8-BIT TO 9-BIT PARITY BUS TRANSCEIVERS

The ABT853 8-bit to 9-bit parity transceivers are designed for Communication between data buses. When data is transmitted from the A bus to the B bus, a parity bit is generated. When data is transmitted from the B bus to the A bus with its corresponding parity bit, the open-collector parity-error (ERR) output indicates whether or not an error in the B data has occurred. The output-enable (OEA and OEB) inputs CAN be used to disable the device so that the buses are effectively isolated. The ABT853 transceivers provide true data at their outputs. By Texas Instruments
