www.DataSheet4U.com Data Sheet 26185.112B A6821 DABiC-5 8-Bit Serial Input Latched Sink Drivers A merged combination of bipolar and MOS technology gives these devices an interface ﬂexibility beyond the reach of standard logic buffers and power driver arrays. Typical applications include driving multiplexed LED displays or incandescent lamps. The A6821 has an eight-bit CMOS shift register and CMOS control circuitry, eight CMOS data latches, and eight bipolar current-sinking Darlington output dr.
