does not require microprocessor WAIT states. A READ
operation simultaneously initiates a conversion and
reads the previous conversion result.
Interface Mode 0
Figure 5 shows the timing diagram for Mode 0 opera-
tion. This is used with microprocessors that have WAIT
state capability, whereby a READ instruction is extend-
ed to accommodate slow-memory devices. Taking CS
and RD low latches the analog multiplexer address and
starts a conversion. Data outputs DB0–DB7 remain in
the high-impedance condition until the conversion is
complete.
There are two status outputs: Interrupt (INT) and Ready
(RDY). RDY, an open-drain output (no internal pull-up
device), is connected to the processor’s READY/WAIT
input. RDY goes low on the falling edge of CS and goes
high impedance at the end of the conversion, when the
conversion result appears on the data outputs. If the RDY
output is not required, its external pull-up resistor can be
omitted. INT goes low when the conversion is complete
and returns high on the rising edge of CS or RD.
Interface Mode 1
Mode 1 is designed for applications where the micro-
processor is not forced into a WAIT state. Taking CS
and RD low latches the multiplexer address and starts
a conversion (Figure 6). Data from the previous conver-
sion is immediately read from the outputs (DB0–DB7).
INT goes high at the rising edge of CS or RD and goes
low at the end of the conversion. A second READ oper-
ation is required to read the result of this conversion.
The second READ latches a new multiplexer address
and starts another conversion. A delay of 2.5µs must
be allowed between READ operations. RDY goes low
on the falling edge of CS and goes high impedance at
the rising edge of CS. If RDY is not needed, its external
pull-up resistor can be omitted.
