UDN2580A 8-Channel Source Driver – Allegro Microsystems

This versatile family of integrated circuits will work with many combinations of logic- and load-voltage levels, meeting interface requirements beyond the capabilities of standard logic buffers. Series UDN2580A and A2580SLW source drivers can drive incandescent, LED, or vacuum fluorescent displays. Internal transient-suppression diodes permit the drivers to be used with inductive loads such as relays, solenoids, dc and stepping motors, and magnetic print hammers.
The Types UDN2580A and A2580SLW are high-current source drivers used to switch the ground ends of loads that are directly connected to a -50 V supply. Typical loads are telephone relays, PIN diodes, and LEDs. The UDN2585A and A2585SLW are drivers designed for applications requiring low output saturation voltages. Typical loads are low-voltage LEDs and incandescent displays. The eight non-Darlington, 25 V outputs will simultaneously sustain continuous load currents of -120 mA at ambient temperatures to +70°C.
The UDN2588A and A2588SLW have separate logic and driver supply lines. Their eight drivers can serve as an interface between positive logic (TTL, CMOS, PMOS) or negative logic (NMOS) and either negative or splitload supplies to -80 V. These drivers are packaged in plastic DlPs (suffix A) or surface-mountable wide-body Sols (suffix LW), and are rated for operation over the temperature range of -20°C to +85°C.
