PINOUT

Pin 12 — D

5 — Data Bit 5 if HBE is LOW; LOW if

HBE is HIGH.

Pin 13 — D

4 — Data Bit 4 if HBE is LOW; LOW if

HBE is HIGH.

Pin 14 —N.C.—This pin is not internally connected.

Pin 15 —N.C.—This pin is not internally connected.

Pin 16— DGND — Digital Ground. Connect

to pin 5, at the device.

Pin 17 — D

3 — Data Bit 3 if HBE is LOW; Data Bit

11 if HBE is HIGH.

Pin 18 — D

2 — Data Bit 2 if HBE is LOW; Data Bit

10 if HBE is HIGH.

Pin 19— D

1 — Data Bit 1 if HBE is LOW; Data Bit

9 if HBE is HIGH.

Pin 20 — D

0 — Data Bit 0 if HBE is LOW. Least

Significant Bit (LSB). Data Bit 8 if HBE is HIGH.

Pin 21 — HBE — High Byte Enable, When held

LOW, data output as 12-bits in parallel. When held

HIGH, four MSBs presented on pins 17–20, pins

10 – 13 output LOWs. Must be LOW to initiate

conversion.

Pin22—R/C—Read/Convert.Fallingedgeinitiates

conversion when CS is LOW, HBE is LOW, and

BUSY is HIGH.

Pin 23 — CS — Chip Select. Outputs in Hi-Z state

when HIGH. Must be LOW to initiate conversion or

read data.

Pin 24 — BUSY. Output LOW during conver-

sion. Data valid on rising edge in Convert

Mode.

Pin25 — N.C. —Thispinisnotinternallyconnected.

Pin26—V

SD — Positive Digital Power Supply, +5V.

Connect to pin 27, and bypass to DGND.

Pin 27 — V

— Positive Analog Power Supply.

+5V. Connect to pin 26, and bypass to AGND.

Pin28—N.C.—Thispinisnotinternallyconnected.
