†
Full range (MIN or MAX) for LM293A is 25°C to 85°C, and for LM393A is 0°C to 70°C. All characteristics are measured with zero common-mode
input voltage, unless otherwise specified.
§
The voltage at either input or common-mode should not be allowed to go negative by more than 0.3 V. The upper end of the common-mode voltage
range is V
CC+
− 1.5 V, but either or both inputs can go to 30 V without damage.
