AT27C4096

Notes:

1. X can be VIL or VIH.

2. Refer to the Programming characteristics.

3. V

H = 12.0 ± 0.5V.

4. Two identifier words 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 word and high (VIH) to select the Device Code word.

5. Standby V

CC current (ISB) is specified with VPP = VCC. VCC > VPP will cause a slight increase in ISB.

Notes:

1. VCC must be applied simultaneously or before VPP, and removed simultaneously or after VPP.

2. VPP may be connected directly to VCC, except during programming. The supply current would then be the sum of ICC and IPP.
