• Manufacturer Part Number: DS36F95M
• Description: EIA-485/EIA-422A Differential Bus Transceiver
• Manufacturer: National Semiconductor

Parameter Measurement Information
Note 12: The input pulse is supplied by a generator having the following characteristics: PRR = 1.0 MHz, 50% duty cycle, t
Note 13: C
Note 14: DS16F95/DS36F95 Driver enable is Active-High.
Note 15: All diodes are 1N916 or equivalent.
Note 16: Testing at 20 pF assures conformance to 5 pF specification.
Typical Application
The line should be terminated at both ends in its characteristic impedance, typically 120 .
Stub lengths off the main line should be kept as short as possible.
L
includes probe and stray capacitance.
