HT23C010

Functional Description

The HT23C010 has two modes, namely data

read mode and standby mode, controlled by

CE/CE/OE1/OE1 and OE/OE/NC inputs.

• Standby mode

The HT23C010 offers lower current consump-

tion, controlled by the chip enable input

(CE/CE). When a low/high level is applied to the

CE/CEB input regardless of the output enable

(OE/OE/NC) states the chip will enter the

standby mode.

• Data read mode

When both the chip enable (CE/CE/OE1/OE1)

and the output enable (OE/OE/NC) are active,

the chip is in data read mode. Otherwise,

active CE/CE and inactive OE/OE/NC result

in deselect mode. The output will remain in

Hi-Z state.
