AT27C080

Notes:

1. X can be VIL or VIH.

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 (VIL), except A9 which is set to VH and A0 which is toggled

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

Note:

1. V

CC must be applied simultaneously or before OE/ VPP, and removed simultaneously or after OE/VPP.
