Pin Descriptions
PIN
NAME
DESCRIPTION
1
GND
Ground return for comparators (0V).
2
V-
Negative supply voltage input (-5V).
3
V
REF
Reference voltage input (+2.5V).
4
AG
Analog ground reference (0V).
5
V
IN
Analog Input Voltage.
6
SET
Connect to V+ for proper operation.
7
BUSY
Output High-Conversion complete. Output Low - Conversion in progress. Output floats when chip is not selected (RD
and CS both high).
8
CLK
Clock input.
9
HOLD
Indicates start of conversion. Active low.
10
WR
Write input. With CS low, starts conversion when pulsed low; continuous conversions when kept low.
11
CS
Chip select input. Active low.
12
RD
Read input. With CS low, enables output buffers when pulsed low; outputs updated at end of conversion when kept low.
13
SMODE Slow memory mode input. Active high.
14
DG
Digital ground (0V).
15
BUS
Bus select input. High = all outputs enabled together D0 - D9, OVR. Low = outputs enabled by HBE.
16
HBE
Byte select (HBE/LBE) input for 8-bit bus. Input high-High byte select, D8-D9, OVR Input low-low byte select, D0-D7.
17
D0
Bit 0 (Least significant, LSB).
