Description
9
D2/A1
DI/O
When MODE = 0 or 1 (18-bit or 16-bit interface mode), this pin is Bit 2 of the parallel port data output
bus. In all other modes, this input pin controls the form in which data is output, as shown in Table 7.
10
D3
DO
In all modes except MODE = 3, this output is used as Bit 3 of the parallel port data output bus. This pin is
always an output, regardless of the interface mode.
11, 12
D[4:5]or
DIVSCLK[0:1]
DI/O
In all modes except MODE = 3, these pins are Bit 4 and Bit 5 of the parallel port data output bus.
When MODE = 3 (serial mode), when EXT/INT is LOW and RDC/SDIN is LOW (serial master read after
convert), these inputs, part of the serial port, are used to slow down, if desired, the internal serial clock
that clocks the data output. In other serial modes, these pins are not used.
13
D6 or
EXT/INT
DI/O
In all modes except MODE = 3, this output is used as Bit 6 of the parallel port data output bus.
When MODE = 3 (serial mode), this input, part of the serial port, is used as a digital select input for
choosing the internal data clock or an external data clock. With EXT/INT tied LOW, the internal clock is
selected on the SCLK output. With EXT/INT set to a logic HIGH, output data is synchronized to an
external clock signal connected to the SCLK input.
14
D7 or
INVSYNC
DI/O
In all modes except MODE = 3, this output is used as Bit 7 of the parallel port data output bus.
When MODE = 3 (serial mode), this input, part of the serial port, is used to select the active state of the
SYNC signal. When LOW, SYNC is active HIGH. When HIGH, SYNC is active LOW.
15
D8 or
INVSCLK
DI/O
In all modes except MODE = 3, this output is used as Bit 8 of the parallel port data output bus.
When MODE = 3 (serial mode), this input, part of the serial port, is used to invert the SCLK signal. It is
active in both master and slave mode.
16
D9 or
RDC/SDIN
DI/O
In all modes except MODE = 3, this output is used as Bit 9 of the parallel port data output bus.
When MODE = 3 (serial mode), this input, part of the serial port, is used as either an external data input
or a read mode selection input depending on the state of EXT/INT. When EXT/ INT is HIGH, RDC/SDIN
could be used as a data input to daisy-chain the conversion results from two or more ADCs onto a single
SDOUT line. The digital data level on SDIN is output on SDOUT with a delay of 18 SCLK periods after the
initiation of the read sequence. When EXT/INT is LOW, RDC/SDIN is used to select the read mode. When
RDC/SDIN is HIGH, the data is output on SDOUT during conversion. When RDC/SDIN is LOW, the data
can be output on SDOUT only when the conversion is complete.
17
OGND
P
Input/Output Interface Digital Power Ground.
18
OVDD
P
Output Interface Digital Power. Nominally at the same supply as the host interface (5 V or 3 V). Should
not exceed DVDD by more than 0.3 V.
19
DVDD
P
Digital Power. Nominally at 5 V.
20
DGND
P
Digital Power Ground.
21
D10 or
SDOUT
DO
In all modes except MODE = 3, this output is used as Bit 10 of the parallel port data output bus.
When MODE = 3 (serial mode), this output, part of the serial port, is used as a serial data output
synchronized to SCLK. Conversion results are stored in an on-chip register. The AD7674 provides the
conversion result, MSB first, from its internal shift register. The data format is determined by the logic
level of OB/2C. In serial mode when EXT/INT is LOW, SDOUT is valid on both edges of SCLK. In serial
mode when EXT/INT is HIGH and INVSCLK is LOW, SDOUT is updated on the SCLK rising edge and is
valid on the next falling edge; if INVSCLK is HIGH, SDOUT is updated on the SCLK falling edge and is
valid on the next rising edge.
22
D11 or
SCLK
DI/O
In all modes except MODE = 3, this output is used as Bit 11 of the parallel port data output bus.
When MODE = 3 (serial mode), this pin, part of the serial port, is used as a serial data clock input or
output, dependent upon the logic state of the EXT/INT pin. The active edge where the data SDOUT is
updated depends upon the logic state of the INVSCLK pin.
23
D12 or
SYNC
DO
In all modes except MODE = 3, this output is used as Bit 12 of the parallel port data output bus.
When MODE = 3 (serial mode), this output, part of the serial port, is used as a digital output frame
synchronization for use with the internal data clock (EXT/INT = Logic LOW). When a read sequence is
initiated and INVSYNC is LOW, SYNC is driven HIGH and remains HIGH while the SDOUT output is valid.
When a read sequence is initiated and INVSYNC is HIGH, SYNC is driven LOW and remains LOW while
SDOUT output is valid.
24
D13 or
RDERROR
DO
In all modes except MODE = 3, this output is used as Bit 13 of the parallel port data output bus.
In MODE = 3 (serial mode) and when EXT/ INT is HIGH, this output, part of the serial port, is used as an
incomplete read error flag. In slave mode, when a data read is started and not complete when the
following conversion is complete, the current data is lost and RDERROR is pulsed high.
25–28
D[14:17]
DO
Bit 14 to Bit 17 of the Parallel Port Data Output Bus. These pins are always outputs regardless of the
interface mode.
