8-CHANNEL SOURCE DRIVERS

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.

ABSOLUTE MAXIMUM RATINGS

See next page.

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 SOlCs (suffix LW), and are rated for operation over the
temperature range of -20°C to +85°C.

For simplification, these devices are characterized on the following pages with

specific voltages for inputs, logic supply (VS), load supply (VEE), and collector
supply (VCC). Typical use of the UDN2580A and A2580SLW is with negative­referenced logic. The more common application of the UDN2585A, A2585SLW,
UDN2588A and A2588SLW are with positive-referenced logic supplies. In
application, the devices are capable of operation over a wide range of logic and
supply voltage levels:
