UDN2588A

The UDN2588A has the following features including TTL, CMOS, PMOS, NMOS Compatible;High Output Current Rating;Internal Transient Suppression;Efficient Input/Output Structure.

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 UDN2580A1LW 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, do and stepping motors, and magnetic print hammers.The Type UDN2580A and UDN2580LW are high-current source drivers used to switch the ground ends of loads that are directly connected to a -50 V supply. Selected devices (UDN2580A-1) may be operated to -80 V. Typical loads are telephone relays, PIN diodes,and LEDs.The UDN2585A and UDN2585LW 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.The UDN2588A has separate logic and driver supply lines. Its eight drivers can serve as an interface between positive logic (TTL, CMOS,PMOS) or negative logic (NMOS) and either negative or split-load supplies to -45 V. Selected devices (UDN2588A-1) may be operated to -65 V.These drivers are packaged in plastic DIPs (suffix A) or surface-mountable wide-body SOICs (suffix LW), and are rated for operation over the temperature range of -200C to +85.Note that the UDN2580/85A (dual in-line packages) and UND 2580/85LW (small-outline IC packages are electrically identical and share a common pin number assignment.

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/W and UDN2580A-1 is with negative referenced logic. The more common application of the UDN2585A/LW, UDN2588A, and UDN2588A-1 is with positive referenced logic supplies. The substrate must be tied to the mast negative point in the external circuit to maintain isolation between drivers and to provide for normal circuit operation.
