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 mag-
netic print hammers.
