SN75LBC968 具有有源终端的 9 通道总线收发器

The SN75LBC968 is a nine-channel transceiver with active termination that drives and receives the signals from the single-ended, parallel data buses such as the Small Computer-Systems Interface (SCSI) bus. The features of the line drivers, receivers, and active-termination circuits provide the optimum signal-to-noise ratios for reliable data transmission. Integration of the termination and transceivers in the LinBiCMOS™ process provides the necessary analog-circuit performance, has low quiescent power, and reduces the capacitance presented to the bus over separate termination and I/O circuits.

The transceivers of the SN75LBC968 can be enabled to function as totem-pole or open-drain outputs. The open-drain mode drives the wired-OR lines of SCSI (BSY, SEL, and RST) by inputting the data to the direction control input DE/RE instead of the A input
