NOTES
1+ symbol means positive edge of control input line.
2– symbol means negative edge of control input line.
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. The DAC registers are transparent while they
are enabled.
