SN75C1168NSR Datasheet

RS-422 Interface IC


The SN75C1168NSR dual drivers and receivers are integrated circuits designed for balanced transmission lines. The devices meet TIA/EIA-422-B and ITU recommendation V.11.The SN75C1168NSR combine dual 3-state differential line drivers and 3-state differential line receivers, both of which operate from a single 5-V power supply. The driver and receiver have active-high and active-low enables,respectively, which can be connected together externally to function as direction control. The SN75C1168NSR drivers have individual active-high enables. SN75C1168NSR Features • Meet or Exceed Standards TIA/EIA-422-B and ITU Recommendation V.11• BiCMOS Process Technology• Low Supply-Current Requirements: 9 mA Max• Low Pulse Skew• Receiver Input Impedance ... 17 kit Typ• Receiver Input Sensitivity ... 1200 mV• Receiver Common-Mode Input Voltage Range of -7 V to 7 V• Operate From Single 5-V Power Supply• Glitch-Free Power-Up/Power-Down Protection• Receiver 3-State Outputs Active-Low Enable for SN65C1167 and SN75C1167 Only• Improved Replacements for the MC34050 and MC34051 CLC412AJE Applications• Power supply monitor for portable equipment such as notebook PCs, digital still cameras, PDAs and cellular phones • Constant voltage power monitor for cameras, video equipment and communication equipment • Power monitor and reset for CPUs and microcomputers
