Identification Code

A0 = V_IHor V_IL

A1 - A18 = V_IL

Notes: 1. X can be V_ILor V_IH.

2. Refer to Programming Characteristics

3. V_H= 12.0 ± 0.5V.

4. Two identifier bytes may be selected. All Ai inputs are held low (V_IL), except A9 which is set to V_Hand A0 which is toggled

low (V_IL) to select the Manufacturer’s Identification byte and high (V_IH) to select the Device Code byte.

Absolute Maximum Ratings*

*NOTICE:

Stresses beyond those listed under “Absolute

Maximum Ratings” may cause permanent dam-

age to the device. This is a stress rating only and

functional operation of the device at these or any

other conditions beyond those indicated in the

operational sections of this specification is not

implied. Exposure to absolute maximum rating

conditions for extended periods may affect

device reliability.
