NOTES: A. CL includes probe and jig capacitance.
B. All diodes are 1N3064 or equivalent.
C. For ’116 and SN75118, VH = 3 V, VL = – 3 V, the A input is at 0 V.
For SN75117 and SN75119, VH = 3 V, VL = 0, the A input is at 1.5 V.
D. When testing the ’116 and SN75118 receiver sections, the response-time control and the termination resistor pins are left open.
