The DS3862 is an octal high speed schottky bus transceiver intended for use with terminated 120? impedance lines. It is specifically designed
to reduce noise in unbalanced trans-mission systems. The open collector drivers generate pre-cise trapezoidal waveforms with rise and fall
times of 9 ns (typical), which are relatively independent of capacitive load-ing conditions on the outputs.This reduces noise coupling to the
adjacent lines without any appreciable impact on the maximum data rate obtainable with high speed bus trans-ceivers.Inaddition,the receivers
use a low pass filterincon-junction with a high speed comparator, to further enhance the noise immunity. Tightly controlled threshold levels on
the receiver provide equal rejection to both negative and positive going noise pulses on the bus.

The DS3862 external termination is intended to be a 180 resistor fromthebusto5Vlogicsupply,togetherwitha390resistor from the bus to ground.The
bus can be terminated at one or both ends.
