DS3890 BTL Octal Trapezoidal Driver

DS3892 BTL Octal TRI-STATE Receiver

General Description

The DS3890 and DS3898 are designed specifically to over-

come problems associated with driving densely populated

backplanes. These products provide significant improve-

ment in both speed and data integrity in comparison to con-

ventional bus drivers and receivers. Their low output capaci-

tance, low voltage swing and noise immunity features make

them ideal for driving low impedance busses with minimum

power dissipation.

This is achieved by terminating the bus with a pull up resis-

tor. Both devices can drive an equivalent DC load of 18.5X

(or greater) in the defined configuration.

(General Description to be continued)

Features

Driver output capacitance less than 5 pF

1 volt bus signal reduces power consumption

The DS3890 features an open collector outputs that gener-

ate precise trapezoidal waveforms with typical rise and fall

times of 6 ns which are relatively independent of capacitive

loading conditions. These controlled output characteristics

significantly reduce noise coupling to adjacent lines.

Trapezoidal driver waveforms (t , t , typically 6 ns) re-

duces noise coupling to adjacent lines

Precise receiver threshold track the bus logic high level

to maximize noise immunity in both logic high ahd low

states

To minimize bus loading, the DS3890 also features

Open collector driver output allows wire-or connection

Advanced low power schottky technology

Glitch free power up/down protection

TTL compatible driver and control inputs and receiver

output

schottky diode in series with the open collector outputs that

isolates the driver output capacitance in the disabled state.

With this type of configuration the output low voltage is typi-

cally ‘‘1V’’. The output high level is intended to be 2 volts.

BTL compatible
