Each device has an eight-bit CMOS shift register and CMOS control circuitry, eight CMOS data latches, and eight bipolarcurrent-sinking Darlington output drivers.
This paper introduces a stable amplitude bipolarcurrent source. It was designed basing on the principle of automatic control. This circuit is suitable for continuous casting slag detection.
