Ground return for comparators (0V).
Negative supply voltage input (-5V).
Reference voltage input (+2.50V).
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 se-
lected (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.
Slow memory mode input. Active high.
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,
