MIC5821/5822 Micrel, Inc. MIC5821/5822 8-Bit Serial-Input Latched Drivers Final Information General Description Features BiCMOS technology gives the MIC5821/5822 family flexibil- 3.3 MHz Minimum Data-Input Rate ity beyond the reach of standard logic buffers and power CMOS, PMOS, NMOS, TTL Compatible driver arrays. These devices each have an eight-bit CMOS Internal Pull-Down or Pull-Up Resistors shift register, CMOS control circuitry, eight CMOS data Low-Power CMOS Logic and Latches latches, and eight bipolar current-sink Darlington output High-Voltage Current-Sink Outputs drivers. The 500mA outputs are suitable for use with incan- Single or Split Supply Operation 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.
