UCN5891A Datasheet PDF - Allegro MicroSystems

Frequently applied in non-impact printer systems, the UCN5890A, UCN5890LW, UCN5891A, and UCN5891LW are BiMOS II serial-input, latched source (high-side) drivers. The octal, high-current smart-power ICs merge an 8-bit CMOS shift register, associated CMOS latches, and CMOS control logic (strobe and output enable) with sourcing power Darlington outputs. Typical applications include multiplexed LED and incandescent displays, relays, solenoids, and similar peripheral loads to a maximum of -500 mA per output.

FEATURES
■ 50 V or 80 V Source Outputs
■ Output Current to -500 mA
■ Output Transient-Suppression Diodes
■ To 3.3 MHz Data-lnput Rate
■ Low-Power CMOS Logic and Latches
