Low Power CMOS Design
Three-State Outputs with Enable Pin
Meets the EIA RS-422 Requirements
Low Propagation Delays
High Speed
GENERAL DESCRIPTION
The ST34C87 is a CMOS quad differential line driver
designed to meet the standard RS-422 requirements and
digital data transmission over balanced lines. To improve
noise margin and output stability for slow changing input
signals, special hysteresis is built in the ST34C87 circuit.
The ST34C87 is a high speed CMOS line driver designed
to operate with MFM / RLL controllers and hard disk
drives as well as RS-422 digital data transmission
applications. ST34C87 is suitable for low power 5V
operation with high input voltage protection devices.
