Texas Instruments SN75162B
the SN75162B allows the REN and IFC transceivers to be controlled independently. The driver outputs (GPIB I/O ports) feature active bus-terminating resistor circuits designed to provide a high impedance to the bus when supply voltage VCC is 0. The drivers are designed to handle loads up to 48 mA of sink current.SN75161B, SN75162B OCTAL GENERAL-PURPOSE INTERFACE BUS TRANSCEIVERS D Meets IEEE Standard 488-1978 (GPIB) D 8-Channel Bidirectional Transceivers D Power-Up/Power-Down Protection (Glitch Free) D Designed to Implement Control Bus Interface D SN75161B Designed for Single Controller D SN75162B Designed for Multiple Controllers D High-Speed, Low-Power Schottky Circuitry D Low Power Dissipation . . . 72 mW Max Per Channel D Fast Propagation Times . . . 22 ns Max D High-Impedance pnp Inputs D Receiver Hysteresis . . . 650 mV Typ D Bus-Terminating Resistors Provided on Driver Outputs D No Loading of Bus When Device Is Powered Down (VCC = 0) description The SN75161B and SN75162B eight-channel, general-purpose interface bus transceivers are monolithic, high-speed, low-power Schottky devices designed to meet the requirements of IEEE Standard 488-1978. Each transceiver is designed to provide the bus-management and data-transfer signals between operating units of a single- or multiple-controller instrumentation system.
