Description of Blocks - continued

7.

EN

A “High” input of 2.3V or higher to EN turns ON the VTT output. A “Low” input of 0.8V or less, on the other hand, turns

VTT to a Hi-

Z state. With a “Low” EN input, however, the VREF output remains ON, provided that sufficient VCC and

VDDQ voltages have been established.

(Note 2) Should not exceed Pd.

(Note 3) Instantaneous surge voltage, back electromotive force and voltage under less than 10% duty cycle.

(Note 4) Derate by 4.48mW/°C for Ta over 25°C (With no heat sink).

(Note 5) Derate by 5.52mW/°C for Ta over 25°C (When mounted on a board 70mm x 70mm x 1.6mm Glass-epoxyPCB).

(Note 6) Derate by 5.04mW/°C for Ta over 25°C (when mounted on a 70mm x 70mm x 1.6mm glass-epoxy board, 1-layer)

On less than 0.2% (percentage occupied by copper foil.

(Note 7) Derate by 10.8mW/°C for

Ta over 25°C (when mounted on a 70mm x 70mm x 1.6mm glass-epoxy board, 1-layer)

On less than 7.0% (percentage occupied by copper foil.

(Note 8) Derate by 14.0mW/°C for Ta over 25°C (when mounted on a 70mm x 70mm x 1.6mm glass-epoxy board, 1-layer)

On less than 65.0% (percentage occupied by copper foil.

Caution: Operating the IC over the absolute maximum ratings may damage the IC. In addition, it is impossible to predict all destructive situations such as

short-circuit modes, open circuit modes, etc. Therefore, it is important to consider circuit protection measures, like adding a fuse, in case the IC is operated in a

special mode exceeding the absolute maximum ratings.
