QUAD RS-422 CMOS Differential Line Driver
June 1997-3
Features
D Pin-to-Pin patible with National DS34C87 D Low Power CMOS Design D Three-State Outputs with Enable Pin D Meets the EIA RS-422 Requirements D Low Propagation Delays D 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...
