Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. No terminal voltage may exceed Vcc by +0.5V unless otherwise noted. 2. Inputs and Vcc terminals only. 3. Output and I/O terminals only. Pin Names Description OEA, OEB 3-State Output Enable Inputs (Active LOW) Dxx Inputs Oxx Outputs PIN DESCRIPTION Symbol Parameter(1) Conditions Typ. Max.
