Quad Differential Line Receiver  
General Description  
Features  
Y
Military temperature range  
The DS26F32 is a quad differential line receiver designed to  
meet the requirements of EIA Standards RS-422 and RS-  
423, and Federal Standards 1020 and 1030 for balanced  
and unbalanced digital data transmission.

Input voltage range of  
7.0V (differential or common

mode) 0.2V sensitivity over the input voltage range  
Meets all the requirements of EIA standards RS-422  
and RS-423  
Y
The DS26F32 offers improved performance due to the use  
of state-of-the-art L-FAST bipolar technology. The L-FAST  
technology allows for higher speeds and lower currents by  
utilizing extremely short gate delay times. Thus, the  
DS26F32 features lower power, extended temperature  
range, and improved specifications.

The device features an input sensitivity of 200 mV over the  
g
input common mode range of 7.0V. The DS26F32 pro-  
vides an enable function common to all four receivers and

TRI-STATE outputs, with choice of complementary en-  
ables, for receiving directly onto a data bus  
Propagation delay 15 ns typical  
TRI-STATE outputs with 8.0 mA sink capability. Also, a  
É
fail-safe input/output relationship keeps the outputs high  
when the inputs are open.  
The DS26F32 offers optimum performance when used with  
the DS26F31 Quad Differential Line Driver.
