EDS6416AHTA, EDS6416CHTA
Electrical Specifications
• All voltages are referenced to VSS (GND).
• After power up, execute power up sequence and initialization sequence before proper device operation is achieved
(refer to the Power up sequence).

Caution
Exposing the device to stress above those listed in Absolute Maximum Ratings could cause
permanent damage. The device is not meant to be operated under conditions outside the limits
described in the operational section of this specification. Exposure to Absolute Maximum Rating
conditions for extended periods may affect device reliability.

Notes: 1. The supply voltage with all VDD and VDDQ pins must be on the same level.
2. The supply voltage with all VSS and VSSQ pins must be on the same level.
3. VIH (max.) = VDD + 1.5V (pulse width ≤ 5ns).
4. VIL (min.) = VSS – 1.5V (pulse width ≤ 5ns).
