Functional Description
The HT23C256 has two modes, namely data
read mode and standby mode, controlled by
CE /CE /OE 1/OE 1 and OE /OE /NC inputs.
Standby mode
The HT23C256 has lower current consumption,
controlled by the chip enable input (CE/CE).
When a low/high level is applied to the CE/CE
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/OE /OE 1)
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.
