Texas Instruments SN75ALS161

the sn75als161 eight-channel general-purpose interface bus transceivers are high-speed advanced low-power schottky-process devices designed to provide the bus-management and data-transfer signals between operating units of a single-controller instrumentation system. when combined with the sn75als160 octal bus transceivers this device provides a complete 16-wire interface for the ieee 488 bus. the sn75als161 device features eight driver-receiver pairs connected in a front-to-back configuration to form input/output (i/o) ports at both the bus and terminal sides. the direction of data through these driver-receiver pairs is determined by the direction-control (dc) and talk-enable (te) signals. the driver outputs general-purpose interface bus (gpib i/o ports) feature active bus-terminating resistor circuits designed to provide a high impedance to the bus when vcc = 0. view all in datasheet
