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. When driving the data through the A input, the outputs become totem poles and provide active signal negation for a higher voltage level on low-to-high signal transitions on heavily loaded buses. In either mode, the turn-on and turn-off output transition times are limited to minimize crosstalk through capacitive coupling to adjacent lines and RF emissions from the cable. The receivers are also designed for optimum analog performance by precisely controlling the input-voltage thresholds, providing wide input-voltage hysteresis and including an input-noise filter. These features significantly increase the likelihood of detecting only the desired data signal and rejecting noise.
