DS34C87T  
CMOS Quad TRISTATE Differential Line Driver  
General Description  
Features  
n TTL input compatible  
n Typical propagation delays: 6 ns  
n Typical output skew: 0.5 ns  
The DS34C87T is a quad differential line driver designed for  
digital data transmission over balanced lines. The  
DS34C87T meets all the requirements of EIA standard  
RS-422 while retaining the low power characteristics of  
CMOS. This enables the construction of serial and terminal  
interfaces while maintaining minimal power consumption.  
=
n Outputs won’t load line when VCC 0V  
n Meets the requirements of EIA standard RS-422  
n Operation from single 5V supply  
The DS34C87T accepts TTL or CMOS input levels and  
translates these to RS-422 output levels. This part uses spe-  
cial output circuitry that enables the individual drivers to  
power down without loading down the bus. This device has  
separate enable circuitry for each pair of the four drivers.  
The DS34C87T is pin compatible to the DS3487T.  
n TRI-STATE outputs for connection to system buses  
n Low quiescent current  
n Available in surface mount  
All inputs are protected against damage due to electrostatic  
discharge by diodes to VCC and ground.
