DS34C86TM Datasheet

Interface - Drivers, Receivers, Transceivers


The DS34C86TM is a quad differential line receiver designedto meet the RS-422, RS-423, and Federal Standards 1020and 1030 for balanced and unbalanced digital data transmission,while retaining the low power characteristics of CMOS.The DS34C86T has an input sensitivity of 200 mV over thecommon mode input voltage range of ±7V. Hysteresis is providedto improve noise margin and discourage output instabilityfor slowly changing input waveforms.The DS34C86T features internal pull-up and pull-down resistorswhich prevent output oscillation on unused channels.Separate enable pins allow independent control of receiverpairs. The TRI-STATE® outputs have 6 mA source and sinkcapability. The DS34C86T is pin compatible with theDS3486. DS34C86TM Features • CMOS design for low power• ±0.2V sensitivity over the input common mode voltagerange• Typical propagation delays: 19 ns• Typical input hysteresis: 60 mV• Inputs won’t load line when VCC = 0V• Meets the requirements of EIA standard RS-422• TRI-STATE outputs for system bus compatibility• Available in surface mount• Open input Failsafe feature, output high for open input
