description
The ’ABT833 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 ’ABT833 provide true data at their outputs.
A 9-bit parity generator/checker generates a parity-odd (PARITY) output and monitors the parity of the I/O ports with the ERR flag. ERR is clocked into the register on the rising edge of the clock (CLK) input. The error flag register is cleared with a low pulse on the clear (CLR) input. When both OEA and OEB are low, data is transferred from...
