description  
The SN75ALS056 is an eight-channel,  
monolithic, high-speed, advanced low-power  
Schottky (ALS) device designed for two-way data  
communication in  
a
densely populated  
backplane. The SN75ALS057 is a four-channel  
version with independent driver-input (Dn) and  
receiver-output (Rn) pins and a separate driver  
disable for each driver (En).  
These transceivers feature open-collector driver outputs with series Schottky diodes to reduce capacitive  
loading to the bus. By using a 2-V pullup termination on the bus, the output signal swing is approximately 1 V,  
which reduces the power necessary to drive the bus load capacitance. The driver outputs generate trapezoidal  
waveforms that reduce crosstalk between channels. The drivers are capable of driving an equivalent dc load  
as low as 18.5 Ω. The receivers have internal low-pass filters to further improve noise immunity.  
The SN75ALS056 and SN75ALS057 are characterized for operation from 0°C to 70°C.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.  
†
The transceivers are suitable for IEEE Standard 896 applications to the extent of the operating conditions and characteristics specified in this  
data sheet.

PRODUCTION DATA information is current as of publication date.  
Products conform to specifications per the terms of Texas Instruments
