... 1. Output Swing: Unloaded, the 42µA pull-down will bring the output within 300 mV of V− over the military temperature range. If more than 42µA is required, a resistor from output to V− will help. Swing across any load may be improved slightly if the load can be tied to V+, at the cost of poorer sink ...

Current source
A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it.A current source is the dual of a voltage source. The term constant-current 'sink' is sometimes used for sources fed from a negative voltage supply. Figure 1 shows the schematic symbol for an ideal current source, driving a resistor load. There are two types - an independent current source (or sink) delivers a constant current. A dependent current source delivers a current which is proportional to some other voltage or current in the circuit.
