ucn5890 Allegro MicroSystems, Inc., ucn5890 Datasheet - Page 3

• Manufacturer Part Number: ucn5890
• Description: Bimos Ii 8-bit Serial-input, Latched Source Drivers
• Manufacturer: Allegro MicroSystems, Inc.

NOTES: Turn-off delay is influenced by load conditions. Systems applications well below the specified output loading may require
* Operation at a clock frequency greater than the specified minimum value is possible but not warranteed.
