Complementary outputs are recommended for use with line driver Ø1.00 Ø1.00 type (source/sink) outputs. When used with differential receivers, this combination provides a high degree of noise immunity. 5. Output IC’s: Output IC’s are available as either Line Driver (LD) or .75 .75 NPN Open Collector (OC) types. Open Collectors require pull-up resis- TYP TYP tors, resulting in higher output source impedance (sink impedance BORE Ø BORE Ø is similar to that of line drivers). In general, use of a Line Driver style +0.003/-0.000 +0.003/-0.000 Ø2.22 Ø2.22 BLIND SHAFT output is recommended.
