The merging of low-power CMOS logic and bipolar output power drivers permit the UCN5841/42A, UCN5841/42LW, and A5841/42SLW integrated circuits to be used in a wide variety of peripheral power driver applications. Each device has an eight-bit CMOS shift register and CMOS control circuitry, eight CMOS data latches, and eight bipolar current-sinking Darlington output drivers. The 500 mA npn Darlington outputs, with integral transient-suppression diodes, are suitable for use with relays, solenoids, and other inductive loads. Except for packaging and the maximum driver output voltage ratings, the UCN5841A, UCN5841LW, A5841SLW, UCN5842A, UCN5842LW, and A5842SLW are identical. All package variations of the 5842 offer premium performance with a minimum output-breakdown voltage rating of 80 V (50 V sustaining). All drivers can be operated with a split supply where the negative supply is up to -20 V.
