General Description

logic diagram (positive logic) The SN65076B and SN75076B differential bus transceivers are monolithic integrated circuits designed for bidirectional data communication on multipoint bus transmission lines.

They are designed for noisy environments, where a low-impedance termination to ground is required.

D3 2 RE 1 R 7 A 6 B BUS The SN65076B and SN75076B combine a differential line driver and a differential input line receiver, both of which operate from a single 5-V power supply.

Key Features

  • positive- and negative-current limiting and thermal shutdown for protection from line fault conditions. Thermal shutdown is designed to occur at a junction temperature of approximately 150°C in the P package and 170°C in the D package. The receiver features a minimum input impedance of 12 kΩ, an input sensitivity of ± 200 mV, and a typical input hysteresis of 50 mV. The SN65076B is characterized for operation from.
  • 40°C to 105°C and the SN75076B is characterized for operation from 0°C t.
