february 2005 1 mic5821/5822 micrel, inc. mic5821/5822 mic5821/5822 8-bit serial-input latched drivers final information 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 C20v. 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. features ?3 .3 mhz minimum data-input rate ? cmos, pmos, nmos, ttl compatible ?i nternal pull-down or pull-up resistors ? low-power cmos logic and latches ?h igh-voltage current-sink outputs ?s ingle or split supply operation 8-bit serial-parallel shift register 5 serial data out clk 1 2 3 serial data in v ss 9 v dd strobe output enable (active low) bipolar mos latches out 8 10 11 12 13 14 15 16 out 7 out 6 out 5 out 4 out 3 out 2 out 1 4 6 7 sub gnd v ee 8 functional diagram pin configuration 1 2 3 4 5 6 7 12 11 10 9 v dd 1 out 2 out 3 out 4 out clock serial data out ss v 8 13 14 15 5 out 6 out 7 out 8 out serial data in strobe output enable sub v ee 16 latches shift register (plastic dip) micrel, inc. ? 2180 fortune drive ? san ose, ca 95131 ? usa ? tel + 1 (408) 944-0800 ? fax + 1 (408) 474-1000 ? http://www.mic rel.com ordering information part number standard pb-free temp range package mic5821bn MIC5821YN C40 c to +85 c 16-pin plastic dip mic5822bn mic5822yn C40 c to +85 c 16-pin plastic dip
