Ground return for comparators (0V).
Negative supply voltage input (-5V).
Reference voltage input (+2.5V).
Analog ground reference (0V).
Analog Input Voltage.
Connect to V+ for proper operation.
Output High-Conversion complete. Output Low - Conversion in progress. Output floats when chip is not selected (RD
and CS both high).
Clock input.
Indicates start of conversion. Active low.
Write input. With CS low, starts conversion when pulsed low; continuous conversions when kept low.
Chip select input. Active low.
Read input. With CS low, enables output buffers when pulsed low; outputs updated at end of conversion when kept low.
Digital ground (0V).
Bus select input. High = all outputs enabled together D0 - D9, OVR. Low = outputs enabled by 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.
