Decoded DAC Register
O
i
=
A
where
A
is the decimal value of the decoded address bits A3,
A2, A1, A0 (LSB).
Address,
CS
, R/
W
and data inputs should be stable prior to acti-
vation of the active low
EN
input. Input registers are transpar-
ent when
EN
is low. When
EN
returns high, data is latched into
the decoded input register. When the load strobe
LD
and
EN
pins are active low, all input register data is transferred to the
DAC registers. T he DAC registers are transparent while they
are enabled.
