DS3896/DS3897  
BTL Trapezoidal Transceivers  
with a pull up resistor to 2V at both ends. The device can  
drive an equivalent DC load of 18.5(or greater) in the  
above configuration.  
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 thresh-  
olds are referred to as Bus Transceiver Logic (BTL).  
Features  
n 8 bit DS3896 transceiver provides high package density  
n 4 bit DS3897 transceiver provides separate driver input  
and receiver output pins  
n BTL compatible  
n Less than 5 pF output capacitance for minimal bus  
loading  
n 1 Volt bus signal swing reduces power consumption  
n Trapezoidal driver waveforms (tr, tf 6 ns typical)  
reduce noise coupling to adjacent lines  
n Temperature insensitive receiver thresholds track the  
bus logic high level to maximize noise immunity in both  
high and low states  
n Guaranteed A.C. specifications on noise immunity and  
propagation delay over the specified temperature and  
supply voltage range  
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 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.  
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 com-  
parator, to further enhance the noise immunity and provide  
equal rejection to both negative and positive going noise  
pulses on the bus.  
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 out-  
put low voltage is typically “1V” and the output high level is  
intended to be 2V. This is achieved by terminating the bus
