Digital I/O Bit 4 of 14-Bit Parallel Data Bus. High impedance when

RD = 1 or CS = 1.

29 29 29 D5

Digital I/O Bit 5 of 14-Bit Parallel Data Bus. High impedance when

RD = 1 or CS = 1.

30 30 30 D6

Digital I/O Bit 6 of 14-Bit Parallel Data Bus. High impedance when

RD = 1 or CS = 1.

31 31 31 D7

Digital I/O Bit 7 of 14-Bit Parallel Data Bus. High impedance when

RD = 1 or CS = 1.

32 32 32 D8

Digital Out Bit 8 of 14-Bit Parallel Data Bus. High impedance when

RD = 1 or CS = 1.

33 33 33 D9

Digital Out Bit 9 of 14-Bit Parallel Data Bus. High impedance when

RD = 1 or CS = 1.

34 34 34 D10

Digital Out Bit 10 of 14-Bit Parallel Data Bus. High impedance when

RD = 1 or CS = 1.

35 35 35 D11

Digital Out Bit 11 of 14-Bit Parallel Data Bus. High impedance when

RD = 1 or CS = 1.

36 36 36 D12

Digital Out Bit 12 of 14-Bit Parallel Data Bus. High impedance when

RD = 1 or CS = 1.

37 37 37 D13

Digital Out Bit 13 of 14-Bit Parallel Data Bus. High impedance when

RD = 1 or CS = 1.

38 38 38 DV

Digital-Supply Input. Apply +2.7V to +5.25V to DV

. Bypass DV

to DGND with a 0.1µF capacitor.

39 39 39 DGND

Digital-Supply GND. DGND is the power return for DV

. Connect

DGND to AGND at only one point (see the Layout, Grounding, and

Bypassing section).

40 40 40 EOC

End-of-Conversion Output. EOC goes low to indicate the end of a

conversion. EOC returns high after one clock period.
