NOTES
1. NC = NO CONNECT.
2. THE EXPOSED PAD IS INTERNALLY CONNECTED TO AGND. THIS
CONNECTION IS NOT REQUIRED TO MEET THE ELECTRICAL
PERFORMANCES; HOWEVER, FOR INCREASED RELIABILITY OF
THE SOLDER JOINTS, IT IS RECOMMENDED THAT THE PAD BE
SOLDERED TO THE ANALOG GROUND OF THE SYSTEM.

D0/OB/2C
DI/O
When MODE = 0 (18-bit interface mode), this pin is Bit 0 of the parallel port data output bus and the
data coding is straight binary. In all other modes, this pin allows choice of straight binary/binary twos
complement. When OB/2C is HIGH, the digital output is straight binary; when LOW, the MSB is
inverted, resulting in a twos complement output from its internal shift register.

NC
No Connect.
8
D1/A0
DI/O
When MODE = 0 (18-bit interface mode), this pin is Bit 1 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.
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), 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.
