Unless otherwise noted, VCC = 1.2V to 5.5V and specifications are over the operating temperature range of – 40°C to +85°C.

All voltages are referenced to ground.

Notes 1. The tF value is for reference in defining values for tRPD and should not be considered a requirement for proper operation or use.
