DS75494 Hex Digit Driver General Description Features The DS75494 is a hex digit driver designed to interface between most MOS devices and common cathodes configured LED’s with a low output voltage at high operating currents. The enable input disables all the outputs when taken high.

They are not meant to imply that the devices should be operated at these limits. The table of ‘‘Electrical Characteristics’’ provides conditions for actual device operation. Note 2: Unless otherwise specified min/max limits apply across the 0§ C to a 70§ C range for the DS75494. Note 3: All currents into device pins shown as positive, out of device pins as negative, all voltages referenced to ground unless otherwise noted. All values shown as max or min on absolute value basis.
