DS3862

Octal High Speed Trapezoidal Bus Transceiver

General Description

Features

n Guaranteed A.C. specifications on noise immunity and

propagation delay over the specified temperature and

supply voltage range

The DS3862 is an octal high speed schottky bus transceiver

intended for use with terminated 120Ω 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. In addition, the receivers use a low pass filter in con-

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.

n Temperature insensitive receiver thresholds track bus

logic level and respond symmetrically to positive and

negative going pulses

n Trapezoidal bus waveforms reduce noise coupling to

adjacent lines

n Open collector driver output allows wire-or connection

n Advanced low power schottky technology

n Glitch free power up/down protection on driver and

receiver outputs

n TTL compatible driver and control inputs, and receiver

outputs

The external termination is intended to be a 180Ω resistor

from the bus to 5V logic supply, together with a 390Ω resistor

from the bus to ground. The bus can be terminated at one or

both ends.

n Control logic is the same as the DS3896
