DS3896/DS3897

BTL Trapezoidal™ Transceivers

equivalent DC load of 18.5Ω (or greater) in the above config-

uration.

General Description

These advanced transceivers are specifically designed to

overcome problems associated with driving a densely popu-

lated backplane, and thus provide significant improvement in

both speed and data integrity. Their low output capacitance,

low output signal swing and noise immunity features make

them ideal for driving low impedance buses with minimum

power consumption.

These signalling requirements, including a 1 volt signal swing,

low output capacitance and precise receiver thresholds are

referred to as Bus Transceiver Logic (BTL).

Features

8 bit DS3896 transceiver provides high package density

■

4 bit DS3897 transceiver provides separate driver input

and receiver output pins

The DS3896 is an octal high speed schottky bus transceiver

with common control signals, whereas the DS3897 is a quad

device with independent driver input and receiver output pins.

The DS3897 has a separate driver disable for each driver and

is, therefore, suitable for arbitration lines. The separate driver

disable pins (En) feature internal pull ups and may be left open

if not required. On the other hand, the DS3896 provides high

package density for data/address lines.

BTL compatible

■

Less than 5 pF output capacitance for minimal bus loading

■

1 Volt bus signal swing reduces power consumption

Trapezoidal driver waveforms (t_r, t_f≃ 6 ns typical) reduce

noise coupling to adjacent lines

Temperature insensitive receiver thresholds track the bus

logic high level to maximize noise immunity in both high

and low states

■

The open collector drivers generate precise trapezoidal

waveforms, which are relatively independent of capacitive

loading conditions on the outputs. This significantly reduces

noise coupling to adjacent lines. In addition, the receivers use

a low pass filter in conjunction with a high speed comparator,

to further enhance the noise immunity and provide equal re-

jection to both negative and positive going noise pulses on

the bus.

Guaranteed A.C. specifications on noise immunity and

propagation delay over the specified temperature and

supply voltage range

■

Open collector driver output allows wire-or connection

■

Advanced low power schottky technology

To minimize bus loading, these devices also feature a schot-

tky diode in series with the open collector output that isolates

the driver output capacitance in the disabled state. The output

low voltage is typically “1V” and the output high level is in-

tended to be 2V. This is achieved by terminating the bus with

a pull up resistor to 2V at both ends. The device can drive an

Glitch free power up/down protection on driver and

receiver outputs

TTL compatible driver and control inputs and receiver

outputs
