver. BiCMOS technology gives this family flexibility beyond the reach of standard logic buffers and power driver arrays. This device 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, this is identical. This device have greatly improved data-input rate. With a 5V logic supply they will typically operate faster than 5MHz. With a 12V supply significantly higher speeds are obtained. The CMOS inputs are compatible with standard CMOS, PMOS and NMOS logic levels.
